Mesoscale convective systems (MCS) contribute about half of the world's precipitation and create flash flooding as well as other extreme weather events. Despite steady progress in research of these systems in the last several decades, better theoretical ...

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.

In an overall approach aiming at the development and qualification of various tools designed to diagnose and/or forecast the flows at the local scale in complex terrain, we qualified a numerical model based on the WRF platform and operated in a two-way ...

Simulation of Mesoscale Convection Process into Sea Based on Downscaling Method
Two processes of mesoscale convection moving eastward into the Bohai Bay on 12 May and 13 Jul in 2018, which are weakened process and enhanced process respectively, are simulated and analyzed by using the ocean-atmosphere-wave coupling model and dynamic ...

Enjoying the outdoor pool in a cold climate [PDF]
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

Analysis of Controlled Driving and Spreading Behavior of Molten Pool in Cold Metal Transfer
The controlled short-circuit transfer is used to control the heat input of the molten pool and the base metal in the cold metal transfer welding process, including droplet formation, droplet transfer and molten pool flow.

Mechanisms for convection triggering by cold pools [PDF]
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.

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
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".
