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; ork-scale model because of its kilometer-scale horizontal resolution) is deployed for climate change simulations. The climate sensitivity, effective radiative forcing, and relative humidity changes are assessed in multiyear atmospheric GSRM simulations with perturbed sea-surface ...

On the robustness of aerosol effects on an idealized supercell storm simulated with a cloud system-resolving model [PDF]

Atmospheric Chemistry and Physics, 2012
A cloud system-resolving model (the Weather Research and Forecasting model) with 1 km horizontal grid spacing is used to investigate the response of an idealized supercell storm to increased cloud droplet concentrations associated with polluted ...

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

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 ...

Tropical Cirrus Are Highly Sensitive to Ice Microphysics Within a Nudged Global Storm‐Resolving Model

Geophysical Research Letters
Cirrus dominate the longwave radiative budget of the tropics. For the first time, the variability in cirrus properties and longwave cloud radiative effects (CREs) that arises from using different microphysical schemes within nudged global storm‐resolving

The North Sea Andrea storm and numerical simulations [PDF]

Natural Hazards and Earth System Sciences, 2014
A coupling of a spectral wave model with a nonlinear phase-resolving model is used to reconstruct the evolution of wave statistics during a storm crossing the North Sea on 8–9 November 2007.

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.

Muted Amazon Rainfall Response to Deforestation in a Global Storm‐Resolving Model

Geophysical Research Letters
Ongoing 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 ...

On the Realism of Tropical Cyclone Intensification in Global Storm‐Resolving Climate Models

Geophysical Research Letters
The 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

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

Journal of Advances in Modeling Earth Systems
Understanding 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

Analysis of the environments of seven Mediterranean tropical-like storms using an axisymmetric, nonhydrostatic, cloud resolving model [PDF]

Natural Hazards and Earth System Sciences, 2007
Tropical-like storms on the Mediterranean Sea are occasionally observed on satellite images, often with a clear eye surrounded by an axysimmetric cloud structure. These storms sometimes attain hurricane intensity and can severely affect coastal lands.
