Geophysical Research LettersCold pools formed by precipitating convective clouds are an important source of mesoscale temperature variability. However, their sub‐mesoscale (100 m–10 km) structure has not been quantified, impeding validation of numerical models and understanding of ...

External Drivers and Mesoscale Self‐Organization of Shallow Cold Pools in the Trade‐Wind Regime
Journal of Advances in Modeling Earth SystemsRecent observations of the trade‐wind regions highlight the covariability between cold‐pool properties and mesoscale cloud organization. Given the covariability of organization with cloud cover and albedo, this suggests a potential impact of cold pools ...

Tracking the Gust Fronts of Convective Cold Pools [PDF]
Journal of Geophysical Research D: Atmospheres, 2019 AbstractIt is increasingly acknowledged that cold pools can influence the initiation of new convective cells. Yet the full complexity of convective organization through cold pool interaction is poorly understood. This lack of understanding may partially be due to the intricacy of the dynamical pattern formed by precipitation cells and their cold pools.

On the sizes and lifetimes of cold pools [PDF]
Quarterly Journal of the Royal Meteorological Society, 2016 Cold pools of air, which are formed by evaporating precipitation, play a critical role in the triggering of new precipitation. Despite their recognized importance, little effort has been devoted to building simple models of their dynamics. Here, analytical equations are derived for the radius, height, and buoyancy of a cylindrical cold pool as a ...

Absence of West Nile and Usutu Virus Persistence in Overwintering Mosquitoes in Northeastern France: Insights from Cold-Season Surveillance [PDF]
VirusesEmerging arboviruses of the Orthoflavivirus genus such as West Nile virus (WNV) and Usutu virus (USUV), primarily transmitted by Culex mosquitoes, pose significant public health threats due to their ability to cause severe neurological diseases in humans

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.

Geophysical 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.

Journal of Geophysical Research: Atmospheres, 2016 AbstractThe mechanisms by which sensible heat fluxes (SHFs) alter cold pool characteristics and dissipation rates are investigated in this study using idealized two‐dimensional numerical simulations and an environment representative of daytime, dry, continental conditions.

Sensitivity of Summertime Convection to Aerosol Loading and Properties in the United Arab Emirates
Atmosphere, 2021 The Weather Research and Forecasting (WRF) model is used to investigate convection–aerosol interactions in the United Arab Emirates (UAE) for a summertime convective event. Both an idealized and climatological aerosol distributions are considered.

The Diurnal Path to Persistent Convective Self‐Aggregation
Journal of Advances in Modeling Earth Systems, 2022 Clustering of tropical thunderstorms constitutes an important climate feedback because it influences the radiative balance. Convective self‐aggregation (CSA) is a profound modeling paradigm for explaining the clustering of tropical oceanic thunderstorms.
