The propagation of internal gravity waves (IGWs) of orographic origin into the atmosphere plays an important role in the formation of the dynamic and thermal regime of the atmosphere. Models of global atmospheric circulation with a relatively low resolution (100 km and more) are not capable of directly reproducing IGWs; therefore, to describe reasonably the accelerations and heat inflows created by dissipating IGWs in the atmosphere, various parameterization schemes or setting their sources are used. In this study, polarization relations for mesoscale stationary orographic gravity waves (OGWs) are refined taking into account the Earth's rotation and new equations are obtained for calculating the vertical profiles of OGW amplitudes, wave accelerations, and heat influxes. Based on the new equations, a new scheme for parameterization of the subgrid-scale dynamic and thermal effects of OGW was developed to be included in global atmospheric circulation models.
