Climate change adaptation requires changes in what we grow. Because of weather challenges, most exotic fruits and vegetables are grown outside the UK. Will the rise in temperatures in Britain provide an opportunity to grow such crops? How can black women get involved in this opportunity?
Relevant answer
Answer
Dear Salomey Mettle , I'm fascinated by your choice to ask about black women specifically. The only reason I can think may be data showing that black women may be less likely to be rich enough to buy the land or equipment they need, but otherwise can't think of obstacles to black women specifically rather than obstacles to anybody want to become a farmer, especially in the UK.

Entre los retos principales podemos encontrar las especificaciones técnicas para poder lograr un cultivo exitoso de estas especies, lo cual implica una elevada capacitación por parte de los resposables de estos cultivos. Otro reto es el desarrollo de dietas funcionales, que a diferencia de los animales terrestres, dulceacuicolas o estuarinos, en el caso de las especies marinas, primero, poco se conoce de sus requerimientos nutricionales , segundo, de las que actualmente se conoce algo, se observa una exigencia de mayor calidad nutricional en los insumos usados para las dietas. Todo lo anterior sugiere que la investigación debería enfocarse en especies clave para la comercialización, de manera que se logre el dominio de la técnica de cultivo y desarrollo de dietas prácticas en menor tiempo y a menor costo, lo que ayudaría a hacerlas más atractivas para la inversión, en lugar de dispersar la poca fuerza de investigación actual en muchas especies y con pocos avances en cada una de ellas.

For my own research, I use LSTM and MLP algorithms, where weather data is part of the input data. Unfortunately, data related to temperature and precipitation have not been recorded in many time periods, and the number of empty data is high. What is the solution to manage this missing data?
Relevant answer
Answer
There are several ways to handle missing data; the best approach depends on what is most beneficial for your research. First, if removing the missing intervals doesn’t add value, you could try resampling the data, ignoring the NaN values. This can help reduce the impact of missing data by aggregating the dataset, for example, resampling from minutes to hours. However, this approach may not work well if you're interested in capturing fine-grained dynamics in the smaller intervals. Another option is to use data from a nearby weather station to estimate or predict the missing values for your site, which can be useful for filling gaps. Finally, you can also leverage global models or satellite data over your area of interest to predict and fill in the missing intervals.

I need to compute vapour pressure deficit (VPD) from ECMWF ERA-5 data set.
Can anyone help me to select appropriate ERA-5 parameters and corresponding equations ?
My first guess would be:
VPD = SVP – AVP
with AVP = actual vapor pressure
SVP = saturation vapor pressure
using formulation of Bougeault (1982):
SVP = 610.78 x e^(17.2694 x (Td-273.16) / (Td-35.86))
AVP = 610.78 x e^(17.2694 x (T -273.16) / (T -35.86))
With T = air temperature ("2m temperature" ERA5 parameter)
Td = dewpoint temperature ("2m dewpoint temperature " ERA5 parameter)
if correct, VPD is thus derived from T and Td
Thanks for helping

Dear Colleagues,
We invite you to submit your valuable articles to the Special Issue "Recent and Future Cyclonic Activity and Associated Weather Extremes"
The aim of this Special Issue is to provide recent advances in the field of study on cyclonic activity change encompassing issues of changes in the past, revealing current tendencies and scenarios of changes in the near future. A key task for SI is gathering high-quality papers concerning seasonal- interannual-to-decadal variability of synoptic patterns that drive cyclones evolution; studies on extraction and interpretation of multidecadal trends are also welcomed. Expected future trends of cyclones frequency and intensity associated with the anthropogenic factors is the second task of SI. Besides, it is well-known that cyclones can cause extreme weather conditions and may trigger natural disasters. Therefore, special attention should be paid to study of extremes associated with cyclones, and this is the third task of SI. Actually, these problems should be solved using both various probabilistic and interdisciplinary methods of experimental data analysis, as well as numerical, stochastic and statistical modeling including outputs of CORDEX, CMIP6 etc.
Above tasks are very important not only from academic point of view, but also for a high number of applications which are also in the focus of the SI. Among them are sustainable agriculture, social infrastructure and recreational potential, optimal design and use of wind power plants, transport and maritime safety etc. The scope of these problems covers an essential part of issues to be resolved to attain optimal regional strategies for adaptation and sustainable planning all over the World.
Topics of interest for the Special Issue include but are not limited to:
  • Climatology of cyclones in the regions.
  • Climatology of extreme events associated to the cyclones/anticyclones
  • Low-frequency variability of cyclone/anticyclone activity associated with the global climate modes
  • Cyclone/anticyclone activity under the climate change
  • Methods and models for cyclonic climate analysis
  • Predictability of cyclonic activity change in the different regions
  • Practical applications
  • Scenarios of cyclonic activity change in the future.
  • Future extreme events associated with cyclonic activity
  • Low-frequency variability of future cyclonic activity associated with the global climate modes

