A simple expression for vertical convective fluxes in planetary atmospheres
We explore the vertical convective flux Fc in a radiative-convective grey atmosphere. An expression of the form Fc = Fsτo/(C +Dτo) appears useful, where Fs is the shortwave flux absorbed at the base of an atmosphere with longwave optical depth τo and C and D are constants. We find excellent agreement with an idealized grey radiative-convective model with no shortwave absorption for D = 1 and C ...
متن کاملConvective Generation of Equatorial Superrotation in Planetary Atmospheres
In rapidly rotating planetary atmospheres that are heated from below, equatorial superrotation can occur through convective generation of equatorial Rossby waves. If the heating from below is sufficiently strong that convection penetrates into the upper troposphere, then the convection generates equatorial Rossby waves, which can induce the equatorward angular momentum transport necessary for s...
متن کاملOn the radiative equilibrium of irradiated planetary atmospheres
Context. The evolution of stars and planets is mostly controlled by the properties of their atmosphere. This is particularly true in the case of exoplanets close to their stars, for which one has to account both for an (often intense) irradiation flux, and from an intrinsic flux responsible for the progressive loss of the inner planetary heat. Aims. The goals of the present work are to help und...
متن کاملAn automated method for tracking clouds in planetary atmospheres
We present an automated method for cloud tracking which can be applied to planetary images. The method is based on a digital correlator which compares two or more consecutive images and identifies patterns by maximizing correlations between image blocks. This approach bypasses the problem of feature detection. Four variations of the algorithm are tested on real cloud images of Jupiter’s white o...
متن کاملRadiative Constraints on the Hydrological Cycle in an Idealized Radiative–Convective Equilibrium Model
The radiative constraints on the partitioning of the surface energy budget and, hence, on the strength of the hydrological cycle are analyzed in an idealized one-dimensional radiative–convective equilibrium model formulated in terms of the energy budgets at the top of the atmosphere, the subcloud layer, and the free atmosphere, which enables it to predict both surface relative humidity and the ...
