Numerical Modeling of the General Circulation of the Earth’s Lower and Middle Atmosphere in Mid-January

Results are presented from modeling the general circulation of the Earth’s atmosphere in the 0 to 80 km range of altitudes in mid-January usinf a non-hydrostatic model. The field of solar and thermal radiation is calculated with high accuracy in the model. The model reproduces surface cells of vertical meridional circulation over oceans, large-scale vortices, mountain leeward waves, the rise of the tropopause over the winter polar region, and circumpolar vortices and warming in the upper stratosphere and lower mesosphere in the polar region of a winter hemisphere.
