The analysis is based on instrumental data
(temperature and rainfall) from 20 weather stations located between 1961 and
2018 on the territory of the Caucasian region. Mathematical statistics
approaches, trend analysis and the rescaled range approach have been used. The
warming trend was found to have occurred in all climate zones, accelerated
since the beginning of global warming (since 1976), although precipitation
shifts were not so unidirectional. Maximum warming (average of 0.38 ° C/10
years) in all climate zones was observed in the summer. The Hurst exponent H
(range of variance from 0 to 1) was used to examine persistence patterns, which
showed a higher trend in persistence of annual mean temperature changes (H =
0.8) relative to annual sum precipitation (H = 0.8) To = 0.64). The
precipitation and temperature spatial correlation analysis showed a rapid
decrease in the correlation of precipitation at different weather stations from
rp = 1 to rp = 0.5 on a distance scale from 0 to 200 km. A multiplicative model
of agrometeorological resources was proposed to take into account the
"slow" climate changes, during the construction of which it was
presumed that they were determined by seasonal values of average air
temperature and precipitation. Two models of agro-climatic tools are proposed,
provided the seasonal characteristics of crop cultivation (winter wheat, spring
wheat).
