CIRCULATION AND THERMODYNAMIC CONDITIONS OF WIND INTENSIFICATION IN ODESA REGION

Abstract

A strong wind significantly affects the living conditions and economic activity of a person and society, because it can cause damage to the communal economy of cities, destroy buildings, and disrupt communication and transport. This research is devoted to the determination of the modern spatiotemporal distribution of strong wind at the stations of the Odesa region for 2005–2020, as well as the circulation and thermodynamic conditions of its strengthening. Revealed the weakening of the wind speed from 3,4 to 2,8 m/s at the stations of the Odesa region for 2005-2020 compared to the previous climatic period of 1961-1990, with the exception of Bilhorod- Dnistrovskyi. Found the intensity of the wind regime decreased most strongly in the south of the region. Determined that strong winds arose mainly over Bilhorod-Dnistrovskyi, Chornomorsk, and Odesa-AMSC during cyclonic circulation with large baric gradients. Revealed the predominance of stable stratified air with moderate wind shear from the surface to the level of 925 hPa on the eve of the strong wind in the Odesa region.
