To Exascale and Beyond—The Simple Cloud‐Resolving E3SM Atmosphere Model (SCREAM), a Performance Portable Global Atmosphere Model for Cloud‐Resolving Scales

Journal of Advances in Modeling Earth Systems
The new generation of heterogeneous CPU/GPU computer systems offer much greater computational performance but are not yet widely used for climate modeling. One reason for this is that traditional climate models were written before GPUs were available and

Global Cloud-Resolving Models [PDF]

Current Climate Change Reports, 2019
Global cloud-resolving models (GCRMs) are a new type of atmospheric model which resolve nonhydrostatic accelerations globally with kilometer-scale resolution. This review explains what distinguishes GCRMs from other types of models, the problems they solve, and the questions their more commonplace use is raising.

Impact of different definitions of clear-sky flux on the determination of longwave cloud radiative forcing: NICAM simulation results [PDF]

Atmospheric Chemistry and Physics, 2010
Using one month of the cloud-resolving Nonhydrostatic Icosahedral Atmospheric Model (NICAM) simulations, we examined the impact of different definitions of clear-sky flux on the determination of longwave cloud radiative forcing (CRF).

Initialization and dynamical stabilization of a cloud-resolving model

Physics Open, 2022
A multiscale cloud-resolving model (CRM) composed of the anelastic grid equations coupled to viscous turbulence subgrid equations for the wind velocity is presented along with an initialization and dynamical stabilization method named Insertion & ...

Intensification of precipitation extremes with warming in a cloud resolving model [PDF]

Journal of Climate, 2010
A cloud-resolving model is used to investigate the effect of warming on high percentiles of precipitation (precipitation extremes) in the idealized setting of radiative-convective equilibrium.

Early Development and Tuning of a Global Coupled Cloud Resolving Model, and its Fast Response to Increasing CO2

Tellus: Series A, Dynamic Meteorology and Oceanography, 2022
Since the dawn of functioning numerical dynamical atmosphere- and ocean models, their resolution has steadily increased, fed by an exponential growth in computational capabilities.

An Expanded Sensitivity Study of Simulated Storm Life Span to Ventilation Parameterization in a Cloud Resolving Model

Atmosphere, 2023
We performed a sensitivity study on the life span of a numerically simulated storm using the parameterization of the ventilation coefficient. This is an expanded sequel to our previous study, where the ventilation effect of precipitation particles (snow,

Convection‐Permitting Simulations With the E3SM Global Atmosphere Model

Journal of Advances in Modeling Earth Systems, 2021
This paper describes the first implementation of the Δx = 3.25 km version of the Energy Exascale Earth System Model (E3SM) global atmosphere model and its behavior in a 40‐day prescribed‐sea‐surface‐temperature simulation (January 20 through February 28,

Fitting Cumulus Cloud Size Distributions From Idealized Cloud Resolving Model Simulations

Journal of Advances in Modeling Earth Systems, 2023
Whereas it is now widely accepted that cumulus cloud sizes are power‐law distributed, characteristic exponents reported in the literature vary greatly, generally taking values between 1 and >3.
