MECHANISM OF THE APPEARANCE OF A LARGE-SCALE VORTEX IN THE TROPOSPHERE ABOVE A NONUNIFORMLY HEATED SURFACE

Abstract

This paper is dedicated to a numerical modeling study of the formation mechanisms of a large-scale vortex over a warm water band on the ocean surface. For this purpose, we developed a 3D model of the atmospheric circulation in a domain, which is a part of spherical layer over a limited region of the Earth’s surface (altitude 15 km, longitude and latitude 12°). This model takes into account heating/cooling of the air due to absorption/emission of infrared radiation, as well as due to phase transitions of water vapor to microdrops of water and ice particles, which play an important role.
