| Research Abstract |
Using a numerical model with a radiative transfer process approximated by the Newtonian cooling, dynamical effects on the Venus atmospheric superrotation of the thermal tides and mean meridional circulation were examined. Results show that the atmospheric superrotation is strongly suppressed by interaction among the thermal tides, mean meridional circulation, and the mean zonal flow. Next, a new radiative transfer model (RTM) applicable to the Venus atmosphere was developed by taking CO2 line shapes in the Venus lower atmosphere into account. Using this RTM, structure of the mean meridional circulation was examined.
