The main objective of this study was to investigate the variability in annual counts and the northern extent of cyclones in the North Atlantic in the years 1970–2019. Cyclones were divided into tropical cyclones (TCs), called hurricanes in the Atlantic, and extratropical cyclones (ETCs), transformed from TCs. Linear regression methods and Pearson’s...
The productivity response of a peatland ecosystem in Rzecin, Poland, was determined based on varying aerosols abundant in the atmosphere. The study was done with the use of a multifactorial model that combined atmospheric and ecosystem modules to describe plant photosynthetic ability from different perspectives. The Gross Ecosystem Production (GEP)...
Heavy snowfall events of possible sea‐effect origin, occurring on the southern Baltic Sea coast, are described in this study. The analysed region is not very snowy, with an average of 40 days with snow cover in the winter season and a mean maximum snow depth of 8‐12 cm. Twenty‐five snowfall events were selected using the threshold of 20 cm/2 days (...
The pure spectra acquisition of plant disease symptoms is essential to improving the reliability of remote sensing methods in crop protection. The reflectance values read from the pure spectra can be used as valuable training data for development of algorithms designed for plant disease detection at leaf and canopy scale. The aim of this paper is t...
Long-term trends in the historical frequency of environments supportive of atmospheric
convection are unclear, and only partially follow the expectations of a warming climate. This uncertainty is driven by the lack of unequivocal changes in the ingredients for severe
thunderstorms (i.e. conditional instability, sufficient low-level moisture, initia...
Hazardous events related to atmospheric precipitation depend not only on the intensity of surface precipitation, but also on its type. Uncertainty related to determination of the precipitation type (PT) leads to financial losses in many areas of human activity such as power industry, agriculture, transportation, and many more. In this study, we use...
Air pollution continues to have a significant impact on Europeans living in urban areas. Each year, elevated concentration episodes of PMx are responsible for a large number of premature deaths (mostly due to heart diseases and strokes). Poland is one of the most polluted countries in Europe according to annual EEA reports. A high winter PMx concen...
Freely available and reliable meteorological datasets are highly demanded in many scientific and business applications. However, the structure of publicly available databases is often difficult to follow, especially for users who only deal with this kind of dataset on occasion. The "climate" R package aims to fill this gap with an easy-to-use inter...
The aim of the study was to analyze the atmospheric forcing of upwelling occurrence along the Polish and Lithuanian-Latvian coast. Upwelling cases were recognized based on the sea surface temperature in summer months (June–August). Atmospheric circulation was defined by indices of macroscale circulation patterns (North Atlantic Oscillation – NAO an...
Disease development in plants is strongly dependent on weather conditions, with temperature playing a particularly significant role by influencing latency period duration. Using two models describing the relationship between latency period and temperature, we performed simulations aimed at predicting changes in the latency period of leaf rust (Pucc...
This study analyzes the atmospheric forcing of upwelling occurrence along differently oriented coastlines of the southern Baltic Sea basin. The mean daily sea surface temperature (SST) data from the summer seasons (June-August) of the years 1982-2017 made the basis for the detection of upwelling cases. For the atmospheric part of the analysis, mont...
The correlation between the daily/monthly North Atlantic Oscillation (NAO) index and the daily/monthly anomalies of the summer (JJA) surface air temperatures in Poland is close to 0.00, being positive in most of the country (but hardly exceeding 0.15) and negative in the southeast. Therefore, the regional scale circulation patterns other than NAO w...
A long-term series of meteorological measurements will allow for a better understanding of the rate and nature of climate change. Such analysis presumes a historical knowledge of the particular place of measurements and changing measurement techniques, as well as a further evaluation of the quality of the available data. This research focuses on th...

The paper presents historical (1971-2015) and scenario-based (2006-2100) changes in surface water temperatures in 10 lakes of Poland. The analysis of historical measurement (1971-2015) showed that mean annual lake surface water temperature (LSWT) was characterised by an increasing tendency by 0.37°C∙dec-1 on average, and was higher by 0.01°C∙dec-1...
Changes in the timing of plant phenological phases are important proxies in contemporary climate research. However, most of the commonly used traditional phenological observations do not give any coherent spatial information. While consistent spatial data can be obtained from airborne sensors and preprocessed gridded meteorological data, not many s...
VALUE is an open European collaboration to intercompare downscaling approaches for climate change research, focusing on different validation aspects (marginal, temporal, extremes, spatial, process‐based, etc.). Here we describe the participating methods and first results from the first experiment, using “perfect” reanalysis (and reanalysis‐driven r...
We compare over 1 million sounding measurements with ERA-Interim reanalysis for the 38-yr period from 1979 to 2016. The large dataset allows us to provide an improved insight into the spatial and temporal distributions of the prerequisites of deep moist convection across Europe. In addition, ERA-Interim is also evaluated. ERA-Interim estimates para...

Nine meteorological stations for the measurement period of 2001-2015 were taken into account. Only SYNOP reports with a peak wind gust higher or equal to 15...
Phenology is primarily seen as an indicator of the impacts of climate change. The strongest biological signal of climatic change is revealed by phenological data from the period after 1990. Unfortunately, the Polish nationwide network of phenologi-cal monitoring was terminated in 1992, and was only reactivated in 2005. Here, we attempt to reconstru...
The aim of the study was to create and evaluate different statistical models for reconstructing and predicting selected phenological phases. This issue is of particular importance in Poland where national-wide phenological monitoring was abandoned in the middle of 1990s and the reactivated network was established in 2006. Authors decided to evaluat...
Many studies on the changes in the rhythm of nature (animate and inanimate) revealed that plants are good indicators of climate change, because they are responsive to air temperature variations.
There is a clear trend towards earlier onset of plant development in Poland, especially for spring phenological events as flowering and leafing. The main o...
This research focuses on the climatology of cloud-to-ground (CG) lightning flashes based on PERUN lightning detection network data from 2002 to 2013.

While thunderstorms in equatorial and mid-latitudes are well documented, little is known about their presence in high latitudes. There are barely a few studies on this phenomenon analyzing their occurrence in the European Arctic region. In an attempt to rectify this situation authors aim to explain which conditions are conducive to their formation...

This paper reviews two most commonly used methods of classifications of thermal conditions in Poland. Statistical analysis were performed for areally averaged values of air temperatures for months, seasons and years of the period 1951-2008 and for some geographical region of the country. Existing discrepancies between the results of the classificat...
The expansion and retreat of the ice sheet is controlled by climate changes, and from the other hand, a huge ice mass influences on the climate in the regional scale. This mechanism is commonly known as the fact but often without making reconstruction by using climatological modeling. The purpose of our study is to reconstruct the climate condition...
Questions
Question (1)
Dear All,
I would like to ask how should be the lowest vertical data interpreted if they are placed below surface level? For example, in the Alpine region with the average altitude of ~1500 m asl the vertical layers of 1000 or 975 hPa are very often significantly below the surface level (if calculation are based on geopotential height). How are those values then calculated? Is there any physical meaning of those data?
Kind regards,
