Abstract
To provide the more accurate simulation of stationary planetary waves and atmospheric tides using the middle and upper atmosphere model (MUAM), the three-dimensional (longitude-latitude-height) semi-empirical climate model of water vapor distribution in the troposphere was developed which takes into account seasonal variations. The modules of radiation heating and cooling in the MUAM model were modified taking into account the dependence of water vapor concentration on longitude. The simulations performed using the modified version of MUAM revealed that the consideration of water vapor concentration variability along the circle of latitude leads to the substantial dependence of solar heating on longitude that affects the amplitudes of stationary planetary waves in the stratosphere.