The question of whether deep learning models can outperform traditional numerical weather prediction (NWP) systems is increasingly relevant in meteorology. NWP relies on complex physical models and equations to simulate atmospheric processes, but it can be computationally expensive and slow. In contrast, deep learning models, those utilizing neural networks like LSTM, CNN, and Transformer architectures, offer the potential for faster and more data-driven predictions by learning complex patterns directly from historical weather data. While deep learning shows promise in specific applications such as short-term forecasting, its ability to consistently surpass NWP remains an active area of research requiring further validation.

Of course, Deep Learning can outperform traditional methods in forecasting weather. Recently, Google DeepMind released a state-of-the-art deep learning-based model for weather forecasting that is both more accurate and requires fewer computational resources.

Yes, You raise a valid point! Yes, the hydrosphere is approximately mass-conserved, meaning the total amount of water on Earth remains relatively constant. However, water resource distribution and allocation are changing due to various factors, including global warming.
Global warming affects the water cycle, leading to changes in:

The British Premier league has 20 teams, they play 380 games in a season, each team plays with each one game at home and one game away. 17 out of these 20 teams were playing in the previous season and all results are available. 3 teams are new, we ignore them and only predict for those that played previous season.
How to predict outcomes in a new season for these 17 teams using historic records and newly obtained results. For example, when several games already played in a new seasons, they can be taken on account. We need to predict the exact score, not only a winner. Winners are obvious in most games. When predicting scores we need predict them as vectors, so if it is 3:2 that does not mean we can predict 3 by one model and 2 by another, it is clear that both numbers are related. Also the model must be probabilistic. So we have to predict probabilities of multiple possible outcomes.
I'm not trying to get quick rich. Bookmakers disallow to use AI and disqualify those who, may use them. Also, it is already known that AI predicts better than humans. Also, bookmakers are simply exclude those who win too much without any explanation, so it is not a money making method, but a research.
The prediction must use only the scores from the previous seasons and not any other insider information, such as traumas, new players, new trainers, weather, rain, wind and so on. These factors are considered as random noise and expressed indirectly in probabilities.

Answer
I saw this concept, but each time I try it, I face problem. I don't have critical parameters to build the model. Each valid example does have it, but I don't have. So it looks like it is fake or detached from reality and people who promote it, found some non-common examples.
The data you have looks like follows:
Team A at home, team B away 3:2
Team A at home, team C away 1:2
---- and so on
Team K at home, team B away 2:2
Team K at home, team C away 3:1
---- and so on
The answer we want:
Team A at home, team K away
2:2 with probability 0.3
1:2 with probability 0.2
2:1 with probability 0.2

i am writing an assigment about endurance, where i am cycling for 1 month (cca. 16 tranings 2 day training successively; 1 day rest) and as a bonus i am trying to find colleration with weather and my cylcling time, avg., max. heart rate... (For example when the temperature was above 25 degrees my avg. HR was incereased...) Sadly weather isnt as simple as saying 20 degrees celcius is hot and 10 is cold and it becomes complicated with humiditity, wind, sun... The lap i am cyciling basically negates the effect of wind (for example if wind is blowing one way it helps me in the first half and its harder the second half) and geting accurate wind measurments is basically impossible. Still i want to know if there is an index, a formula that would accurately portray the effect of temperature and humidity? 30 degrees in 90% humidity with the sun out is not the same as 30 degrees with 30% humidity, so i was personally thinking of just putting this into "weather" units meaning 30 degrees and 90% would be 120 weather units, while the latter would be 60 weather units, in this case i would atleast have a more accurate scale. Maybe something like sun being out and shining on me for the whole ride would be a (multiplier)*2.

