Abstract

A new universal mechanism of the formation of long-lived atmospheric vortex is proposed. It is based on the hydrodynamic pressure drop in the air stream, if air density decreases in the flow direction. The magnitude of this drop may increase with jet velocity increasing. It is assumed that jet, linking the atmospheric layers with different air density, may have a local area of low pressure which can generate the vortex. The possible conditions for the emergence and intensification of atmospheric vortices of various types are discussed.
