DYNAMICS OF WEATHER CONDITIONS IN KURSK REGION OVER THE LAST 50 YEARS
Monitoring of weather conditions in the study area was carried out over a fifty-year period according to the data of the agrometeorological post located in the village "Petrin" of the Kursk region. It was found that for the period from 1968 to 2017, the average annual air temperature increased by 0.6 ° С compared to the average long-term norm and amounted to 6.3 ° С. On average, over a fifty-year period, the spring and summer months were 0.3-1.3 ° C warmer than the norm, and the autumn months were 0.3-0.7 ° C cooler. The winter months became much warmer: - December by 0.6 ° С, January by 3.3 ° С and February by 1.1 ° С. The reason for such changes in the temperature regime is the recent change in the nature of atmospheric circulation. Over a fifty-year period of 26 years, or 52%, the average daily temperature of the growing season was close to the average long-term norm, 15 years or 30% of the years, the average daily air temperature exceeded the average long-term norm. Over a half-century period, 30 years or 60% fall on years, with the sum of annual precipitation close to the value of the average long-term norm. Fifteen years from fifty - 30% were wet for years. In 10% of years from 50 years of observations, the amount of annual atmospheric precipitation was 55-96 mm lower than the sum of the multi-year norm. Considering the amount of precipitation by months, over the past 20 years, we can note a significant decrease in comparison with the average 50-year period. The average precipitation in May, June, July and August over the past 20 years has dropped below the average annual values (by 12-17%). Over a 50-year period, the SCC varied from 0.5 (2010) to 2.2 (1973). Having built a linear trend of changes in the SCC, we note a decrease in the indicator over the years. Thus, the analysis of the meteorological conditions of the study area over a fifty-year period indicates a steady trend towards warming.
