A major uncertainty in weather and climate models lies in the effect of clouds and aerosols. The IPCC's Fifth Assessment Report states that while models include more cloud and aerosol processes, there is still low confidence ...

In the past the best models of raindrop shapes were based on a perturbation form of Laplace's formula valid only for small amplitude distortion from the effect of an aerodynamic pressure around a sphere. In contrast, the ...

The 10-11 June 1985 squall line system with trailing stratiform precipitation observed during the Oklahoma PRE-STORM project has been numerically simulated using the three-dimensional cloud resolving nonhydrostatic COMMAS ...

Non-supercell tornado is a name given to a class of tornadoes which occur with deep moist convection not displaying the strong mid-level rotation found in supercell thunderstorms. In recent years the severe storms community ...

Two high-resolution, two-dimensional numerical models are developed and used to investigate the dynamics of thunderstorm outflows. The first model employs the set of unapproximated, inviscid, fully compressible hydrodynamical ...

The rapid development of a cyclone over Canada and a cold front over the United States were the major weather systems observed on 25-26 April 1979 during the period of SESAME-AVE (Severe Environment Storm and Mesoscale ...

Wind turbines have been shown to impact their local microclimate. With the increasing areal coverage of wind farms it has become increasingly important to answer scientific questions regarding these impacts. In this thesis, ...

The first part of the modeling study was to simulate summertime U.S. precipitation in response to prescribed North Pacific SST anomalies, related to Great Plains precipitation. Summer precipitation is enhanced throughout ...

First GARP (Global Atmospheric Research Program) Global Experiment, Level III-b data and the outgoing longwave radiation data are used to investigate relationships between deep cloud activity and large-scale meteorological ...

The gravity wave was generated behind the leading edge of an advancing dry surge moving over a warm frontal inversion. The dry surge, which had the characteristics of density current, originated as a foehn-like downslope ...
