Observational Study of the Thermodynamics and Morphological Characteristics of a Midlatitude Continental Cold Pool Event

Monthly Weather Review, 2020
Convectively generated cold pools are important to the Earth system as they exert strong controls on deep convective-storm initiation, intensity, and life cycle.

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

Atmosphere, 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 ...

Evaluation of a cloudy cold-air pool in the Columbia River basin in different versions of the High-Resolution Rapid Refresh (HRRR) model [PDF]

Geoscientific Model Development, 2023
The accurate forecast of persistent orographic cold-air pools in numerical weather prediction models is essential for the optimal integration of wind energy into the electrical grid during these events.

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

Atmospheric 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.

The Relative Importance of Updraft and Cold Pool Characteristics in Supercell Tornadogenesis Using Highly Idealized Simulations

Journal of the Atmospheric Sciences, 2020
In the recent literature, the conception has emerged that supercell tornado potential may mostly depend on the strength of the low-level updraft, with more than sufficient subtornadic vertical vorticity being assumed to be present in the outflow. In this

Aircraft observations of cold pools under marine stratocumulus [PDF]

Atmospheric 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 ...

Analysis of the Triggering and Maintenance Mechanisms of a Record-Breaking Warm-Sector Extreme-Rainfall Process in Front of an Upper-Level Trough in Tianjin, China

Atmosphere, 2023
A short-time rainstorm exceeding the extreme historical rainfall occurred in the Jinnan District of Tianjin, China, on 3 July 2022. Due to the concentrated time period of precipitation, it caused serious water accumulation in the Jinnan District.

How sensitive are Sahelian mesoscale convective systems to cold‐pool suppression?

Quarterly Journal of the Royal Meteorological Society
Understanding the physical processes driving deep convective storms is an essential prerequisite for understanding the wider tropical atmosphere. Cold pools driven by rainfall evaporation are a ubiquitous feature of mesoscale convective systems (MCSs ...

Measuring the impact of oceanographic indices on species distribution shifts: The spatially varying effect of cold‐pool extent in the eastern Bering Sea

Limnology and Oceanography, 2019
Oceanographers have spent decades developing annual indices that summarize physical conditions in marine ecosystems. Examples include the Pacific Decadal Oscillation, summarizing annual variation in the location of warm waters in the North Pacific, and ...

Impact of Different Double-Moment Microphysical Schemes on Simulations of a Bow-Shaped Squall Line in East China

Atmosphere, 2022
Four typical double-moment cloud microphysical schemes (Milbrandt, Morrison, NSSL and WDM6) in WRF (Weather Research and Forecasting) are used to investigate the impact of the different schemes on the simulation of a straight squall line evolving into a ...
