Propagation of gravity waves in the atmosphere and around critical levels
Abstract
The motion and behavior of gravity waves around critical levels, originated by a Doppler effect equaling the wave frequency and caused by background winds on the waves is treated. The motion of a gravity wave in an atmosphere with a vertical wind gradient, based on the dispersion relation of the waves, is analyzed. The critical level is treated with Taylor-Goldstein equations and the impact of viscosity and thermal conductivity around it. Observation of the waves in the ionosphere by radio signals of a navigation satellite is described.
