Ensemble of Radiative‐Convective Equilibrium Simulations Near the Aggregated and Scattered Boundary

Geophysical Research Letters, 2021
An ensemble of 10 radiative‐convective equilibrium (RCE) simulations near the sharp transition zone between scattered and aggregated states are examined in a square‐domain cloud‐resolving model.

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.

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.

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 ...

FAT or FiTT: Are Anvil Clouds or the Tropopause Temperature Invariant?

Geophysical Research Letters, 2019
The Fixed Anvil Temperature (FAT) hypothesis proposes that upper tropospheric cloud fraction peaks at a special isotherm that is independent of surface temperature.

Competing effects of surface albedo and orographic elevated heating on regional climate

Geophysical Research Letters, 2017
All else being equal, a given atmospheric pressure level is thought to be warmer over a plateau than over surrounding nonelevated terrain because of orographic “elevated heating.” However, elevated surfaces are also typically brighter due to reduced ...
