Changeability of Maximally Possible and Total Evaporation on Territory of Saratov Area in the Conditions of Changing Climate

To the article the estimation of dynamic of annual precipitation is driven, maximally possible and total evaporation in the different soil-climatic zones of the Saratov area in the conditions of the global warming of climate. It is shown that in a period from 1981 to 2014 year noted a statistically significant increase in the maximum possible evaporation, which leads to an increase of deficit of evaporation. As a result of the observed tendencies the climate norms of gidromelioration in the area were increased on 200–300 м3 / hectare.
