THE REACTION OF THE SEMI-DESERT LANDSCAPES OF PRIMORSKAYA LOWLAND OF DAGESTAN ON MODERN CLIMATIC CHANGES

Aims. The authors of the article analyze climatic conditions in semidesert landscapes of Primorskaya lowland of Dagestan for 18822012. There were also analyzed changes in these parameters over decades, in general, the contribution of certain seasons and months in annual temperature and precipitation change is revealed.Location. Primorskaya lowland of Dagestan. Methods. By means of methods of mathematical statistics there were analyzed changes in average annual air tem perature and amount of precipitation as well as gross moisture conditions of active vegetation period (the coefficient of moisture).Results. The analysis leads to the conclusion that unidirectional trends in temperature and precipitation (for exam ple, the increase of air temperature or amount of precipitation) are relatively rare; there are more often observed 23 years multidirectional fluctuations of climatic parameters. Main conclusions. In general, despite a maximum warming of the last decade (20012010), the threshold values of climatic parameters (for example, amount of precipitation and coefficient of moisture) remain within those values that were noted for the reviewed 130 years. As a result this climatic variability is considered as a characteristic feature of semidesert landscapes of Primorskaya lowland of Dagestan.
