Variability of the Mean Max Annual Air Temperature in 39 Locations of Georgia in 1956-2015

Abstract

The research results of the variability of the mean max annual air temperature at 39 locations in Georgia against the background of global climate change in 1956-2015 are presented. The statistical characteristics of the mean max annual air temperature in the period 1956-2015 (T), 1956-1985 (T₁) and 1986-2015 (T₂) for each point were studied. It has been established that in the second period compared to the first, there is a significant increase in the average max air temperature at the 29 stations from 0.3˚С (Stepantsminda) to 1.2˚С (Bakuriani); for Shovi this difference is 1.1˚С. It is shown that between the T₁, T₂ values and the terrain height there has been observed the high inverse linear correlation and regression relationship there. At the same time, the lines of the regression equations are parallel with the increasing in the second period compared to the first by 0.6 ˚С. It is shown, that a significant value of (T₂- T₁)/T changes from 2.0 % (Chokhatauri) to 11.0% (Bakuriani); for Shovi this indicator is 8.4 %. The significant value (T₂- T₁)/T increases with terrain height in accordance with a second power polynomial.
