Atmospheric Disturbances in the Mountain Flow and the Problem of Flight Safety in the Mountains of the Republic of Adygea

This chapter considers airflow around mountain systems as a mesoscale atmospheric phenomenon. It presents a nonlinear stationary dimensional theoretical model of the airflow of the Northwest Caucasus Mountains, taking into account characteristics of a real mountain terrain. The chapter further discusses the results of the calculations of the speed field of the airflow and general regularities of the origin and the scale of the rotary-wave deformation of the airflow over the mountains. The flow over the mountain greatly smoothed, and the rotor area completely disappeared. Flight safety indicators over the mountains of the Republic of Adygea for two types of aircrafts (light-engine and speed) were calculated on the basis of the obtained data. In certain conditions, flights for both high-speed and single-engine aircrafts can be considered dangerous.
