Abstract
Forecasting of possible locations, intensity, vertical and horizontal propagation of mountain waves (MW) is one of the main problems to ensure flight safety. This is very important in the complete absence predictions’ methods on the territory of Russia in generally and, especially, in Far-Eastern region. Main problem of the MW forecasting is almost complete absence of MW observations and instrumental measurement of their characteristics. In the article, approach to conformity assessment of simulated MW parameters (location, intensity, vertical and horizontal propagation) to real characteristics which are approximately determined by satellite images of lenticular clouds (Sc и Ac lenticularis) and atmospheric sounding is presented. It is shown that characteristics of simulated MW by the Weather Research and Forecasting model with grid spacing of 1 km are close to actual values. Possibilities to calibrate parameters of simulated MW calculated on the 5-km grid by values obtained on 1-km grid are discussed.
