Abstract: | Regular features of motion of thermics in a stratified atmosphere are considered. Thermics are single and multiple free volumes of floating gas, which successively arise with a certain frequency near a horizontal surface. In a real atmosphere, large-scale thermics of this type appear, for example, as a result of powerful pulse actions on the ambient medium that are successively produced at one point near the Earth surface.
