Comparisons between the microwave observations of wind velocities in Martian middle atmosphere and the results simulated by two Martian general circulation models (MGCMs) have been done. One MGCM has a non-LTE CO2 radiation scheme, which well reproduces daily changes of zonal wind. Meanwhile, another MGCM with a LTE CO2 radiation scheme well reproduces the retrograde wind velocities especially at a higher opacity. Neither of the MGCMs can reproduce the retrograde wind velocity in lower dust case. Brief discussions for the discrepancies between the model and observation are provided.
