A Characterization of Cold Pools in the West African Sahel [PDF]
Cold pools are integral components of squall-line mesoscale convective systems and the West African Monsoon, but are poorly represented in operational global models.

Cross Saharan transport of water vapour via recycled cold-pool outflows from moist convection [PDF]
Very sparse data has previously limited observational studies of meteorological processes in the Sahara. We present an observed case of convectively-driven water vapour transport crossing the Sahara over 2.5 days in June 2012, from the Sahel in the south

Pollutant dispersion in a developing valley cold-air pool [PDF]
Pollutants are trapped and accumulate within cold-air pools, thereby affecting air quality. A numerical model is used to quantify the role of cold-air-pooling processes in the dispersion of air pollution in a developing cold-air pool within an alpine ...

Cold‐pool formation in a narrow valley [PDF]
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]
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 ...

Detecting cold pools from soundings during EUREC4A [PDF]
<p>We develop a novel method to detect cold pools from atmospheric soundings over tropical oceans and apply it to sounding data from EUREC<sup>4</sup>A. The proposed method exploits the fact that the air in a cold pool is denser than the air above it. It leads us to define cold pool soundings as those for which

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

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

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.

A pivotal role for starch in the reconfiguration of 14C-partitioning and allocation in Arabidopsis thaliana under short-term abiotic stress. [PDF]
Plant carbon status is optimized for normal growth but is affected by abiotic stress. Here, we used 14C-labeling to provide the first holistic picture of carbon use changes during short-term osmotic, salinity, and cold stress in Arabidopsis thaliana ...
