【 摘 要 】

In the last 50 years the wind characteristics in Western Ukraine have been noticed to undergo changes in addition to temperature and precipitation regimes. Regions with complex topography are considered to be the territories that are the most susceptible to the global climate dynamics. The Middle Dniester Valley region as an area with the most complicated field of wind patterns is researched in this article. It identifies a number of spatial and temporal peculiarities of the wind regime within the valley. The intensification of thermal valley circulation is detected. Some degradation of eastern winds in the annual roses is detected that is well correlated with the evolution of barometric systems over the North Atlantic European sector.
