摘要

强风会对一个人和社会的生活条件和经济活动产生重大影响,因为它会对城市的公共经济造成破坏,摧毁建筑物,扰乱通讯和交通。本研究旨在确定2005-2020年敖德萨地区各站点强风的现代时空分布及其增强的环流和热力条件。除了Bilhorod- Dnistrovskyi外,2005-2020年敖德萨地区各站点的风速比1961-1990年的前一个气候期减弱了3.4 ~ 2.8 m/s。发现该地区南部的风势减弱最强烈。确定在大气压梯度的气旋环流中,强风主要出现在Bilhorod-Dnistrovskyi、Chornomorsk和Odesa-AMSC上空。在敖德萨地区强气流前夕,从地面到925 hPa高度以稳定的层状空气和中等风切变为主。

CIRCULATION AND THERMODYNAMIC CONDITIONS OF WIND INTENSIFICATION IN ODESA REGION
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.