Dear colleagues, I am dealing with a change in the weather. I have monthly precipitation data dating back to around 1950. Can you please advise me on the statistical methods that experts use to evaluate the distribution of rainfall? I have determined from the analysis that the precipitation trends in the areas I am studying are not statistically significant (Mann-Kendall trend test). In some places, the long-term rainfall is slightly decreasing, while in others, it is slightly increasing. However, I know from other articles that their distribution is changing. Periods without rain are becoming longer, and this dry spell is being replaced by heavy rainfall. The rainfall is not uniform; its distribution is different from that in the past.
What method is appropriate for such an analysis?

Lukas Hlisnikovsky I believe that the temporal variations in the precipitation patterns in neighboring areas will have an impact. In my experience, based on observations in the Eastern European region, between the borders of Poland and the Urals (I am sorry, but I do not have access to published data for this specific area), in recent years, the predominant summer movement of humid air has shifted from a west-to-east direction to a south-to-north direction. This has led to precipitation often falling along a narrow corridor stretching from the Black Sea coast to the White Sea, with neighboring areas not being significantly affected.

Does the concentration of CO2 gas in the atmosphere cause warming of the earth's atmosphere? Or does it lead to less rainfall when it warms up? Or does the warming of the earth's atmosphere lead to an increase in rainfall on the earth's surface?
Equilibrium Climate Sensitivity (ECS) is the global mean change in surface temperature for a doubling of CO2 from the pre-industrial (PI) value. ECS is one of the key metrics used in assessing future global warming, and therefore plays a very important role in climate change related policy-making. One important question in this regard is how ECS changes in a warmer world. Several studies found that ECS increases at higher CO2 concentrations (e.g., Bloch-Johnson et al., 2021; Colman & McAvaney, 2009; Gregory et al., 2015; Meraner et al., 2013). And, more recently, Mitevski et al. (2021) found a non-linear and non-monotonic dependence of ECS on CO2 concentrations. In addition to the surface temperature response, the precipitation response is another critical aspect of climate change. To evaluate precipitation changes, the key metric used is Hydrological Sensitivity (HS). HS is defined as the difference in global mean precipitation per one degree of global mean temperature change from the PI control state. Previous studies have explored the response of the hydrological cycle to global warming by examining HS in terms of the global energy budget, and have described the mechanisms affecting it (e.g., Allen & Ingram, 2002; Held & Soden, 2006; Jeevanjee & Romps, 2018; O'Gorman et al., 2011). The fact that HS is energetically constrained means that the precipitation response can be separated into fast and slow components. The fast response depends only on the CO2 concentrations in the atmosphere, before the surface temperature has time to warm, and results in a decrease in precipitation. The slow response, in contrast, is associated with surface warming, and results in an increase in precipitation (Andrews et al., 2010).

Abbas,
1) Yes, the rising carbon dioxide content of the atmosphere does lead to an increase in the surface and globally-averaged air temperature.
2) As the partial pressure of water vapour is a strong function of temperature (and that vapour is also a 'greenhouse gas') we expect to see a rise in the global humidity - that in various locales should result in more rainfall.
Neither of these are contentious matters and are well-addressed in the literature.

I recommend Google Scholar.
Very useful.
Mrutyunjay Padhiary added a reply:
Through the greenhouse effect, the amount of carbon dioxide (CO2) gas in the atmosphere is a significant contributor to global warming with many other greenhouse gases. Heat from the sun is trapped in the atmosphere when CO2 and other greenhouse gases build up, preventing it from escaping back into space. Global warming is the term for the total rise in temperature that results from this. Rainfall patterns can be impacted by Earth's atmosphere warming, while there is a complex relationship between CO2 concentrations and rainfall that varies based on local climate dynamics. Higher temperatures generally have the potential to alter the rates of evaporation and atmospheric circulation, which in turn can affect the patterns of precipitation. higher moisture can be held by warmer air, which could result in higher evaporation from lakes, oceans, and land surfaces. In certain areas, the increased moisture in the atmosphere may be a factor in the intensity of rainfall events. Higher temperatures, however, can also bring about modifications to weather patterns, including adjustments to air circulation and modifications to precipitation distribution. Also, variables including local geography, atmospheric stability, and variations in cloud cover can all have an impact on changes in rainfall patterns. While some places might have more rainfall than others, other regions might see less rainfall or changes in the frequency and severity of precipitation events. The ecosystems, agricultural practices, water supplies, and human societies may all be significantly impacted by these modifications in rainfall patterns. All things considered, even while the rise in CO2 concentrations in the atmosphere is the main cause of global warming, temperature variations that follow can have an impact on precipitation patterns, which can have complicated and varied impacts on the distribution and intensity of rainfall.

