Role of surface heat fluxes underneath cold pools [PDF]
Geophysical Research Letters, 2016 AbstractThe role of surface heat fluxes underneath cold pools is investigated using cloud‐resolving simulations with either interactive or horizontally homogenous surface heat fluxes over an ocean and a simplified land surface. Over the ocean, there are limited changes in the distribution of the cold pool temperature, humidity, and gust front velocity,

Mechanical Forcing of Convection by Cold Pools: Collisions and Energy Scaling [PDF]
Journal of Advances in Modeling Earth Systems, 2020 Forced mechanical lifting through cold pool gust fronts can trigger new convection and, as previous work highlights, is enhanced when cold pools collide. However, as shown by conceptual models, the organization of the convective cloud field emerging from

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 ...

Cold Pools as Conveyor Belts of Moisture [PDF]
Geophysical Research Letters, 2020 Abstract Observations and simulations have found convective cold pools to trigger and organize subsequent updrafts by modifying boundary layer temperature and moisture as well as by lifting air parcels at the outflow boundaries.

On the Sensitivity of Convective Cold Pools to Mesh Resolution
Journal of Advances in Modeling Earth Systems, 2023 It is well recognized that triggering of convective cells through cold pools (CPs) is key to the organization of convection. Yet, numerous studies have found that both the characterization and parameterization of CP effects in numerical models is ...

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 ...

Particle‐Based Tracking of Cold Pool Gust Fronts [PDF]
Journal of Advances in Modeling Earth Systems, 2020 The gust fronts of convective cold pools (CPs) are increasingly recognized as loci of enhanced triggering for subsequent convective cells. It has so far been difficult to track these gust fronts in high‐resolution data, such as large eddy simulations ...

Characterizing convective cold pools [PDF]
Journal of Advances in Modeling Earth Systems, 2017 AbstractCold pools produced by convective storms play an important role in Earth's climate system. However, a common framework does not exist for objectively identifying convective cold pools in observations and models. The present study investigates convective cold pools within a simulation of tropical continental convection that uses a cloud ...

Mechanisms for convection triggering by cold pools [PDF]
Geophysical Research Letters, 2015 AbstractCold pools are fundamental ingredients of deep convection. They contribute to organizing the subcloud layer and are considered key elements in triggering convective cells. It was long known that this could happenmechanically, through lifting by the cold pools' fronts.
