Trends of Heat Supply of Agricultural Crops in the Conditions of Changing Climate on the Territory of Armenia for the Period from 1993 to 2019

Abstract
The article considers the heat supply of agricultural crops measured by the sum of average daily air temperatures exceeding 10°C on the territory of the Ararat valley and its foothill area. The patterns of fluctuations of heat supply were studied. Daily observations data of 9 meteorological stations of the studied area were used. It is revealed that on the territory under consideration the heat supply is distributed unevenly and decreases with altitude, varying from 4468 to 2971°С with a vertical gradient of 174°С/100 m. There is a trend to increase heat supply on average by 380°С from 1993 to 2019 years. Heat supply conditions of the region are favorable for the growth and development of heat-loving and drought-resistant varieties of agricultural crops.