While that number is well below the scientific boiling point of 100ºC that turns water from liquid into gas, "global boiling" is a term recently used to underline the severity of climate change."

Dear Doctor
"Both weather broadcasters and viewers have greatly benefited from the integration of AI technologies, revolutionizing how predictions are made and communicated. Here are some of the most common applications of AI within the field:
Weather Prediction
Using AI for weather prediction is not a new innovation and has been in use since the 1970s. The weather models that broadcasters rely on to make accurate forecasts consist of complex algorithms run on supercomputers. Machine-learning techniques enhance these models by making them more applicable and precise.
Content Triggers
Besides traditional TV and radio broadcasts, many broadcasters today offer dedicated smartphone apps that provide up-to-the-minute weather information to viewers. One way AI helps broadcasters personalize the app experience is by enabling content triggers. A content trigger is a set of weather factors that automatically trigger an action in the app, such as sending the user a notification. For example, a broadcaster could set a trigger to send viewers safety graphics when temperatures in their area exceed a certain threshold for a certain amount of time in a day. These content triggers ensure that individuals receive timely and relevant information, enhancing their awareness and preparedness in weather-related situations.
Severe weather & weather alerts
On the forecasting side, by analyzing real-time data, AI can rapidly identify potential hazards such as lightning strikes, high winds or flash flooding. Then, in-app AI plays a crucial role in sending viewers automated severe weather alerts to keep them safe.

