Information on the hydrometeorological situation in river basins of Belarus formed in February 2021
In February, the average monthly air temperature was -6.5°C, which is 2.2°C below the climatic norm.
The below zero air temperature anomaly spread everywhere.
The first and second ten days of the month were very cold with average ten-day temperatures 4.4°C and 6.0°C below normal, respectively. The third decade was very warm with an average temperature of 5.5°C above normal.
In February, the amount of precipitation in Belarus averaged 38.7 mm, or 111% of the climatic norm. Excess precipitation was noted over most of the country. The largest amount of precipitation fell in the Mogilev and Gomel regions - on average 57.9 mm (175% of the climatic norm) and 55.9 mm (164% of the climatic norm), respectively, the lowest in the Vitebsk region - on average for the region 21.6 mm (54% of the climatic norm).
During the month, precipitation fell unevenly. In the first decade, excessive moisture was noted (21.9 mm or 178% of the norm per decade fell), in the second decade, the moisture regime was close to the usual (12.4 mm or 105% of the norm), in the third, there was a shortage of precipitation (4.5 mm or 41%).
In February, almost everywhere on the rivers of the country, freeze-up up to 35 cm thick was observed; in some places, ice holes were observed in the ice cover. On the reservoirs Vileyskoye, Chigirinskoye, Zaslavskoye, Soligorskoye, Krasnaya Sloboda, lakes Lukomskoye, Drivyaty, Naroch and Chervoneye, a continuous ice cover up to 40 cm thick was observed. In the third decade of February, as a result of an increase in air temperature, processes of ice destruction began on the country's water bodies.
In the first two decades of the month, slight fluctuations in water levels were noted, in the third decade, weather conditions contributed to the melting of snow and ice covers, as a result of which water levels were observed on most rivers in the country. In some parts of the rivers of the basins of the Neman, Viliya, Dnieper, Berezina, Sozh and Pripyat, the water levels exceeded the mark of water outlet to the floodplain.
By the end of February, the water content of Viliya, Zapadny Bug, Pripyat, as well as the Neman near Stolbtsy and Dnieper in the Orsha - Mogilev section was close to the usual for this time of year, the water content of the Zapadnaya Dvina, Berezina, Sozh and Dnieper in the Zhlobin - Rechitsa section was higher the norm, and less than the norm was the water content of the Neman in the Belitsa - Grodno section.
