It is determined that the waves in the atmosphere are air vibrations that propagate in the Earth's atmosphere, arise under the influence of external forces and occur involuntarily, in themselves, because the Earth's atmosphere has its frequencies. It is established that the physical nature of these forces influences the formation of three classes of waves in the atmosphere, among which are acoustic (sound), internal gravitational and planetary. It is shown that in the lower sphere of the atmosphere, as a rule, wave sources are located, which, nevertheless, can not only be in the lower atmosphere, but also penetrate into other layers. It was found that acoustic waves are characterized by compressibility of air, and the distribution velocity is approximately 300 m / s. It is noted that the pressure is insignificant (1...10 Pa), with the exception of waves that occur during explosions. The argument is made that the study of atmospheric physics is quite an urgent issue, since it allows solving environmental, climatological issues. It is noted that the analysis of wave changes in the atmosphere requires a detailed analysis of large data sets and long time series. The main goal of the work was to simulate orographic waves using the WRF model with high resolution. To achieve this goal and study the wave changes, the authors used models with high expansion, since it is with the help of experiment that one can study in detail the problems posed. It is established that the waves are located at altitudes from the surface to a level of 800 mb (about 1900 m). It is concluded that this wave track in the clouds of the lower tier of the atmosphere above the sea appeared as a result of the formation of a specific wind speed profile |