Question
1 answer
  • Describe methods for determining vapor pressure and relative humidity.
  • Analyze the relationship between vapor pressure and relative humidity.
  • Summarize how these measurements contribute to weather predictions.
Relevant answer
Answer
Vapor Pressure:
  1. Dew Point Method:This method involves cooling a surface until dew or frost forms. The temperature at which this occurs is the dew point, which is directly related to vapor pressure. Instruments like dew point hygrometers can measure the temperature at which condensation begins.
  2. Psychrometry:Psychrometers consist of two thermometers, one with a wet bulb and the other with a dry bulb. By comparing the temperatures, you can determine the vapor pressure and, subsequently, relative humidity. Charts or equations are then used to convert the temperature readings into vapor pressure.
  3. Hygrometers:Various types of hygrometers, such as hair tension, capacitive, and resistive hygrometers, can be used to measure the humidity in the air. These devices typically rely on the change in properties of a material with humidity.
Relative Humidity:
  1. Psychrometry:As mentioned earlier, a psychrometer can be used to measure both dry and wet bulb temperatures. Relative humidity is then determined by comparing these temperatures and using psychrometric charts or equations.
  2. Gravimetric Method:In this method, a sample of air is passed over a substance that absorbs moisture. The change in weight of the absorbing material before and after exposure is used to calculate the absolute humidity, from which relative humidity can be determined.
  3. Electronic Hygrometers:Electronic hygrometers often use sensors such as capacitive, resistive, or thermal sensors to measure humidity. The sensors produce an electrical signal proportional to the moisture content, and this signal is then converted into a percentage of relative humidity.
  4. Chilled Mirror Hygrometers:These hygrometers measure the dew point temperature by cooling a surface until dew forms. The temperature at which dew forms is directly related to the relative humidity of the air.
  5. Infrared Hygrometers:Infrared hygrometers measure the absorption of infrared radiation by water vapor in the air. The amount of absorption is used to calculate the relative humidity.
It's important to note that calibration and proper maintenance are crucial for the accuracy of these instruments. Additionally, environmental factors such as temperature and pressure can influence the measurements, so corrections may be necessary for accurate results.
Analyze the relationship between vapor pressure and relative humidity.
Vapor pressure and relative humidity are closely related atmospheric properties that describe the moisture content of the air. Understanding the relationship between these two concepts is crucial in meteorology, agriculture, and various industrial processes. Let's delve into the connection between vapor pressure and relative humidity:
  1. Definition:Vapor Pressure: It is the pressure exerted by the water vapor molecules in the air. It represents the tendency of water molecules to evaporate into the air. Relative Humidity: It is the ratio of the current vapor pressure to the saturation vapor pressure at the same temperature, expressed as a percentage. It indicates how close the air is to being saturated with moisture.
  2. Direct Relationship:As the vapor pressure increases, the relative humidity also increases, assuming constant temperature. When the air holds more water vapor (higher vapor pressure), the relative humidity increases because the air is closer to being saturated.
  3. Saturation:When the air is saturated (100% relative humidity), the vapor pressure is equal to the saturation vapor pressure at that temperature. Any further increase in vapor pressure beyond this point leads to the formation of visible moisture, such as dew, fog, or clouds.
  4. Temperature Influence:Warmer air can hold more water vapor before reaching saturation. Therefore, at higher temperatures, the vapor pressure can be higher without reaching 100% relative humidity. Conversely, cooler air reaches saturation with lower vapor pressure, and a small increase can lead to higher relative humidity.
  5. Dynamic System:The relationship between vapor pressure and relative humidity is dynamic and is influenced by changes in temperature, pressure, and the addition or removal of moisture. Cooling the air at constant moisture content increases relative humidity, potentially leading to condensation.
  6. Meteorological Implications:Meteorologists use the concept of relative humidity to assess the likelihood of precipitation. If the air is nearly saturated (high relative humidity), there is a greater potential for clouds and precipitation.
  7. Comfort and Perception:High relative humidity can make the air feel warmer due to reduced evaporative cooling, while low relative humidity can lead to a perception of dryness.
Understanding the relationship between vapor pressure and relative humidity is essential for predicting weather patterns, managing indoor environments, and optimizing industrial processes where moisture control is critical. It provides insights into the moisture-holding capacity of the air and helps in making informed decisions related to various applications.
Summarize how these measurements contribute to weather predictions
Measurements of vapor pressure and relative humidity play a crucial role in weather predictions by providing insights into the moisture content of the atmosphere. Here's a summary of their contributions to weather forecasting:
  1. Precipitation Forecasting:High relative humidity indicates that the air is near saturation, suggesting favorable conditions for cloud formation and precipitation. Meteorologists use these measurements to assess the likelihood and intensity of rainfall, snow, or other forms of precipitation.
  2. Cloud Formation and Fog Prediction:High relative humidity often leads to the formation of clouds or fog as the air becomes saturated with moisture. Monitoring vapor pressure and relative humidity helps predict the occurrence and persistence of clouds and fog in different atmospheric conditions.
  3. Temperature Regulation and Heat Index:Relative humidity affects the perception of temperature. Meteorologists consider both air temperature and humidity to calculate the heat index, which reflects how the combination of these factors feels to humans. Understanding the moisture content helps in assessing the potential impact of weather conditions on human comfort and health.
  4. Storm Development:Rapid changes in vapor pressure and relative humidity can be indicative of atmospheric instability, which is a key factor in the development of severe weather conditions such as thunderstorms. Monitoring these parameters aids in identifying regions with high convective potential and the likelihood of thunderstorm formation.
  5. Dew Point and Comfort Predictions:Dew point, related to vapor pressure, is used to gauge the temperature at which air becomes saturated, leading to dew formation. Knowledge of dew point and relative humidity helps in predicting comfort levels and assessing the potential for condensation on surfaces.
  6. Hydrological Cycle Assessment:Vapor pressure and relative humidity measurements contribute to understanding the different phases of the hydrological cycle, including evaporation, condensation, and precipitation. This information is crucial for assessing water availability, drought conditions, and flood risks.
  7. Climate Modeling and Research:Long-term measurements of vapor pressure and relative humidity contribute to climate modeling and research by providing data on trends and patterns in atmospheric moisture content. These measurements aid in understanding climate variability and changes over extended periods.
In summary, vapor pressure and relative humidity measurements are fundamental for weather predictions, helping meteorologists anticipate precipitation, assess cloud and fog formation, understand temperature perception, predict storm development, and contribute to broader studies of climate and the hydrological cycle. These measurements provide valuable information for improving the accuracy and reliability of weather forecasts, benefiting various sectors such as agriculture, transportation, and disaster preparedness.

