Peculiarities of Variability of Regional Climate in Droughty Steppe Landscapes of Stavropol Region
The paper tackles of a study of fluctuation of basic climatic parameters on the territory of droughty steppe landscapes of Stavropol Region. The analysis of extrema and trends in long-term series of monthly averaged temperatures showed, that the gradual increase of annual mean temperatures of air is observed. The analysis of precipitation regime has revealed the presence of the steady tendency of increase of the precipitation sums in region. The calculations of De Martonn index demonstrate the humidification degree of region. The number of days with precipitation decreases, the mean diurnal amount of precipitation increased. The increase of recurrence of dusters on the north of territory and the decreasing of recurrence of dusters on the south of territory are observed.
