Superrotation in a Venus general circulation model
A super–rotating atmosphere with equatorial winds of ∼ 35m s is simulated using a simplified Venus General Circulation Model (GCM). The equatorial super-rotation in the model atmosphere is maintained by barotropic instabilities in the the mid–latitude jets which transport angular momentum towards the equator. The mid–latitude jets are maintained by the mean meridional circulation and the moment...
متن کاملA bulk cloud parameterization in a Venus General Circulation Model
A condensing cloud parameterization is included in a super-rotating Venus General Circulation Model. A parameterization including condensation, evaporation and sedimentation of mono-modal sulfuric acid cloud particles is described. Saturation vapor pressure of sulfuric acid vapor is used to determine cloud formation through instantaneous condensation and destruction through evaporation, while p...
متن کاملA general circulation model ensemble study of the atmospheric circulation of Venus
[1] The response of three numerical model dynamical cores to Venus‐like forcing and friction is described in this paper. Each dynamical core simulates a super‐rotating atmospheric circulation with equatorial winds of 35 ± 10 m/s, maintained by horizontally propagating eddies leaving the equatorial region and inducing a momentum convergence there. We discuss the balance between the mean circulat...
متن کاملA Study of Tracer Transports by Planetary Scale Waves in the Mit Stratospheric General Circulation Model
The quasi-geostrophic global stratospheric model at MIT developed by is used to study the zonal and time-averaged transport of potential temperature and ozone by the planetary zonal wavenumbers 1-6. Several types of covariances between the winds, geopotential, and the tracers are calculated in order to evaluate the directions and strength of the fluxes and the winds causing the fluxes. The eddy...
متن کاملConvectively Coupled Kelvin Waves in an Idealized Moist General Circulation Model
The dynamics of convectively coupled Kelvin waves and their dependence on convection scheme parameters are studied within a simplified moist general circulation model. The model consists of the primitive equations on the sphere over zonally symmetric aquaplanet, slab mixed layer ocean boundary conditions, and idealized physical parameterizations including gray radiative transfer and a simplifie...
