Publishing House "UNIVERSAL"Tbilisi 2023 4In the monograph "Weather, climate and their change regularities for the conditions of Georgia" the natural factors causing the formation and variability of weather, as well as one of the important problems of modernity, climate change and causing reasons are studied in the complex manner using modern technologies. The data of the ground based hydrometeorological network and satellite observations of the Earth Observation Mission are used. The impact of climate change on the number of sectors of the country's economy (construction industry, tourism, healthcare, education and others) has been evaluated. The monograph has both scientific and practical value. The monograph is intended for specialists working in this field and the wide society. It can be used as the supplementary handbook for students of the Faculty of Natural Sciences of higher education institutions. EditorsZurab Khvedelidze -Dr. of Phys.-Math. Scie.

Results of the analysis of radar measurements of precipitation intensity (P) preceding the landslide in the vicinity of Akhaldaba (a suburb of Tbilisi, Georgia) on June 13, 2015 from 21.00 to 23.97 h are presented. In particular, the following results are obtained. Time-series of precipitation intensity under zone with the maximum radar reflectivity of the cloud has the form of a fifth power of polynomial. Time series of areas of precipitation of different intensity under the cloud were obtained and their statistical characteristics were studied. Dependence of the average intensity of precipitation under the cloud on the effective radius from the zone with the maximum radar reflectivity is obtained. Statistical characteristics of precipitation intensity over the center of the landslide top is presented. Sum of precipitation under zone with the maximum radar reflectivity of the cloud and over the center of the landslide top on 13 June 2015 from 21.00 to 23.97 h and before landslide from 21.00 to 22.45 h is assessed.

“…In general, the Tbilisi type of smog is characterized by an impossible in natural conditions feedback of the content of radon, gamma radiation and cosmic radiation with the concentration of light ions in the air, caused by the formation of secondary aerosols in an amount that, together with primary particles, is able to attach more ions to itself than their formed during ionization. It is assumed that the Tbilisi type of smog can also occur in other cities with a heavily polluted atmosphere [38][39][40][41][42].…”

Results of the detailed statistical analysis of the average monthly and annual concentrations of particulate matter PM2.5 and PM10 at three locations in Tbilisi (Kazbegi av., Tsereteli av. and Varketili) in 2017-2022 are presented. An analysis of the correlations between the indicated characteristics of air pollution has been carried out. The variability of the average annual values of PM2.5 and PM10 in the study period of observations was studied. In particular, it was found that in 2020-2021 there was a significant decrease in the average annual concentration of aerosols due to restrictions on the movement of vehicles associated with the covid-19 pandemic. It is noted that for the entire observation period, the average annual concentration of PM2.5 and PM10 was above the permissible norm.
