Study of the Mean and Extreme Values, Intensity and Recurrence Variability of Meteorological Elements Based on the 1956-2015 Observation Data

Abstract

Based on the data of the last 60 years (1956-2015) of 39 stations of the Georgian Meteorological Network, the nature of the change in the intensity and recurrence of the mean and extreme values ​​of the meteorological elements was studied. The mentioned 39 stations were selected in order to optimally take into account the climatic features of the territory of Georgia. The trends of temperature and precipitation were evaluated. For the indices (35 indices) the change trends according to the average annual value were studied. The R-based software package ClimPact2 was used to calculate the sector climate indexes. The R-based software RHtestV4 and RHtests_dlyPrcp4 were used to check the homogeneity of the discussed time series
