The article analyzes the change of climate parameters in arid zone according to the weather stations and mediopunto Astrakhan region for 1946-2015. and weather stations for Astrakhan 1922-2015 he Identified the increase in air temperature. The average rate of growth is on average 0.2°C / 10 years in the region. The most significant increase in average temperatures observed in the cold season (an average of 1.2 °C every 30 years). Changes in precipitation in the region is cyclical in nature with a slight decrease the last 15 years. The most noticeable seasonal changes in precipitation.
