Evaluation of Global Storm‐Resolving Models in DYAMOND‐Winter: Radiation, Precipitation, Water Vapor, and Convective Organization

Journal of Advances in Modeling Earth Systems
We present a comprehensive evaluation of 13 global storm‐resolving models participating in the DYnamics of the Atmospheric general circulation Modeled On Non‐hydrostatic Domains (DYAMOND) Winter intercomparison project, focusing on their ability to ...

Bridging the Gap Between Global Weather Prediction and Global Storm‐Resolving Simulation: Introducing the GFDL 6.5‐km SHiELD

Journal of Advances in Modeling Earth Systems
We introduce a 6.5‐km version of the Geophysical Fluid Dynamics Laboratory (GFDL)'s System for High‐resolution prediction on Earth‐to‐Local Domains (SHiELD).

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,

Process‐Oriented Calibration of a Turbulence Scheme in the DOE's Global Storm‐Resolving Model Using Machine Learning

Geophysical Research Letters
A process‐oriented calibration framework is developed for the Simplified Higher‐Order Closure (SHOC) turbulence scheme in DOE's Simple Cloud Resolving E3SM Atmospheric Model (SCREAM). This framework leverages machine learning surrogates and observational

Impact of Warmer Sea Surface Temperature on the Global Pattern of Intense Convection: Insights From a Global Storm Resolving Model

Geophysical Research Letters, 2022
Intense convection (updrafts exceeding 10 m s−1) plays an essential role in severe weather and Earth's energy balance. Despite its importance, how the global pattern of intense convection changes in response to warmed climates remains unclear, as ...

A Global Survey of Rotating Convective Updrafts in the GFDL X‐SHiELD 2021 Global Storm Resolving Model

Journal of Geophysical Research: Atmospheres, 2023
We present the global characteristics of rotating convective updrafts in the 2021 version of GFDL's eXperimental System for High‐resolution prediction on Earth‐to‐Local Domains (X‐SHiELD), a kilometer‐scale global storm resolving model (GSRM).

The Contribution of Convection to the Stratospheric Water Vapor: The First Budget Using a Global Storm‐Resolving Model

Journal of Geophysical Research: Atmospheres, 2022
The deepest convection on Earth injects water in the tropical stratosphere, but its contribution to the global stratospheric water budget remains uncertain.

Impact of Microphysics on Tropical Precipitation Extremes in a Global Storm‐Resolving Model

Geophysical Research Letters, 2021
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.

Predicting Compound Coastal Flooding in Embayment-Backed Urban Catchments: Seawall and Storm Drain Implications

Journal of Marine Science and Engineering, 2023
Urban coastal flooding is a global humanitarian and socioeconomic hazard. Rising sea levels will increase the likelihood of hydrologic events interacting with high marine water levels.

Toward Eliminating the Decades‐Old “Too Zonal and Too Equatorward” Storm‐Track Bias in Climate Models

Journal of Advances in Modeling Earth Systems, 2023
Generations of climate models exhibit biases in their representation of North Atlantic storm tracks, which tend to be too far near the equator and too zonal. Additionally, models have difficulties simulating explosive cyclone growth. These biases are one
