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.

Sensitivity of Deep Ascent of Cold-Pool Air to Vertical Shear and Cold-Pool Buoyancy

E-Journal of Severe Storms Meteorology, 2021
The tilting and stretching of solenoidally generated vorticity that is hypothesized to be a necessary condition for supercell tornadogenesis is predicated on the presence of ascent of cold-pool air. Results are presented from experiments designed to test the sensitivity of this ascent to the temperature deficit of the cold pool and the environmental ...

Cold‐pool formation in a narrow valley [PDF]

Quarterly Journal of the Royal Meteorological Society, 2013
AbstractA numerical model simulation of the formation of a cold pool within a narrow valley during a clear calm night is presented. The results are compared with measurements made during the COLd air Pooling EXperiment (COLPEX). It is demonstrated that the model provides a realistic simulation of the observed cold pool.

Cold pools mediate mesoscale adjustments of trade-cumulus fields to changes in cloud droplet number concentration [PDF]

Atmospheric Chemistry and Physics
The mesoscale self-organization of trade-cumulus cloud fields is a major cloud–climate uncertainty. Cold pools, i.e., pockets of cold, dense air resulting from rain evaporation, are a key mechanism in shaping these dynamics and are controlled by the ...

Enjoying the outdoor pool in a cold climate [PDF]

Geothermal Energy, 2017
Background: The article explores the significance of abundant geothermal resources Icelanders enjoy, the comfort of inexpensively heated homes and easily accessible year-round public spaces where young and old can gather irrespective of social standing, age and bodily condition. Result: In recent decades, the outdoor public swimming pool has become the

Common Marginal Cold Pools

Journal of Applied Meteorology and Climatology, 2015
AbstractThis study examines marginal cold pools forming in a shallow valley. “Marginal” refers to cold pools that are generally weak and intermittent. Nineteen stations were instrumented with sonic anemometers and accurate slow-response temperature measurements. The vertical structure of the cold pool is determined from a 20-m tower on the valley floor

Cold pool train dynamics and transport

, 2023
Convectively generated cold air outflows, referred to as cold pools, can initiate new convection and loft aerosols, such as dust or pollen. In the BioAerosols and Convective Storms Phase I (BACS-I) field campaign, we observed multiple cold pools passing over the same location on the same day, without colliding, which we refer to as a "cold pool train".

Mechanisms of Convective Clustering During a 2‐Day Rain Event in AMIE/DYNAMO

Journal of Advances in Modeling Earth Systems, 2020
Physical mechanisms that are key to observed convective clustering in 2‐day rain events are examined. Previous analysis of the 2‐day rain events during the Atmospheric Radiation Measurement Madden‐Julian Oscillation Investigation Experiment (AMIE ...

Estimating Nitrogen Release from Organic Fertilizers for Soilless Production by Analysis of C and N Pools

Horticulturae, 2023
The use of organic fertilizers in soilless pot plant production has sharply increased in recent years. However, there is still a lack of methods for characterizing the N release from organic fertilizers.

Trade Wind Boundary Layer Turbulence and Shallow Precipitating Convection: New Insights Combining SAR Images, Satellite Brightness Temperature, and Airborne In Situ Measurements

Geophysical Research Letters, 2023
The imprint of marine atmospheric boundary layer (MABL) dynamical structures on sea surface roughness, as seen from Sentinel‐1 synthetic aperture radar (SAR) acquisitions, is investigated. We focus on 13 February 2020, a case study of the elucidating the
