| Abstract: | Height-latitude distributions of the prevailing vertical wind for the mesosphere and lower thermosphere (70–110 km) are calculated
on the basis of the empirical model of the monthly mean zonal mean prevailing horizontal wind. The presence of cellular structures
is the main feature of the obtained vertical and meridional circulations. The ways such structures form and the problems of
their modeling in global numerical models of the atmosphere are discussed. |
