A Robust Constraint on the Response of Convective Mass Fluxes to Warming
Journal of Advances in Modeling Earth Systems, Volume 17, Issue 4, April 2025.Abstract A fundamental quantity in tropical dynamics is the “convective mass flux,” which measures the rate at which mass is transported upwards per unit area in convective updrafts. Convective mass flux encodes information about the frequency and intensity of thunderstorms, and has been linked to the strength of the large‐scale tropical circulation ...

On the Dependence of Simulated Convection on Domain Size in CRMs
Journal of Advances in Modeling Earth Systems, Volume 17, Issue 3, March 2025.Abstract We present a heuristic model to explain the suppression of deep convection in convection‐resolving models (CRMs) with a small number of grid columns, such as those used in super‐parameterized or multi‐scale modeling framework (MMF) general circulation models (GCM) of the atmosphere.

Sensitivity of Self‐Aggregation and the Key Role of the Free Convection Distance
Journal of Advances in Modeling Earth Systems, Volume 17, Issue 3, March 2025.Abstract Recently, Biagioli and Tompkins (2023, https://doi.org/10.1029/2022ms003231) used a simple stochastic model to derive a dimensionless parameter to predict convective self aggregation (SA) development, which was based on the derivation of the maximum free convective distance dclr $\left({d}_{\mathit{clr}}\right)$ expected in the pre‐aggregated,

Basic Physics Predicts Stronger High Cloud Radiative Heating With Warming
Geophysical Research Letters, Volume 51, Issue 24, 28 December 2024.Abstract Radiative heating of clouds, particularly those in the upper troposphere, alters temperature gradients in the atmosphere, affecting circulation and precipitation in today's and future climates. However, the response of cloud radiative heating to global warming remains largely unknown.

Journal of Advances in Modeling Earth Systems, Volume 16, Issue 10, October 2024.Abstract In simulations of radiative‐convective equilibrium (RCE), and with sufficiently large domains, organized convection enhances top of atmosphere outgoing longwave radiation due to the reduced cloud coverage and drying of the mean climate state. As a consequence, estimates of climate sensitivity and cloud feedbacks may be affected. Here, we use a

Geophysical Research Letters, Volume 51, Issue 15, 16 August 2024.Abstract We simulate the Madden‐Julian oscillation (MJO) over an aquaplanet with uniform surface temperature using the multiscale modeling framework (MMF) configuration of the Energy Exascale Earth System Model (E3SM‐MMF). The model produces MJO‐like features that have a similar spatial structure and propagation behavior to the observed MJO. To explore

The Transition to Double‐Celled Circulations in Mock‐Walker Simulations
Geophysical Research Letters, Volume 51, Issue 14, 28 July 2024.Abstract Mock‐Walker simulations have the potential to play a key role in a tropical model hierarchy, bridging small‐scale Radiative‐Convective Equilibrium simulations and global models of tropical circulations. We demonstrate that mock‐Walker simulations transition from single‐ to double‐celled overturning circulations as mean Sea Surface Temperature (

The Potential of Absorbing Aerosols to Enhance Extreme Precipitation
Geophysical Research Letters, Volume 51, Issue 10, 28 May 2024.Abstract 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 extreme events remains unclear.

Journal of Advances in Modeling Earth Systems, Volume 16, Issue 5, May 2024.Abstract Tropical high cloud cover decreases with surface warming in most general circulation models. This reduction, according to the “stability‐iris” hypothesis, is thermodynamically controlled and linked to a decrease in the radiatively‐driven clear‐sky convergence, when the peak anvil clouds rise because of the rising isotherms.
