Characterizing the temperature and humidity regime of the Left Bank of the Saratov region against the background of the second wave of global warming

Abstract

The article considers the temperature and humidity regime of the Left Bank of the Saratov region in various natural climatic periods of the state of the earth’s climate system – the first wave of global warming, stabilization, the second wave of global warming. It is noted that against the background of rising temperatures from one climatic period to another in the Trans-Volga region, the amount of precipitation in the cold half of the year increases. The trend in precipitation during the warm period is ambiguous. Against the background of the second wave of global warming, at two of the studied stations, an increase in the amount of precipitation during the warm half of the year is observed, and at the other two ones a decrease occurs. Calculation of hydrothermal coefficients revealed a trend of increasing the degree of aridity in the Left Bank of the Saratov region. The authors conclude that there is an increase in hydrometeorological risks of crop cultivation in this area.
