Gas-Dynamic General Circulation Model of the Lower and Middle Atmosphere of the Earth

Abstract

This paper presents a brief description of the General Circulation Model of the lower and middle atmosphere of the Earth, which is designed to study atmospheric dynamics in a wide range of spatial-temporal scales. The model is based on numerical integration of the complete system of equations that describe the dynamics of a viscous atmospheric gas using a spatial grid with a high resolution. The model takes into account the surface relief and the presence of atmosphere aerosols in the form of microdroplets of water ice particles, as well as the phase transitions of water vapor to aerosol particles and back.
