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 ...

Response of precipitation extremes to warming: what have we learned from theory and idealized cloud-resolving simulations, and what remains to be learned?

Environmental Research Letters, 2020
This paper reviews recent important advances in our understanding of the response of precipitation extremes to warming from theory and from idealized cloud-resolving simulations.

Fine Vertical Resolution Radiative‐Convective Equilibrium Experiments: Roles of Turbulent Mixing on the High‐Cloud Response to Sea Surface Temperatures

Journal of Advances in Modeling Earth Systems, 2019
In this study, the vertical resolution dependency of the high‐cloud fraction response on the increase in sea surface temperature was investigated via radiative‐convective equilibrium simulations.

Properties, Changes, and Controls of Deep‐Convecting Clouds in Radiative‐Convective Equilibrium

Journal of Advances in Modeling Earth Systems, 2022
Changes in tropical high clouds associated with deep convection with warming are one of the largest sources of uncertainty in climate feedbacks. Here, we leverage an ensemble of models of many types in an idealized configuration to investigate how and ...

Irradiated Atmospheres. III. Radiative-convective-mixing Equilibrium for Nongray Picket-fence Model

The Astrophysical Journal
The nongray picket-fence model predicts more accurately the temperatures in low-density regions compared to semigray models. This study investigates how the vertical-mixing and convection fluxes modify the picket-fence model.

Explicitly Resolved Cloud Feedbacks in the Radiative‐Convective Equilibrium Model Intercomparison Project

Journal of Advances in Modeling Earth Systems, 2023
Radiative‐convective equilibrium (RCE) is particularly well suited for studying tropical deep‐convection, a regime of clouds that contributes some of the highest uncertainties to the estimates of total cloud feedback.

Self‐Aggregation of Convection in Spatially Varying Sea Surface Temperatures

Journal of Advances in Modeling Earth Systems, 2020
The phenomenon of self‐aggregation of convection was first identified in convection‐permitting simulations of radiative convective equilibrium, characterized by homogeneous boundary conditions and in the absence of planetary rotation.

Modulation of the Bifurcation in Radiative‐Convective Equilibrium by Gray‐Zone Cloud and Turbulence Parameterizations

Journal of Advances in Modeling Earth Systems, 2021
This study investigates the mechanisms by which small‐scale turbulence and cloud physics determine the organization of large‐scale convection in radiative‐convective equilibrium (RCE), an idealization of the tropical atmosphere.

Bulk Radiative‐Convective Equilibrium Is Common Over Mid‐Latitude Land

Geophysical Research Letters
Radiative‐convective equilibrium (RCE) is commonly used as an approximation of the time‐ and space‐averaged tropical atmosphere. We examine two reanalyses to assess the extent to which column‐integrated radiative cooling balances convective heating ...
