Analysis of Trends in Aridity Changes for the Southern Ural Region over the Period 1960–2019 Using Various Methods

A statistical analysis of extreme episodes of aridity and humidity for the territory of the Southern Urals was performed. The calculations were based on the average daily air temperature and daily precipitation from 11 stations over the period 1960–2019. The spatial temporal characteristics of the summer droughts were studied on the basis of the station observations and calculated quantitative parameters. It has been established that the frequency of droughts in the Southern Ural region has increased over the past 19 years, the spread of the phenomenon reaches its peak in July.
