Microphysical Influences on cold pools
… convective clouds to the ground can produce cold pools, regions of air at the surface cooled by melting or sublimating ice and/or evaporation of rain within the downdrafts. These cold pools can propagate outward, sometimes initiating new convection along their leading edges. Models operating …

Mineral dust lofting and interactions with cold pools
… the complex and non-linear interactions between cold pools, dust radiative effects, and land surface processes, and their associated uncertainties in numerical models. In this dissertation, model simulations of real and idealized haboobs are used to address limitations in regional dust modeling, …

Tropical oceanic mesoscale cold pools in observations and models
Convective cold pools over oceans contribute to the atmosphere-ocean exchange of heat and moisture across the globe. Beyond cold pools’ physical properties, cold pools and their intersections are important mechanisms controlling the life cycle of tropical convective systems. However, few …

Understanding precipitation, cold pools, and cloud arcs in the tropics
… model v3.3.1 to do idealized simulations of a cold pool outflow boundaries in a tropical marine cumulus environment. We are modeling cold air downdrafts and resulting surface cold pools that are thought to cause the arc-shaped cumulus clouds. In idealized sensitivity tests of tropical cumulus …

Dynamics of downdruaghts and cold pools: an experimental and numerical study
Downward moving cold air within a thunderstorm, known as a downdraught, can be an additional storm hazard, and also prolong the convective lifecycle. An understanding of downdraughts is therefore useful for weather forecasting. Typically, in weather forecasting downdraughts are modelled using the …

Effects of Microphysical Parameterizations and Drop Breakup on Supercells and Supercell Cold Pools.
… parameterizations affect the supercell cold pool and the evolution of storm structure. Using in-situ data gathered by StickNet probes, the simulated cold pool can be objectively verified against the observations. This verification is done over the entire supercell and over the two main …

How does terrain influence the upscale convective growth of orographic deep moist convection?
… strong downdrafts and expansion of the cold pool resulted in a rapid transition to a bowing mesoscale convective system. Terrain height sensitivity experiments were conducted with only the control and higher terrain experiments resulting in a supercell-to-bowing mesoscale convective …

Formation and maintenance of tropical cyclone spiral bands in idealized numerical simulations
… and the interaction between surface cold pools and low-level vertical wind shear. Despite much effort, no consensus has yet been reached on the underlying physical mechanism responsible for TC bands. We approach this problem by examining the formation of TC spiral bands in a set of …

A numerical modeling investigation of entrainment in cumulus congestus clouds and its effects upon precipitation
… clouds revealed the importance of interacting cold pools in forcing subsequent generations of convection. Substantial moistening of the locally entrained air into the later generations served to protect the clouds from dilution and enhanced the warm rain process.

Downdraft impacts on tropical convection
… important mass flux in all simulations, and that cold pools organize convective systems and enhance updraft Convective Available Potential Energy (CAPE). We examine the ability for downdrafts to help couple deep convection to high relative-humidity regions in the tropics, and find that entrainment …
