A Double‐Moment SBU‐YLIN Cloud Microphysics Scheme and Its Impact on a Squall Line Simulation

open access: yesJournal of Advances in Modeling Earth Systems, 2021
A double‐moment version of the SBU‐YLIN cloud microphysical scheme in WRF is introduced. It predicts the mass and number mixing ratios of cloud droplet, rain, cloud ice, and precipitating ice.

RANS Simulation of Local Strong Sandstorms Induced by a Cold Pool with Vorticity

open access: yesAtmosphere, 2020
Local strong sandstorms (LSSs) in northwestern China often occur suddenly in tens of minutes during the late afternoon and by dusk. Observations and theoretical studies have shown the trigger role of cold-air pools over desert areas for the occurrence of

Radar Observed Structural Features and Evolution Mechanism of a Squall Line‐Like Rainband in a Linear Mesoscale Convective System

open access: yesEarth and Space Science, 2022
In this study, multi‐source data, especially weather radar data, were used in the analysis of structural features and evolution of a squall line‐like rainband (SLLR) of a linear mesoscale convective system (MCS) in the eastern slope of the Taihang ...

An Analytical Model of Two‐Dimensional Mesoscale Circulation and Associated Properties Across Squall Lines

open access: yesAGU Advances, 2022
Mesoscale convective systems (MCS) contribute about half of the world's precipitation and create flash flooding as well as other extreme weather events. Despite steady progress in research of these systems in the last several decades, better theoretical ...

A climatology of trade-wind cumulus cold pools and their link to mesoscale cloud organization [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
We present a climatology of trade cumulus cold pools and their associated changes in surface weather, vertical velocity and cloudiness based on more than 10 years of in situ and remote sensing data from the Barbados Cloud Observatory.

Impact of Radar and Surface Data Assimilation on the Forecast of a Nocturnal Squall Line in the Yangtze–Huaihe River

open access: yesAtmosphere, 2022
The impact of radar and surface data assimilation on the forecast of a nocturnal squall line initiated above the stable boundary layer in the Yangtze–Huaihe River is investigated by the Weather Research and Forecasting (WRF) model and its three ...

Aircraft observations of cold pools under marine stratocumulus [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
Although typically associated with precipitating cumuli, cold pools also form under shallower stratocumulus. This study presents cold-pool observations as sampled by the NSF/NCAR C-130, which made cloud and boundary-layer measurements over the ...
