A database of average monthly air temperat ure and atmospheric precipitation has been created for seven meteorological stations for the period between 1936 and 2009. It was used to study current trends of climate change in the Kazbegi area, a mountain region in the Greater Caucasus. Changes in temper ature and precipitation are described by circular regression equations and rates of these changes are identified.

To study the distribution and repetition of droughts, an ar chive of droughts has been created in eastern Georgia for 19 meteorol ogical stations for the vegetation period between 1961 and 2008. It has been eval uated geographic and meteorological conditions of droughts formation: conditions of humidity, temperature background, hydrothermal regime of soils. It has been studied the territorial distribution and probability of dry months, repetition of drought s within a season and a month, severe and ultra-severe dr...

The current climate change regulations have been investigated based on the data of 90 meteorological stations of Georgia from 1906 to 2005. It was revealed that the climate change has the mosaic character: arid landscapes became warm more quickly than humid ones, which were even cooled in many cases. The dynamics of recurrence of anomalous deviations of monthly average temperatures have been investigated.

As traditional organic fuel resources are being depleted in the modern world, energy crisis and environmental situation aggravate and the attention of the mankind is increasingly drawn towards untraditional, renewable sources of energy and opportunities of their efficient use. Georgia has significant geothermal resources concentrated in numerous thermal springs and basins. There are two main basins of thermal waters in Georgia. The water in the Kolkheti basin is distinguished for its low mineralization, it is over...

There are presented results of periodic measurements of radioactive gas - radon content in sea, river and drinking water in resort zone Ureki-Shekvetili at the Black Sea coast of Georgia during the period from September, 2008 till October, 2009. It is shown, that the level of radon content ranges in interval 0.12 – 0.44 Bq/L in sea water, 0.15 - 0.58 Bq/L and 0.13 – 0.59 Bq/L in river water for river Natanebi and river Supsa, accordingly, 7.9 – 14.0 Bq/L and 1.19 – 4.35 Bq/L in drinking tap and artesian wa...
