Abstract This study investigates how climatological temperature fields in simulations are influenced by the choice of moist thermodynamic formulations. Two formulations were compared: one developed to ensure internal thermodynamic consistency, and a simpler approximation similar to those commonly used in meteorological and climate models.

Responses to Humidity and Temperature Perturbations in High‐Resolution Simulations of Convection
Abstract Convection parameterization is a leading source of uncertainty in global and regional climate models, and a lack of ground truth complicates the assessment of convection scheme performance. Here we test a linear framework for quantifying convective responses, using two models run at convection‐permitting resolution, to examine model responses ...

No “Wet Gets Wetter” in Kilometer‐Scale Mock‐Walker Circulations
Abstract Many climate model simulations and limited observations indicate that regions of tropical ascent and precipitation contract in response to surface warming. This response has well‐studied implications for the width of the zonal‐ and annual‐mean Intertropical Convergence Zone, but its applicability to zonally asymmetric circulations such as the ...

Abstract Hot and moist “hothouse” climates occurred in Earth's past and are expected in Earth's far future climate, driven by increasing solar luminosity. In hothouse climate regimes, precipitation transitions from a quasi‐steady state, as in present‐day tropical convection, to an “episodic deluge” or relaxation‐oscillator (RO) regime where ...

Abstract 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. Our experiment designs are motivated by land‐ocean heterogeneity of atmospheric convection.

Abstract The development of the Simplified Cloud Resolving Energy Exascale Earth System Atmosphere Model (SCREAMv1) enables global storm‐resolving simulations on modern GPU‐based supercomputers. However, the high computational cost of SCREAMv1 limits its routine use for process‐level studies, creating a need for efficient proxy configurations.

Why Idealized Models Are More Important Than Ever in Earth System Science
Abstract Simulating the Earth system is crucial for studying Earth's climate and how it changes. Modeling approaches that simplify the Earth system while retaining key characteristics are important tools to advance understanding. The simplicity and flexibility of idealized models enables imaginative science and makes them powerful educational tools ...

Moisture-space composites for each simulation in the 2-d RCE ensemble presented in Sokol & Hartmann (2022).This study examines how the congestus mode of tropical convection is expressed in numerical simulations of radiative-convective equilibrium (RCE ...

Estimates of the Global Clear‐Sky Longwave Radiative Feedback Strength From Reanalysis Data
Abstract We use atmospheric profiles from ERA5, JRA55, and MERRA2 between 1993 and 2023 to estimate Earth's global clear‐sky longwave feedback strength on the seasonal and interannual timescale. Differences in the relationship of relative humidity with skin temperature prior to 2008 lead to interannual feedback strengths between 1.34 Wm−2 K−1 (JRA55 ...

The Impact of Rotation on Tropical Climate, the Hydrologic Cycle, and Climate Sensitivity
This work explores the impact of rotation on tropical convection and climate. As our starting point, we use the RCEMIP experiments as control simulations and run additional simulations with rotation.
