Black Sea bora modeling

The development of a severe bora during the winter period near the South Coast of Crimea has been reproduced using the regional atmospheric circulation numerical model. Characteristic features of the velocity and temperature fields responsible for the formation of an intense surface current above the lee slope of a mountain range, such as internal wave breaking and air-flow blocking, have been considered. The evolution of the thermodynamic field during the severe bora development and damping, which is accompanied by a sharp decrease in the air-flow temperature, the formation of a surface jet stream, and a considerable spatial-time variability in a wide scale range, has been considered.
