Climate Changes in the Aral Sea Region and Central Asia

Abstract

The long-term annual, semiannual, and seasonal dynamics of the main meteorological ecosystem characteristics (total atmospheric precipitation and average, maximum, and minimum air temperature) are analyzed for the Aral Sea region and central Asia by their trends for a long-term period of 70–125 years until 2014 with the use of the diurnal records from eight meteorological stations of the WMO (the Aral Sea, Chimbai, Tamdy, Torgai, Irgiz, Samarkand, Turkestan, Chardzhou). Based on an analysis of the combined humidity- temperature regime for the long-term period, the main trends of climate changes are established, the share of variations in each meteorological characteristic is estimated by the proposed relative coefficient of variations in meteorological characteristics (RCV), and the impact of the climate changes on the ecosystems is studied.
