Clouds and Radiation in a Mock‐Walker Circulation

Journal of Advances in Modeling Earth Systems, 2021
The Walker circulation connects the regions with deep atmospheric convection in the western tropical Pacific to the shallow‐convection, tropospheric subsidence, and stratocumulus cloud decks of the eastern Pacific.

Coupled radiative convective equilibrium simulations with explicit and parameterized convection

Journal of Advances in Modeling Earth Systems, 2016
Radiative convective equilibrium has been applied in past studies to various models given its simplicity and analogy to the tropical climate. At convection-permitting resolution, the focus has been on the organization of convection that appears when using fixed sea surface temperature (SST).

Thermal Equilibrium Curves and Turbulent Mixing in Keplerian Accretion Disks [PDF]

, 1999
We consider vertical heat transport in Keplerian accretion disks, including the effects of radiation, convection, and turbulent mixing driven by the Balbus-Hawley instability, in astronomical systems ranging from dwarf novae (DNe), and soft X-ray ...

Sensitivity of the Horizontal Scale of Convective Self‐Aggregation to Sea Surface Temperature in Radiative Convective Equilibrium Experiments Using a Global Nonhydrostatic Model

Journal of Advances in Modeling Earth Systems, 2022
We conduct radiative convection equilibrium experiments using a global nonhydrostatic model to investigate the dependence of convective self‐aggregation (CSA) on domain size and sea surface temperature (SST).

Numerical simulations of surface convection in a late M-dwarf [PDF]

, 2002
Based on detailed 2D and 3D numerical radiation-hydrodynamics (RHD) simulations of time-dependent compressible convection, we have studied the dynamics and thermal structure of the convective surface layers of a prototypical late-type M-dwarf (Teff~2800K

On baroclinic adjustment of a radiative convective atmosphere

Annals of Geophysics, 1998
In this paper we study the implication of the hypothesis that the radiative convective equilibrium climate is neutral with respect to baroclinic eddies. If such neutral state is achieved by tropopause height readjustment, we find that the sensitivity of ...

Structure and Evolution of Low-Mass Stars: An Overview and Some Open Problems [PDF]

, 2007
A review is presented of some of the ingredients, assumptions and techniques that are used in the computation of the structure and evolution of low-mass stars. Emphasis is placed on several ingredients which are still subject to considerable uncertainty.

Convective Dynamics and the Response of Precipitation Extremes to Warming in Radiative–Convective Equilibrium [PDF]

Journal of the Atmospheric Sciences, 2020
AbstractTropical precipitation extremes are expected to strengthen with warming, but quantitative estimates remain uncertain because of a poor understanding of changes in convective dynamics. This uncertainty is addressed here by analyzing idealized convection-permitting simulations of radiative–convective equilibrium in long-channel geometry. Across a

The impact of a land-sea contrast on convective aggregation in radiative-convective equilibrium

Journal of Advances in Modeling Earth Systems, 2022
AbstractConvective aggregation is an important atmospheric phenomenon which frequently occurs in idealized models in radiative‐convective equilibrium (RCE), where the effects of land, rotation, sea surface temperature gradients, and the diurnal cycle are often removed.

The Inhomogeneity Effect. III. Weather Impacts on the Heat Flow of Hot Jupiters

The Astrophysical Journal, 2023
The interior flux of a giant planet impacts atmospheric motion, and the atmosphere dictates the interior’s cooling. Here we use a non-hydrostatic general circulation model (Simulating Non-hydrostatic Atmospheres on Planets) coupled with a multi-stream ...
