Detecting changes in large-scale metrics of climate in short integrations of a global storm-resolving model of the atmosphere

Environmental Research: Climate
Recent advances have allowed for integration of global storm resolving models (GSRMs) to a timescale of several years. These short simulations are sufficient for studying aggregated statistics of short-timescale and small spatial-scale phenomena; however,

Vertical motions in clouds from EarthCare satellite and a global storm-resolving modeling. [PDF]

Sci Rep
Understanding vertical motions in clouds is essential for improving weather and climate models but remains challenging due to limited observations. The newly launched EarthCARE satellite with a Doppler radar now provides global measurements of how fast ...

Tropical Cirrus in Global‐Storm Resolving Models: 3. Seasonal Changes and TTL Cirrus in the Tropical Western Pacific Using DYAMOND

Earth and Space Science
Recent advances in computer modeling have spurred the production of several global storm‐resolving models (GSRMs), which explicitly represent atmospheric circulations from convective to global scales.

A Single Tropical Rainbelt in Global Storm‐Resolving Models: The Role of Surface Heat Fluxes Over the Warm Pool

Journal of Advances in Modeling Earth Systems
Global uncoupled storm‐resolving simulations using the ICOsahedral Non‐hydrostatic (ICON) model with prescribed sea surface temperature (SST) show a double band of precipitation in the Western Pacific, a feature explained by reduced precipitation over ...

Machine‐Learned Climate Model Corrections From a Global Storm‐Resolving Model: Performance Across the Annual Cycle [PDF]

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 ...

A First Look at the Global Climatology of Low‐Level Clouds in Storm Resolving Models

Journal of Advances in Modeling Earth Systems
The representation of subtropical stratocumulus and trade‐wind cumulus clouds by preliminary versions of Integrated Forecasting System (IFS) and ICON km‐scale global coupled climate models is explored.

Climate sensitivity and relative humidity changes in global storm-resolving model simulations of climate change. [PDF]

Sci Adv
The climate simulation frontier of a global storm-resolving model (GSRM; or k-scale model because of its kilometer-scale horizontal resolution) is deployed for climate change simulations. The climate sensitivity, effective radiative forcing, and relative

Trends in vertical wind velocity variability reveal cloud microphysical feedback [PDF]

Nature Communications
By controlling supersaturation vertical air motion influences how aerosols activate into cloud droplets and ice crystals. This effect is difficult to represent accurately in atmospheric models as they cannot typically resolve the sub-kilometer scale ...
