On the Sensitivity of Convective Cold Pools to Mesh Resolution
Journal of Advances in Modeling Earth Systems, 2022 Abstract 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 cumbersome—in part due to the lack of numerical convergence

Mechanical Forcing of Convection by Cold Pools: Collisions and Energy Scaling
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

Simulation of Mesoscale Convection Process into Sea Based on Downscaling Method
应用气象学报, 2022 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 ...

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.

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 ...

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

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.
