Brașov is the largest city in the Romanian Carpathians, being located inside the largest low-lying area in the country and exposed to western climatic influences, with well-defined local features, especially in the cold season, when many thermal extremes may occur. The main objective of this study was to analyze the minimum air temperatures and hig...

... following degree-days (DDs) indices (Figure 8) are also very important regarding the amount of energy required to heat or to cool homes. Generically, they represent the sum of all daily minimum air-temperature values less than 0°C (HDDn0) and/or than 10°C (HDDn10) from each year analyzed. ...

... inter-annual variation of heating degree days (HDDs) shows that 1985 was the coldest year from the entire analyzed period (1,318.9°C for the HDDn0 index, respectively 3,504.4°C for the HDDn10 index), and the warmest years were both 2014 and 2015 (with 521°C for HDDn0 index, respectively 2,478.4°C for HDDn10 index), as represented in Figure 8-A. Thus, in 1985, more energy from power plants was needed A B ...

... each case, these indices showed a significant decrease over time, especially for the HDDn10 index, pointing to a gradual increasing of the minimum air-temperatures over the analyzed period. The trend for HDDn0 index is decreasing from a value around 1,000°C to only an average value of 700°C, as showed in Figure 8-B. The trend for HDDn10 index is decreasing even more pronouncedly, from a value closer to 3,200°C to almost 2,700°C (Figure 8-C). ...

The trend for HDDn10 index is decreasing even more pronouncedly, from a value closer to 3,200°C to almost 2,700°C (Figure 8-C). The main cause of both these trends is most probably the general ongoing climate warming process, which attenuates the normal climatic cooling effects, especially in the cold season of the year. ...

The manuscript addresses the problem areas of the educational migration environment in the oblasts of the Carpathian region and the main directions of their regulation. The educational migration environment is examined across main components: educational migration capacity (characterizes educational and informational conditions); academic environme...
Parna apicalis (Brischke, 1888) is described as new to the Carpathian Basin and Hungary and Hinatara recta (G.C Thomson, 1871) represents the first record in over 100 years in Hungary.
In the last decade, coniferous stands outside their natural range in Romania have experienced declines in both their health and growth and, in tandem with global climate trends, these forests are becoming even more threatened. We studied the relationship between tree growth and defoliation as an indicator of tree health. The data came from black pi...

... In the context of the ongoing climate changes, the energy consumption has become a topic of utmost concern, especially that the inhabitants of big cities are trying to find more cost-effective ways and resources for economical indoor-heating (Gabril, 2014;Ionac et al., 2012) provided that the frequency and intensity of climatic extremes and hazards are increasing (Ionac et al., 2023;Ilea and Ionac, 2022). ...
The energy consumption has become a real concern in choosing the most cost- effective way and resources for indoor-heating. This experimental study tried to estimate both the energy amounts needed to heat up the residential indoor spaces and the resulting average costs that people living in the Bucharest Metropolitan Area might have to pay for heating during the winter months. The daily minimum air-temperatures, incoming solar radiation and wind- speed values provided by the Bucharest-Băneasa weather station were used to calculate the corresponding mean monthly values of an expressive compound index for December, January and February, over the 1980-2015 period. In this respect, the Cooling Energy Consumption (CEC) index has been calculated. Then, its values were related to two different types of individual heating systems (CT): a conventional CT produced by Ariston (net efficiency of 93%) and a gaseous condensation CT produced by Viessmann (net efficiency of 108%). Finally, the results were multiplied by the actual unit cost of energy in Romania (1.3 lei/kWh), provided that the total monthly consumption of electricity per household keeps less than 300 kWh/month, so that some interesting and realistic estimates of heating expenditures could be obtained for either each or all winter months in Bucharest – Romania’s capital city. This method might be useful both to local authorities and inhabitants to estimate and plan in advance their public or domestic budget to more economically sustain their energy resources and expenditures.
Thermal Profile of a Carpathian Cold-Air Pool: Teșnița Valley from Dorna Depression. The present paper explores the thermal environment close to Poiana Stampei weather station using hourly data, collected during one full calendar year. The data was gathered by using professional air temperature data logger installed in a standardized weather shelter in the Teșnița Valley, located 1.2 km east from the official weather station, at 885 m. The monitored area is subject of strong air temperature inversions, which constitute the main explanation for an annual air temperature of 6.7°C, 1°C lower than at the nearby official weather station. This cold-air pool reached at hourly level an intensity of 11.7°C, which is impressive for an altitudinal difference of only 32 m. A description of the features of this cold-air pool is presented based on these in-situ measurements and also using some relevant mobile measurements during specific synoptic conditions. Moreover, synoptic conditions favorable for the cold-air development were also analyzed.
