Cold pool propagation and cold pool-land surface interactions

Convective cold pools are important components of the Earth system as they influence processes such as deep convective initiation, storm longevity and intensity, surface energy fluxes, and aerosol transport. The overarching goal of the research outlined in this dissertation is to investigate the propagation characteristics of cold pools, as well as the

Strong and weak cold pool collisions

, 2022
Collisions between convective cold pools commonly initiate new convective storms. This occurs through enhancements to the vertical velocity through mechanical forcing, and increased water vapor content via thermodynamic forcing. The goal of this study is to investigate the impact of the following four parameters on the mechanical and thermodynamic ...

Identification and Characterization of Persistent Cold Pool Events from Temperature and Wind Profilers in the Columbia River Basin

Journal of Applied Meteorology and Climatology, 2019
Cold pool events occur when deep layers of stable, cold air remain trapped in a valley or basin for multiple days, without mixing out from daytime heating. With large impacts on air quality, freezing events, and especially on wind energy production, they

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,

Analysis of heavy precipitation supercell environment condition and structure in Tianjin coastal area

暴雨灾害, 2019
In the afternoon of 24 July 2016,a local short-term heavy rainfall occurred in Dagang of Tianjin. The maximum rainfall intensity was 95 mm·h-1,which broke the extreme record in the past ten years. The formation environment and structure of the supercell

Convective self‐aggregation, cold pools, and domain size [PDF]

Geophysical Research Letters, 2013
Convective self‐aggregation refers to a phenomenon in cloud‐resolving simulations wherein the atmosphere spontaneously develops a circulation with a convecting moist patch and a nonconvecting dry patch. All previous studies have found a sharp transition to aggregated convection when the domain size exceeds a critical threshold, typically in the range ...

External Drivers and Mesoscale Self‐Organization of Shallow Cold Pools in the Trade‐Wind Regime

Journal of Advances in Modeling Earth Systems
Recent 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 ...

Effect of the Eyewall Cold Pool on the Inner Rainband of a Tropical Cyclone

Journal of Geophysical Research - Atmospheres, 2019
The low‐level cold pool just under a tropical cyclone eyewall and its effect on the formation of inner rainbands are studied, through idealized convection‐permitting simulations.
