Numerical study of acoustic-gravity waves propagation from different ground-based sources to ionospheric altitudes
Abstract
In the report the problem of computer simulation of acoustic-gravity waves transport in atmosphere was performed. This work is the part of more general research program devoted to study of influence of earthquake's acoustic response on the ionosphere. The purpose of our simulation is to obtain distribution of values of velocity and pressure fields of wave along the trace from the source up to ionosperic altitudes (E-layer). The calculations were performed for several types of ground-based acoustic sources. The simulations were carried out for waves in nonisothermal stratified media and wind taken into account. A temperature profile was taken typical for the standard atmosphere. Results of the work are useful for preparation of active ionosphere experiments with artificial source of monochromatic infrasound waves.
