N2 - One of the important factors of atmospheric dynamics and thermal regime at heights of mesosphere-lower thermosphere is energy and momentum transfer by atmospheric planetary waves.We perform numerical modeling of the atmospheric general circulation using improved general circulation model MUAM with 56 vertical levels. This model covers altitudes from the ground to 300 km. The MUAM includes parameterization schemes of stationary planetary waves (SPWs) and normal atmospheric modes (NAMs). To parameterize NAM sources in the MUAM, additional terms to the heat balance equation are used. These terms include sets of time-dependent sinusoidal components with zonal wavenumbers 1 and 2 and periods corresponding to simulated NAMs. We perform numerical simulation of global atmospheric circulation for the initial conditions сorresponding to the years of solar cycle minima and maxima.
