POSITIVE DECADE TEMPERATURES ON CULTIVATED LANDS IN DRY-STEPPE ZONE OF CENTRAL PRE-CAUCASIAN REGION ON THE TERRITORY OF THE REPUBLIC OF NORTH OSSETIA?ALANIA ACCORDING TO WORLD METEOROLOGICAL ORGANIZATION (WMO) PERIODS

In the article the results of analysis of multiyear sum series of positive temperatures at Mozdok meteorological station (37145WMO index) are presented according to decade periods. The values for WMO periods of 1961-1990 (climatic normals) and of 1991-2014 (climatic shifts) are calculated. The meteorological station is located in the central part of the studied region (dry-steppe zone of Central Pre-Caucasian region) at height of 135 m above sea level. The analysis of decade values dynamics for sums of positive temperatures for WMO post-basic period of 1991-2014 is made compared with calculated climatic normals of 1961-1990 of various limits. A significant increase in thermo-resources of 1991-2014 decade periods is detected, which predetermines the increase of productional potential of agricultural crops in the region.
