Abstract

The response of the atmosphere to a harmonic source of a vertical impulse moving along the Earth surface is investigated. It is shown that a small amplitude source can result in two appreciable nonlinear effects: flow formation and changing of an atmosphere temperature. The flow is an especially considerable effect. An ion-neutral friction is not taken into account; therefore, the effects obtained can be a little bit overstated. At increasing of the source amplitude, at the heights 100 - 200 km some irregular oscillations arise due to wave disintegration into disturbances of smaller scales. The scales of these disturbances are of the one order with the grid steps; therefore, it is possible to study them only with a finer grid.
