Resumo
A nonlinear stationary two-dimensional theoretical model of the flow around the northwestern Caucasus mountains, taking the features of the real mountain terrain into account, is presented. The results of the calculations of the field of air-flow velocities and the general patterns of occurrence and the scale of the rotary-wave deformation of the air flow over the mountains are discussed. The model calculations are used to obtain the motion trajectories and fields of velocity perturbation in the troposphere for the real range of Lira scale values in the atmosphere. Based on the data, the safety indices of flights over the mountains in the Republic of Adygea are calculated for aircraft of two types: light and high-speed. The location of the major-hazard areas above the mountains and how they depend on the properties of the free-stream flow are determined. It is shown that, in certain parts of the area, this hazard can be critical.
