Abstract
Using the WRF-ARW model, we have conducted a numerical simulation of the atmospheric circulation in the Crimean region for a 30-day period in the summer. The characteristic features of the velocity fields of breeze circulation over Crimea have been identified. We have reproduced the specific features of the development of breeze as a gravity flow, such as the direct and indirect circulation cells, wave oscillations on the boundary between them associated with the Kelvin–Helmholtz instability, and the formation of the breeze head. The breeze velocities and their diurnal cycle have been estimated. For mountainous regions of the southern coast of Crimea (SCC), we have shown that the coastal circulation is predominantly contributed by quasi-diurnal oscillations associated with the wind excitation on the mountain slopes. The physical conditions for the development of a strong katabatic wind have been considered. The counter breeze flows in eastern Crimea formed under the influence of the adjacent Black and Azov seas generate an intense air rise in the meeting zone. The related linear cloudiness area is clearly traced on satellite images. We have obtained daily hodographs of breeze circulation reflecting the local conditions of the shoreline and the configuration of coastal mountains.
