The main factors of the process of occurrence of climatic risk of dangerous meteorological phenomena are considered. The article describes a methodology for assessing the vulnerability of objects (risk recipients) exposed to hazardous phenomena. On the example of two points located in different geographical conditions - Tbilisi and Dmanisi, possible social and economic risks associated with these phenomena are identified. The greatest climatic danger is represented by fog and strong winds, and in summer, Tbilisi is very hot with concomitant soil, atmospheric drought, and extreme fire hazards. To a lesser extent, the area is damaged by heavy rainfall and hail

Nights are considered tropical if minimum air temperature is above 20°C (TR20). Tropical nights are most widespread in the intermountain trough – Kolkheti lowland, the plains of Central and Lower Kartli, Alazani valley, where the average number of tropical nights during one year reaches 35. With the growth of altitude, the number of tropical nights naturally decreases, and on the height of 1000m there are no tropical nights detected. As a result of global warming the increase in the number of tropical nights has been most notable on the Black Sea coast and in the region of the nearby Kolkheti lowland (4-6 days per decade). In the internal regions of the lowland and in the Eastern Georgia the rate of change decreases. On the Black Sea coast tropica...

The geoinformation map was constructed for the number of tropical nights for the WMO base period. The periods of occurrence and return of their different gradations and the regularities of long-term variations are revealed.

The author constructs geoinformation maps for the spatial structure and explores the dynamics of these indices for the period of global warming, assesses the possible risks of the development of adverse climate conditions (high waters, floods, droughts, desertification). The obtained findings can be used in the summation of corresponding indices for the Caucasus region, the Black Sea area, and Western Asia.

The obtained datasets characterize the real picture of the spatial distribution of temperature and precipitation on the territory of Georgia; therefore, they are used for working out geoinformative maps of temperature and precipitation variations. Revealed are the areas and centers with different intensity of warming and cooling. It is found that the annual temperature and total annual precipitation averaged for the territory do not vary considerably under conditions of the global warming.

Determined are the number of days and the duration of hurricane winds in different regions of the country. Studied are the empirical functions of their distribution and the areal limits.

The contribution of dangerous fogs to the total number of foggy days is estimated. The number of days with dangerous fogs and their duration in different regions of the country are determined and the empirical functions of their distribution, sizes of areas of their expansion, temperature regime, and peculiarities of annual variations are studied.

Plotted are the geographic information maps of the spatial structure of temperature variation rate.
