The Trajectories of Dropsondes in Simulated Thunderstorm Circulations
TLDR
In this paper, the trajectories of hypothetical dropsondes are calculated in thunderstorm circulations and resultant vertical wind speed profiles as a function of height are constructed for each of the sondes.Abstract:
The trajectories of hypothetical dropsondes are calculated in thunderstorm circulations and resultant vertical wind speed profiles as a function of height are constructed for each of the sondes. Motion fields are a) calculated by a time-dependent two-dimensional thunderstorm model and b) constructed based upon observed environmental winds. Model-calculated vertical wind speed profiles are compared with observations for the northeastern Colorado storm of 22 July 1972. Agreement is shown between certain basic features; additionally, other calculations point to various potential features of dropsonde trajectories and vertical wind speed profiles. Possible application of similar methods to the hail growth problem is discussed.read more

The Sensitivity of Convective Initiation to the Lapse Rate of the Active Cloud-Bearing Layer
Adam L. Houston,Dev Niyogi +1 more
TL;DR: In this article, the authors used an idealized cloud-resolving model to explore the sensitivity of deep convective initiation (DCI) to the lapse rate of the active cloud-bearing layer [ACBL; the atmospheric layer above the level of free convection (LFC)].

The application of a 2-D convective cloud model to waste heat release from proposed nuclear energy centers
TL;DR: In this paper, a two-dimensional time-dependent convective cloud model is applied to the problem of atmospheric effects from latent and sensible heat releases by nuclear energy centers, where the horizontal extent and strength of the source (perturbation) is consistent with those proposed for such centers.

High-Wind Drag Coefficient Based on the Tropical Cyclone Simulated With the WRF-LES Framework
TL;DR: In this paper, the authors evaluated the drag coefficient of the boundary wind profile for the vertical exchange of horizontal momentum between the atmosphere and the ocean, and found that the effect of the TC-ocean interaction on the resulting drag coefficient increases with the increasing near-surface wind speed.