Dear WRF-Chem users,
I am interested in acquiring knowledge regarding the use of the restart functionality inside the Weather Research and Forecasting (WRF) model. There are three domains in a nested structure, with sizes of 9, 3, and 1 km.
The whole duration of the run was allocated to a period of 19 days, with the initial 14 days designated for spin-up.
Could you please provide instructions on how to utilize the restart option? Furthermore, while checking the user guide, I discovered that it was inadequate in providing clear instructions to follow.
Could you kindly provide me with guidance in this matter?
Sincere regards,
Relevant answer
Answer
Setareh Rahimi, the restart option is a very practical option in namelist. If the model blows up mid-way, it is the way to restart the run from termination time only, not to renew the run from the beginning. Here are some important tips:
1. You have to choose the restart interval in such a way that one overlap time exists for your three domains. Let's assume, you are dumping data 6 hourly, 3 hourly, and 1 hourly for domain 1, domain 2, and domain 3, respectively. The best way is to keep your restart interval 6 hourly. One important thing is that you have to keep "restart = .false.," in namelist.input until your model blows up.
2. After keeping restart 6 hourly, WRF would start creating restart files in multiple of 6 hours along with output file.
3. If the model blows up, then you need to change false to true in "restart = .true. in namelist.input. You need to find the common overlap time in restart files for 3 domains. That particular time is the time you have to insert in start_year, start_month, start_day, start_hour, start_minute in namelist.input.
4. Then go for the WRF run again. It will take the ICs/BCs from restart files and resume the run.
5. Later you will find, that it creates different WRF output files. Finally, you have to merge these outputs if you want all time steps to be kept in a single NetCDF file.
Hope this helps.

"Abstract
Many reports state how serious the problems associated with cracking in reinforced concrete (RC) structures worldwide. The cracking can cause damage and destruction to RC structures. The cracks are the damage to RC structures that require repair or replacement. Analysis of the damage level as early as possible on the RC structure cracks can reduce the greater impact and streamline the cost of repairing the concrete structure. Therefore, non-destructive testing (NDT) method is needed on the RC structure, namely: visual inspection technique. The image obtained from the visual inspection is then analyzed using image processing. After that, the concrete structure with cracks is tested for quality (compressive strength) using the rebound hammer technique with a rebound index. From the image processing and rebound index results, the damage from the cracks that occurred can be concluded so that the repairs become more effective and efficient."

In light of the urban heat island (UHI) effect and variations in urban microclimates, how do researchers account for these localized impacts when analyzing temperature data, especially after weather station relocations? Are there any specific methodologies or correction factors used to ensure that the data truly represents the ambient conditions and isn't skewed by urban developments?
Relevant answer
Answer
Adjusting temperature data after weather station relocations due to urban heat island effects and microclimate variations is a crucial step in maintaining the accuracy and consistency of climate records.
Here's how such adjustments are typically approached:
  1. Comparison and Analysis: Before and after relocating a weather station, it's important to compare the temperature data from the old and new locations. This allows for the identification of any discrepancies and trends that might have arisen due to the changes in the station's surroundings.
  2. Local Conditions Assessment: Understand the local conditions of the new station's surroundings, particularly with regard to urban development, changes in land use, and potential heat sources. Urban areas tend to have higher temperatures due to the urban heat island effect caused by human activities, buildings, and asphalt that absorb and emit heat.
  3. Site Characteristics Consideration: Analyze the characteristics of the new station's site, including its elevation, proximity to heat sources (like buildings or industrial facilities), and presence of green spaces. These factors can significantly influence local microclimates.
  4. Homogenization: Homogenization is a process used to correct temperature records for non-climatic factors that might affect data consistency. It involves identifying and adjusting any artificial changes in temperature records caused by station relocations, changes in instrumentation, or shifts in observation times.
  5. Temperature Gradient Analysis: Analyze temperature gradients between the old and new station locations and surrounding areas. If there are significant differences, adjustments may be needed to account for these variations.
  6. Statistical Methods: Statistical methods, such as regression analysis, can be employed to develop correction factors based on the observed differences between the old and new station data. These correction factors can then be applied to the data collected at the new location.
  7. Reference Stations: Sometimes, reference stations located in relatively undisturbed areas are used to calibrate and validate the data collected from relocated weather stations. This can help in identifying and quantifying the effects of urban heat islands.
  8. Long-term Data Patterns: Consider long-term data patterns, including seasonal and diurnal variations. Adjustments should take into account how temperature trends might change due to urbanization and microclimate alterations.
  9. Expert Judgment: Meteorologists and climatologists often play a role in making adjustments based on their expertise and understanding of local climate conditions. Their judgment can be crucial in interpreting data anomalies and making appropriate corrections.
  10. Documentation and Reporting: It's important to thoroughly document all adjustments made to the temperature data, including the reasons for adjustments, methodologies used, and any assumptions made. Transparent reporting ensures the credibility and reproducibility of the adjustments.
Adjusting temperature data post weather station relocations is a complex process that requires a combination of scientific methods, domain expertise, and careful consideration of local conditions. It's important to ensure that adjustments are made responsibly to maintain the integrity of climate records and provide accurate information for climate research and decision-making.

