As a result, the stock of the soil moisture is reduced, high temperatures gradually reduce humidity, increase possible evaporation, and the threat to agricultural crops gradually increases. The drought is a very dangerous atmospheric phenomenon in reducing the productivity of agriculture, but also it is one of the processes that lead to the depletion of water resources. Thus, the study of the drought as one of the aftereffects of the contemporary warming world became one of the problems, exciting not only researchers, but the world community as a whole. In the presented article there determine distribution specifications of the drought for the last 120 years in Lenkoran, which is the one of largest economic regions of Azerbaijan
