Muted Amazon Rainfall Response to Deforestation in a Global Storm‐Resolving Model
Geophysical Research LettersOngoing Amazon deforestation has raised concerns about forest dieback via induced precipitation changes. Previous studies have found that complete deforestation reduces evapotranspiration, contributing to low precipitation rates that would limit the ...

The Fractal Nature of Clouds in Global Storm‐Resolving Models [PDF]
Geophysical Research Letters, 2021 AbstractClouds in observations are fractals: they show self‐similarity across scales ranging from 1 to 1,000 km. This includes individual storms and large‐scale cloud structures typical of organized convection. It is not known whether global storm‐resolving models reproduce the observed fractal scaling laws for clouds and organized convection.

Tropical Cyclones in Global Storm-Resolving Models [PDF]
Journal of the Meteorological Society of Japan, 2021 Recent progress in computing and model development has initiated the era of global storm-resolving modeling and with it the potential to transform weather and climate prediction. Within the general theme of vetting this new class of models, the present study evaluates nine global-storm resolving models in their ability to simulate tropical cyclones ...

Impact of Microphysics on Tropical Precipitation Extremes in a Global Storm‐Resolving Model [PDF]
Geophysical Research Letters, 2021 Abstract The impact of microphysics on tropical precipitation extremes is explored with a global storm‐resolving model by modifying the terminal velocity of raindrops. Depending on the time scales, precipitation extremes respond differently.

The Added Value of Large-eddy and Storm-resolving Models for Simulating Clouds and Precipitation [PDF]
Journal of the Meteorological Society of Japan, 2020 More than one hundred days were simulated over very large domains with fine (0.156 km to 2.5 km) grid spacing for realistic conditions to test the hypothesis that storm (kilometer) and large-eddy (hectometer) resolving simulations would provide an improved representation of clouds and precipitation in atmospheric simulations.

Tropical Cirrus in Global Storm‐Resolving Models: 1. Role of Deep Convection [PDF]
Earth and Space Science, 2022 Pervasive cirrus clouds in the upper troposphere and tropical tropopause layer (TTL) influence the climate by altering the top‐of‐atmosphere radiation balance and stratospheric water vapor budget.

Journal of Advances in Modeling Earth Systems, 2023 One approach to improving the accuracy of a coarse‐grid global climate model is to add machine‐learned (ML) state‐dependent corrections to the prognosed model tendencies, such that the climate model evolves more like a reference fine‐grid global storm ...

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

On the Realism of Tropical Cyclone Intensification in Global Storm‐Resolving Climate Models
Geophysical Research LettersThe physical processes governing a tropical cyclone's lifecycle are largely understood, but key processes occur at scales below those resolved by global climate models. Increased resolution may help simulate realistic tropical cyclone intensification. We

Geophysical Research Letters, 2022 AbstractDaily and sub‐daily precipitation statistics are investigated from three global model ensembles: (a) global storm‐resolving models (GSRMs) with typical horizontal resolutions of ∼4 km, (b) “high”‐resolution global models with typical resolutions of ∼50 km and (c) “standard”‐resolution global models with typical resolutions of ∼100 km.
