Convective Self‐Aggregation in Diurnally Oscillating Sea Surface Temperature and Solar Forcing Experiments

Journal of Advances in Modeling Earth Systems
We have addressed convective self‐aggregation (CSA) in steady and oscillating sea surface temperature (SST) and solar radiation (SOLIN) cloud‐resolving model simulations in a non‐rotating radiative‐convective equilibrium (RCE) framework.

Clouds, Circulation, and Climate Sensitivity in a Radiative‐Convective Equilibrium Channel Model

Journal of Advances in Modeling Earth Systems, 2017
Tropical cloud and circulation changes are large sources of uncertainty in future climate change. This problem owes partly to the scale separation between large‐scale tropical dynamics ( ∼104 km) and convective dynamics ( ∼1 km), which generally requires

First Calculations of Starspot Spectra Based on 3D Radiative Magnetohydrodynamics Simulations

The Astrophysical Journal Letters
Accurate calculations of starspot spectra are essential for multiple applications in astronomy. The current standard is to represent starspot spectra by spectra of stars that are cooler than the quiet star regions.

Moisture‐radiative cooling instability

Journal of Advances in Modeling Earth Systems, 2016
Radiative‐convective equilibrium (RCE)—the statistical equilibrium state of the atmosphere where convection and radiation interact in the absence of lateral transport—is widely used as a basic‐state model of the tropical atmosphere.

The Potential of Absorbing Aerosols to Enhance Extreme Precipitation

Geophysical Research Letters
Understanding the impact of various climate forcing agents, such as aerosols, on extreme precipitation is socially and scientifically vital. While anthropogenic absorbing aerosols influence Earth's energy balance and atmospheric convection, their role in

The Unreasonable Efficiency of Total Rain Evaporation Removal in Triggering Convective Self‐Aggregation

Geophysical Research Letters
The elimination of rain evaporation in the planetary boundary layer (PBL) has been found to lead to convective self‐aggregation (CSA) even without radiative feedback, but the precise mechanisms underlying this phenomenon remain unclear.

A Thermodynamic Closure Model for Titan’s Surface Temperature: Its Long-Term Stability Anchored to Methane’s Triple Point

Geosciences
We develop a minimal thermodynamic model to predict Titan’s surface temperature based on radiative–convective equilibrium and the principle of maximum entropy production (MEP).

A Refined Zero‐Buoyancy Plume Model for Large‐Scale Atmospheric Profiles and Anvil Clouds in Radiative‐Convective Equilibrium

Journal of Advances in Modeling Earth Systems
A simple analytical model, the zero‐buoyancy plume (ZBP) model, has been proposed to understand how small‐scale processes such as plume‐environment mixing and evaporation affect the steady‐state structure of the atmosphere.

Implementation and Exploration of Parameterizations of Large‐Scale Dynamics in NCAR's Single Column Atmosphere Model SCAM6

Journal of Advances in Modeling Earth Systems
A single column model with parameterized large‐scale (LS) dynamics is used to better understand the response of steady‐state tropical precipitation to relative sea surface temperature under various representations of radiation, convection, and ...
