Early development and tuning of a global coupled cloud resolving model, and its fast response to increasing CO2 [PDF]

, 2022
Since the dawn of functioning numerical dynamical atmosphere- and ocean models, their resolution has steadily increased, fed by an exponential growth in computational capabilities.

Resolving Convection Doubles Sahel's Contribution to Global Dust Emission During the Monsoon Season

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Current climate models struggle to capture the mean state and variability of dust emissions. This is partially due to their inability to resolve convection, a consequence of their relatively coarse spatial resolution. Via analysis of output from an offline dust emission scheme forced with output from a global storm‐resolving model, we show ...

How Convective Mass Flux Responds to Environmental Humidity

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 2, February 2026.
Abstract Our goal in this study is to characterize the relationship between lower tropospheric environmental humidity and convective mass flux in the tropics. To do so, we have created gridded convective mass flux data sets from five global storm‐resolving models (GSRMs). We have three principal findings.

Horizontal Grid Spacing Convergence of Aquaplanet Experiments Using a Global‐Storm Resolving Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 2, February 2026.
Abstract Aquaplanet experiments are used to investigate the statistical convergence of the Global Storm‐Resolving model (GSRM) ICOsahedral Nonhydrostatic (ICON) model, under successive, two‐fold horizontal grid spacing refinements from 160 to 1.25 km. A methodology based on the Richardson extrapolation method is used with the aquaplanet hemispherical ...

Ocean Eddies Lower the Global‐Mean, Maximum Intensity of Tropical Cyclones in a One‐Year Global, Coupled Simulation

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We quantify the impact of ocean eddies on the global‐mean tropical‐cyclone intensity in a 1‐year simulation run with a coupled atmosphere‐ocean model with quite‐realistic seasonal climatology that resolves both Tropical cyclones (TCs) and ocean eddies.

Multiscale Convective Circulations and Scale Interactions in a Global Storm‐Resolving Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 1, January 2026.
Abstract Understanding the relation between large‐scale (≳ $\gtrsim $100 km) tropical atmospheric motions and small‐scale convective circulations remains a challenge, despite such multiscale interactions playing a crucial role in the dynamics of large‐scale circulations.

Data-Driven Equation Discovery of a Cloud Cover Parameterization

, 2023
A promising method for improving the representation of clouds in climate models, and hence climate projections, is to develop machine learning-based parameterizations using output from global storm-resolving models.

Evaluation of E3SM Simulated Aerosols and Aerosol‐Cloud Interactions Across GCM and Convection‐Permitting Scales

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.
Abstract This paper introduces an Earth system modeling testbed for predicting aerosols and aerosol‐cloud interactions (ACIs) at convection‐permitting scales. Using the Energy Exascale Earth System Model (E3SM) version 2 with a four‐mode Modal Aerosol Module, we conduct simulations at 3.25 km resolution on a regionally refined mesh (RRM) across four ...

A causal intercomparison framework unravels precipitation drivers in Global Storm-Resolving Models

npj Climate and Atmospheric Science
Correctly representing convective precipitation remains a long-standing problem in climate models, due to its highly parameterized nature and unclear role of drivers interacting over a wide range of spatial scales.

Characterization of the thermodynamic phase of mid-base and low-base clouds over the Arctic and the Southern Ocean [PDF]

Wolken bedecken einen Großteil der Erde und beeinflussen ihre Strahlungsbilanz. Systematische Fehler in der Repräsentation von Wolken und deren Phase können zu Strahlungsfehlern in Modellen führen, was sich beispielsweise wiederum auf die ...
