dc.description.abstractSome results of a study of the variability of the average annual air temperature in Tbilisi against the background of global warming in 1880-2021 are presented. For the analysis, data of the National Environment Agency of Georgia (http://www.pogodaiklimat.ru/) and the NASA Goddard Institute for Space Studies (https://data.giss.nasa.gov/gistemp/) are used. A comparison of data on the variability of the anomalies of the average annual air temperature in Tbilisi in relation to the average temperature in 1951-1980 (T:TB) with similar anomalies of the global air temperature over land and ocean (T:GL), air temperature in the northern hemisphere (T:NH), and zonal air temperature in the northern hemisphere in different latitude ranges (T:24°N-44°N, T:24°N-64°N, T:44°N-64°N and T:64°N-90°N) are conducted. In particular, the following results are obtained. Mean value of T:TB in 1880-2021 is 0.05°C and best match to mean value of T:GL (0.06°C). Max value of T:TB is 2.26 °C and best match to max value of T:44°N-64°N (1.82 °C). Min value of T:TB is -1.70 °C and best match to min value of T:64°N-90°N (-1.76 °C). Coefficient of linear correlation of T:TB with others investigation parameters change from 0.51 (with T:64°N-90°N) to 0.67 (with T:24°N-44°N). Difference between mean values T:TB in 1992÷2021 and 1880÷1909 is 1.2 °C and exactly coincides with the analogous difference for T:24°N-64°N. The trends of all studied parameters are satisfactorily described by a fourth power polynomial. For Tbilisi, a linear approximation is also acceptable.ka_GE
