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.

A Physically Based Definition of Convectively Generated Density Currents: Detection and Characterization in Convection‐Permitting Simulations

Journal of Advances in Modeling Earth Systems, 2021
In this study, a conceptual model to define convective density currents is proposed. Based on theory, observations and modeling studies, we define convective density currents as 3D coherent structures with an anomalously cold core, an adjacent wind gust,

The Cloud-resolving model Radar SIMulator (CR-SIM) Version 3.3: description and applications of a virtual observatory [PDF]

Geoscientific Model Development, 2020
Ground-based observatories use multisensor observations to characterize cloud and precipitation properties. One of the challenges is how to design strategies to best use these observations to understand these properties and evaluate weather and climate ...

Intensification of Precipitation Extremes with Warming in a Cloud-Resolving Model [PDF]

Journal of Climate, 2011
Abstract 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. While this idealized setting does not allow for several factors that influence precipitation in the tropics, it does allow for an ...

A deep learning framework for analyzing cloud characteristics of aggregated convection using cloud‐resolving model simulations

Atmospheric Science Letters, 2023
This study introduces a framework to extract the high‐dimensional nonlinear relationships among state variables for aggregated convection. The prototype of such a framework is developed that applies the convolutional neural network models (CNN models) to

Cloud-resolving model for weather modification in China [PDF]

Chinese Science Bulletin, 2012
Weather modification is widely carried out in China. It is important to develop an operational model for weather modification to predict the microphysical features of cloud and precipitation and to help locate possible seeding areas. A two-moment microphysics scheme is developed using a quasi-implicit calculation method.

A short review of numerical cloud-resolving models [PDF]

Tellus A: Dynamic Meteorology and Oceanography, 2017
A cloud-resolving model (CRM) allows performing numerical simulations of convective clouds, such as shallow cumulus and stratocumulus, or storms and squall-lines with a resolution on the order of a few tens of metres to a few kilometres over a limited-area 4D (time and space) domain.

Modeling Land‐Atmosphere Coupling at Cloud‐Resolving Scale Within the Multiple Atmosphere Multiple Land (MAML) Framework in SP‐E3SM

Journal of Advances in Modeling Earth Systems, 2023
Representing subgrid variabilities of land surface processes and their upscaled effects is crucial for global climate modeling. Here, we implement a multiple atmosphere multiple land (MAML) framework in the superparamaterized version of E3SM (SP‐E3SM) to
