CALCULATION OF THE RESIDUAL MEAN MERIDIONAL CIRCULATION ACCORDING TO THE MIDDLE AND UPPER ATMOSPHERE MODEL
The general circulation of the middle and upper atmosphere is simulated using the middle and upper atmosphere model (MUAM) for January. Formulas for calculating the residual mean meridional circulation on the basis of wind and temperature elds obtained from MUAM are observed. The obtained distributions of the eulerian meridional mean and residual circulation are consistent with the calculations carried out earlier both on the basis of observations and model experiments. The wave contribution to the meridional circulation in the middle atmosphere can exceed 100% of the corresponding components of the mean meridional velocity, which can have a signicant impact on the meridional transport of the gas components of the atmosphere
