Multiscale Convective Circulations and Scale Interactions in a Global Storm‐Resolving Model
Journal of Advances in Modeling Earth SystemsUnderstanding the relation between large‐scale (≳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. In

Weaker land-atmosphere coupling in global storm-resolving simulation. [PDF]
Proc Natl Acad Sci U S ASignificance The soil moisture–precipitation feedback plays an important role in shaping climate patterns over land. However, the sign of this feedback remains a topic of ongoing debate.

Investigating the sign of stratocumulus adjustments to aerosols in the ICON global storm-resolving model [PDF]
Atmospheric Chemistry and PhysicsAerosols can cause brightening of stratocumulus clouds, thereby cooling the climate. Observations and models disagree on the magnitude of this cooling, partly because of the aerosol-induced liquid water path (LWP) adjustment, with climate models ...

Reduced cloud cover errors in a hybrid AI-climate model through equation discovery and automatic tuning [PDF]
Scientific ReportsCloud-related parameterizations remain a leading source of uncertainty in climate projections. Although machine learning holds promise for Earth system models (ESMs), many data-driven parameterizations lack interpretability, physical consistency, and ...

Advancing precipitation prediction using a new-generation storm-resolving model framework – SIMA-MPAS (V1.0): a case study over the western United States [PDF]
Geoscientific Model Development, 2022 Global climate models (GCMs) have advanced in many ways as computing power has allowed more complexity and finer resolutions. As GCMs reach storm-resolving scales, they need to be able to produce realistic precipitation intensity, duration, and frequency
