Abstract

The purpose of our work is to highlight the warm character of winter 2019-2020, from the perspective of the spatial area of the Bâc river basin. The data regarding the temperature for the winter months (2019-2020) were extracted from the official website of the State Hydrometeorological Service. In order to determine the thermal characteristics, the daily temperatures of December (2019), January and February (2020) were analyzed from the four basin weather stations. The average air temperature for the winter season 2019-2020 constituted in the basin +1.6 - +3.3°С, being 4.3 - 5.4°С higher than the multiannual average and is reported for the first time during the entire observation period. According to the data of the Chişinău weather station (125 years observation period), the average air temperature for the winter 2019-2020 was +3.1°С (5.2°С higher than the norm) and placed on the 1st place in the range of years with high average temperatures for the respective season. In December 2019, the maximum air temperature rose in the basin to +18°С (December 18, Codrii Meteorological Station, Strășeni district), which in this decade is reported on average every 30 years. Very hot weather was reported in January and February (2020). Analogous winter after the thermal regime was 2006-07.
