Frequency of occurrence and dynamics of droughts in Eastern Georgia in the 20th century

Abstract

Frequency of occurrence and dynamics of droughts in 20th century were studied based on the observational materials of 20 meteorological stations of Eastern Georgia. The periods with precipitation deficit were studied against the background of high temperatures. The drought intensity was assessed with the Selyaninov hydrothermal coefficient.

Ongoing climatic change in Northern Eurasia: justification for expedient research

“…The pattern of ongoing global warming (stronger warming in high latitudes compared to the tropics) gradually reduces these gradients and this process has accelerated in recent decades (figure 4). As a result, we have already witnessed a gradual increase in the frequency and extent of dry conditions and forest fire risk across Northern Asia (Mescherskaya and Blazhevich 1997, Zhai et al 2004, Soja et al 2007, Elizbarashvili et al 2009.…”
