Moisture Changes in the Rostov Region in 1966-2019

Abstract

The results of research of variability precipitation trends in the Rostov region for the period 1966-2019 are presented. Rostov region is an important agricultural area, the distinctive feature of which is insufficient moisture. The paper considers the change in precipitation by stations located in the Rostov region. The analysis of both long-term data and for the period 2001-2019 is carried out. The support stations are located in different landscape zones: moderately arid steppe (Chertkovo), arid steppe (Matveev Kurgan, Taganrog, Rostov-on-Don, Gigant), dry steppe (Tsimlyansk), semi-desert (Remontnoe). Based on archival data, it has been established that there is a positive dynamics of changes in precipitation from 1966 to 2019 for the territory of the Rostov region. There is a dry period (2007) and a wet one (2004). The dynamics of precipitation over the year, the warm and cold period showed that a large amplitude of precipitation changes is characteristic of the summer period, while the winter period is more stable. Thus, for the territory of the Rostov region, precipitation changes are complex.
