Climatic changes in European Russia and the Republic of Belarus in the XX-XXI centuries under the influence of atmospheric circulation

Abstract Climatic changes in the atmosphere from Earth’s level to altitude of 80 km Russia and Republic Belarus (RB) are considered using data 1251 stations RIHMI-WDC (1976-2019), ERA5 reanalysis (1979-2019), 99 long-row located European part (ER) (RB). An analysis constructed trends air temperature (AT) atmospheric precipitation is made assess spatial temporal variability thermal humidity regimes territory. Some differences rates warming between winter summer seasons, troposphere stratosphere revealed. Near earth's surface, rate maximum polar latitudes; cools more strongly than one. To influence circulation on ER RB, correlation coefficients AT indices AO, NAO, SCAND, EAWR calculated. Using a low-pass Potter filter, 40-year periodicity fluctuations RB November In stratosphere, relationship zone Arctic oscillation index found. The spring restructuring stratospheric occurs with delay if strong sudden warmings (SSW) occur winter.
