Research on dynamics of the athmospheric precipitation sums in the mountain part of the Karachay-Cherkess republic from 1961 to 2015

The dynamics of the time series of atmospheric precipitation sums average in a year and on calendar seasons in a mountain zone of the Karachay-Cherkess Republic from the 60th of last century to 2015 is investigated. It is established that none of the trends identified possesses the signs of stability and statistical significance for the series of annual and seasonal precipitation both for the period 1961-2015 and for 1976-2015.
