A superrotation is simulated in a T10L100 general circulation model for Venus' middle atmosphere (VMAGCM), in which the radiative effects of aerosols are calculated. The simulation in a domain of 30-100 km is conducted under the condition of a bottom zonal flow with a velocity of 50 m s-1 at the equator. Thermal tides contribute to the maintenance of the cloud-top superrotation together with meridional circulation and vertically propagating gravity waves. The meridional circulation and wave activity are sensitive to the vertical eddy diffusion. Although the equatorial zonal flow has a velocity of about 70 m s-1 when the vertical eddy diffusion coefficient (KV) is set at 5.0 m s-2, it has a velocity of >100 m s-1 when KV = 2.5 m s-2. The fully developed equatorial jet for the small KV case is enhanced at 65 km by small-scale gravity waves emitted from the cloud top.
