The article provides an analysis of sinoptical conditions that caused the abnormal weather of autumn and winter 2015–2016 year in the Saratov region. The characteristic agrometeorological conditions in different soil-climatic zones of the region, showing the deviation of the air temperature and precipitation from the climatic norm and the assessment of their impact on growth, development, and overwintering of winter crops.
The article presents the results of monitoring of erosion processes on chernozems of the Volga region from 1973 to 2015. It is shown that the observed increase in winter temperatures can reduce the depth of soil freezing, increase the number of days with thaws and reduction of water reserves in the snow to the top of the snow melting. These processes improve the absorption of melt water conditions and lead to a decrease of spring runoff. In the last 30 years of flow value decreased by 3,8 times in the plowed fields, and compacted arable land – 5,7 times.
