How Variable are Cold Pools?

open access: yesGeophysical Research Letters, 2023
Cold pools formed by precipitating convective clouds are an important source of mesoscale temperature variability. However, their sub-mesoscale (100 m to 10 km) structure has not been studied, which impedes validation of numerical models and understanding of their atmospheric and societal impacts.

Environmental Modulation of Mechanical and Thermodynamic Forcing from Cold Pool Collisions

open access: yesJournal of the Atmospheric Sciences, 2022
Cold pools can initiate new convection by increasing vertical velocity (mechanical forcing) and locally enhancing moisture content (thermodynamic forcing).

Mesoscale Observational Analysis of Isolated Convection Associated with the Interaction of the Sea Breeze Front and the Gust Front in the Context of the Urban Heat Humid Island Effect

open access: yesAtmosphere, 2022
An isolated convection was unexpectedly initiated in the evening of 1 August 2019 around the Tianjin urban region (TUR), which happened at some distance from the shear line at lower level and the preexisting convection to the South, analyzed by using ...

Development and maintenance of squall line in a weak vertical wind shear environment

open access: yes暴雨灾害, 2021
Based on conventional observation data, automatic weather station data and CINRAD-SA Doppler radar data, we analyzed the weather background, environmental conditions, development mechanism and the gale that caused for the squall line event on 27 May 2018

Satellite‐Derived Characteristics of Saharan Cold Pool Outflows During Boreal Summer

open access: yesJournal of Geophysical Research - Atmospheres, 2021
Cold pool outflows (CPOs) are thought to be the most significant meteorological mechanism of mineral dust emission from the world's largest source in the central and western Sahara in boreal summer. An absence of CPOs from numerical models and reanalyses

Synoptic Analysis of Upper- Cold Air Pool Effects on Generating or Intensifying Rainfall in the Warm Season in East Azerbaijan [PDF]

open access: yesجغرافیا و توسعه, 2016
In synoptic meteorology, establishment of cold air masses  at the middle and upper levels of the atmosphere is called cold air cell or cold air pool (Cold Pool).

A cold pool perturbation scheme to improve convective initiation in convection‐permitting models

open access: yesQuarterly Journal of the Royal Meteorological Society, 2021
Cold pools originate from evaporation in precipitating downdraughts and spread as density currents at the surface. Vertical motion at the leading edge of the cold pool is an important trigger for new convective cells in organised convective storms ...

Cold Pool Characteristics of Tornadic Quasi-Linear Convective Systems and Other Convective Modes Observed during VORTEX-SE

open access: yesMonthly Weather Review, 2021
Many numerical studies have focused on the importance of baroclinically generated vorticity at the edge of cold pools in supercellular tornadogenesis, and observational work has consistently found that strongly tornadic supercells have less dense, more ...
