A climate change workshop for the Middle East brought together scientists and data region to produce first area‐wide analysis of extremes region. This paper reports trends in extreme precipitation temperature indices that were computed during additional became available after workshop. Trends these examined 1950–2003 at 52 stations covering 15 countries, including Armenia, Azerbaijan, Bahrain, Cyprus, Georgia, Iran, Iraq, Israel, Jordan, Kuwait, Oman, Qatar, Saudi Arabia, Syria, Turkey....
In the monograph "Weather, climate and their change regularities for conditions of Georgia" natural factors causing formation variability weather, as well one important problems modernity, reasons are studied in complex manner using modern technologies. The data ground based hydrometeorological network satellite observations Earth Observation Mission used. impact on number sectors country's economy (construction industry, tourism, healthcare, educationand others) has been evaluated. both...
Georgian Climate change has been considered comprehensively, taking into account World Meteorological Organization recommendations and recent observation data. On the basis of mean temperature precipitation decadal trend geo-information maps for 1936–2012 years period, territory zoning carried out each areas climate indices main trends have studied, that best characterize - cold hot days, tropical nights, vegetation period duration, diurnal maximum precipitation, five-day total intensity...
Based on the materials of observation 50 meteorological stations Georgia for period between 1936-2013, research has been made geography, structure, intensity, duration and dynamics tropical nights Georgian territory. Nights are considered if minimum air temperature is above 20°C (TR20). Tropical most widespread in intermountain trough – Kolkheti lowland, plains Central Lower Kartli, Alazani valley, where average number during one year reaches 35. With growth altitude, naturally decreases,...
The scope of this work is to study some aspects the formation regional climate Caucasus (with a specific focus on Georgia) against background impact mineral aerosols using modelling (the RegCM interactively coupled with dust module, WRF-Chem, and HYSPLIT models) satellite data (MODIS, CALIPSO). annual mean, as well error in summer winter temperatures, standard deviation correlation coefficient compared CRU were calculated for 8 sub-regions different orographic properties. calculation results...
The effect of the dust on climate in Caucasus region, with a specific focus Georgia, was investigated Regional Climate Model RegCM interactively coupled model. For this purpose we have executed sets 30 years simulations (1985–2014) and without effects by RegCM4.7 model 16.7 km resolution over domain 50 encompassing most Sahara, Middle East, Great adjacent regions. Results calculations shown that aerosol is an active player system Georgia. Mineral influences temperature optical depth spatial...

WRF model have been tuned and tested over Georgia’s territory for years. First time in Georgia theprocess of data assimilation Numerical weather prediction is developing. This work presents how forecasterror statistics appear the problem through background error covariance matrix – B, wherethe variances correlations associated with forecasts are estimated. Results modeling backgrounderror control variables using desired domain configurationare discussed presented. The was implemented two...
Abstract Under the increase of concern for food security in world, mainly caused by water resources shortages, forecast and determination crop yield at regional scale has been considered as a strategic topic. This study conducted to assess possible impacts climate change on cereal crops productivity irrigation requirement two main producing regions Georgia, according current pattern, 2050s periods. With this aim, water-driven FAO-AquaCrop model used. Furthermore, ongoing forecasted changes,...