Answer
Extensive work on this topic https://www.disasterdiplomacy.org/cep.html finds mixed results, suggesting that much more than weather, climate, and climate change are the real causal factors for resource-related conflict and resource-related peace.

I want to build a complete weather statistical model to predict the weather.
Where the model is able to predict all atmospheric layers.
And to be able to display the predicted results in the form of interactive weather maps.
Relevant answer
Answer
A short answer: it is not possible build a long term (longer than ~ 1 week or so) complete statistical model for all classes to predict the weather.
Indeed, pressure, temperature, wind, and precipitation levels topographical features should be included in the numerical weather models (NWM). Also, a nonlinear coupling of the ocean to the atmosphere must be included in the model. This coupling is used in global forecast models such as ocean events El Nino and La Nina. These events correspond to an oscillation of the ocean-atmosphere system. The NWM is not an exact description of the atmosphere. Many physical processes and small-scale weather elements such as boundary layers, heat and mass exchange, cloud cover, etc. are parametrized, e.g., instead of each individual cloud some parameters are being used such as average cloudiness to represent the cloud cover in a computational cell. Without such simplification, even a supercomputer cannot complete the weather calculation in a reasonable amount of time. NWM is usually run on an evenly spaced 3-dimensional grid, so initial data are needed for all grid points. However observational data are not available for great portions of the ocean and some land areas, therefore some interpolation is needed for such missing initial data points. Because of all these issues, such as nonlinear nature of the models and the initial data that cannot be precisely measured, a single weather forecast becomes increasingly inaccurate for 3 or 4 days ahead. In an attempt to push this limit, ensemble forecasts are generated, i.e. NWM are run a number of times with slightly different initial conditions to represent the uncertainties in the observation data and parametrizations. A measure of forecast uncertainty is the standard deviation of the ensemble member NWMs.
The bottom line: no reliable weather forecast is possible beyond a limit of about 1 week or so, and even this limit is often not achieved. See, for example, the NOAA site:
for animated plots for North America that contain 40 ensemble members and two control splits with the Global Ensemble Forecast System.

What are the most serious problems of civilization development that should be solved as soon as possible? What are the global problems for which research should be developed and solutions to these problems resolved in 2019 and in subsequent years?
One of such research problems, which should not be postponed for an indefinite future, is the need to develop environment-friendly sustainable economic development in order to slow down the adverse process of global warming.
With the warming of the Earth's climate, the risk of more dramatic climate cataclysms, including tsunamis, increases.
Tsunami may be a derivative of the global warming problem. Global warming generates an increase in climate disasters, including more cases of tsunamis.
But not only is the risk of more violent and more dramatic tsunamis rising. Also in recent years, there has been more other types of climate and natural climate catatics, such as droughts, rainstorms, tornadoes and weather anomalies.
At present, it should no longer be asked whether global warming generates an increase in natural disasters only what rate of growth will be recorded in the future? So many data, research centers confirms the progressing process of global warming, that the problem is unquestionable.
More and more data points to the growing risk of climate change, unfavorable for human and life on the Earth, increase of climate disasters, climatic and weather anomalies, which are the result of global warming, rising average annual temperature near the Earth's surface.
Now we should just ask: How can these adverse processes be counteracted? What ecological technologies, renewable energy sources, how to help natural environments, how to rebuild them, such as afforestation, to build natural ecosystems absorbing greenhouse gases?
How to develop ecological business ventures? How to create financing systems for this type of pro-ecological projects? How to dispel international cooperation in this matter? What actions should be taken to move towards the development of a new ecological green economy?
How to develop environmentally sustainable economic development to slow down the unfavorable warming of the Earth's climate?
