Abstract: Dry wind in modern climate is an actual problem in Ukraine because it occurs almost
every year during the vegetation period. We studied the spatial and temporal distribution
of dry winds, their meteorological characteristics, dynamics of development and circulation
processes leading to their formation in Ukraine. In this paper we described the features of
temporal distribution of the hot dry winds over Ukraine from April to August, for the period
of 1995Σ2015 as well as interannual variability of dry winds. The analysis of the atmospheric
circulation conditions was carried out using the classification of elementary circulation mechanisms
(ECM) of the Northern Hemisphere, which was developed by Dzerdzeevsky (1968).
The most repetitive of ECMs in the period of dry wind were identified, which are characterized
by a formation of anticyclone periphery processes over the territory of Ukraine.
Key words: dry wind, elementary circulation mechanisms, atmospheric circulation, macrocirculation
processes
