Impacts of initial conditions on cloud-resolving model simulations

Advances in Atmospheric Sciences, 2008
Impacts of initial conditions on cloud-resolving model simulations are investigated using a series of sensitivity experiments. Five experiments with perturbed initial temperature, moisture, and cloud conditions are conducted and compared to the control experiment.

Predictability Mysteries in Cloud-Resolving Models

Monthly Weather Review, 2006
Abstract The rapid amplification of small-amplitude perturbations by the chaotic nature of the atmospheric dynamics intrinsically limits the skill of deterministic weather forecasts. In this study, limited-area cloud-resolving numerical weather prediction (NWP) experiments are conducted to investigate the role of mesoscale processes in ...

Cloud-Resolving Modeling of Precipitation

2011
Precipitation has important impacts on people’s daily life and torrential ­precipitation could bring tremendous losses in economy and cause fatalities. Thus, precipitation always is one of the top priorities in operational forecast and scientific research. Precipitation is a result of convective development under a favorable environment.

Circulations driven by organization gradients in a cloud-resolving model

2022
<p>Multicellular conglomerations of deep convection are commonly observed, but what is the larger-scale importance of this nonrandom spatial structure? We hypothesize (based on the common meaning of the word “organization”) that more-agglomerated convection will out-compete spotty convection for scarce ...

Future Perspective of Cloud-Resolving Modeling

2016
In this chapter, a set of cloud microphysical schemes are simplified based on the grid-scale data from the simulation of tropical rainfall event during TOGA COARE. The basic concept of cloud-resolving convection parameterization and its application to general circulation model simulations are discussed.

Parallel Implementation and Scalability of Cloud Resolving EULAG Model

2012
Progress in the development of the PetaScale implementation of the anelastic EULAG model combined with the warm-rain bulk and bin microphysics schemes, as well its application to multiscale cloud modeling, are presented. A new three-dimensional (3D) model domain decomposition is implemented to increase model performance and scalability.

Investigating tropical squall lines with a cloud resolving model

2021
<p>Investigating tropical squall lines with a cloud resolving model</p><p>Using a cloud resolving model, we attempt to clarify the physical processes responsible for the organization of deep clouds into squall lines in the tropics.

Cloud-Resolving Model Simulations and a Simple Model of an Idealized Walker Cell

Journal of Climate, 2012
Abstract An idealized Walker cell with prescribed sea surface temperature (SST) and prescribed radiative cooling is studied using both a two-dimensional cloud-resolving model (CRM) and a simple conceptual model. In the CRM, for the same SST distribution, the width of the warm pool (area of strong precipitation) varies systematically with

Sensitivity studies of developing convection in a cloud‐resolving model

Quarterly Journal of the Royal Meteorological Society, 2006
AbstractCloud‐resolving models (CRMs) remain an important tool for providing detailed process information about convection. In this short paper I focus on the development of deep convection and consider what can be considered a minimum expense benchmark simulation for comparison with a numerical weather‐prediction model.
