Journal of Advances in Modeling Earth Systems, 2021 Mesoscale organization of convection is typically not represented in global circulation models, and hence its influence on the global circulation is not accounted for. The heating component of a parameterization that represents the dynamical and physical

Properties of semi-convection and convective overshooting for massive stars [PDF]
, 2013 Properties of semi-convection and core convective overshooting of stars with 15 $M_{\odot}$ and 30 $M_{\odot}$ are calculated in the present paper. New methods are used to deal with semi-convection. Different entropy gradient is used when adopting the Schwarzschild method and the Ledoux method which are used to confine the convective boundary and to ...

Analysis of instability patterns in non-Boussinesq mixed convection using a direct numerical evaluation of disturbance integrals [PDF]
, 2009 The Fourier integrals representing linearised disturbances arising from an initially localised source are evaluated numerically for natural and mixed convection flows between two differentially heated plates. The corresponding spatio-temporal instability

Solar Surface Convection [PDF]
Living Reviews in Solar Physics, 2009 We review the properties of solar convection that are directly observable at the solar surface, and discuss the relevant underlying physics, concentrating mostly on a range of depths from the temperature minimum down to about 20 Mm below the visible solar surface.

Rotation of the solar convection zone from helioseismology [PDF]
, 2006 Helioseismology has provided very detailed inferences about rotation of the solar interior. Within the convection zone the rotation rate roughly shares the latitudinal variation seen in the surface differential rotation.

Radiative Heat Transfer Flow of Micropolar Fluid with Variable Heat Flux in a Porous Medium
Nonlinear Analysis, 2008 A two-dimensional steady convective flow of a micropolar fluid past a vertical porous flat plate in the presence of radiation with variable heat flux has been analyzed numerically.
