Features of agrometeorological conditions in the Turkestan region

Abstract

The trends of changes in agrometeorological indicators in the Turkestan region for the period from 1991 to 2022 are analyzed. There is a tendency to increase the sums of air temperature for the growing season, a tendency to decrease the sums of precipitation for the growing season, a tendency to decrease the values of the humidification coefficient K and the drought index HTC. Such conditions imply an increase in the heat supply of the growing season, an increase in the number of hot days, a decrease in humidification and an increase in the aridity of the growing season. Years with favorable weather conditions have a repeatability of 30% in the mountainous semi-desert zone. Years with satisfactory weather conditions have a repeatability of 20% in the mountainous semi-desert zone and 10% in the mountainous desert zone. Years with adverse weather conditions have a repeatability of 100% in the desert zone, 90% in the mountainous desert zone and 50% in the mountainous semi-desert zone.
