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, ...

In this thesis, investigations on gravity waves are conducted in two regions of the middle atmosphere: the lower stratosphere using high-resolution radiosonde at South Pole and the mesopause region using OH airglow ...

The goal of the present research was to investigate the low frequency modes of variability in the observed atmosphere and compare those to the counterpart modes in a Global Climate Model (GCM). As a means to accomplish ...

The climate in Pakistan is characterized by distinct summer and winter south Asian monsoon systems. As Pakistan locates at the transit zone from central to southern Asia, its climate variability is subject to planetary ...

Extreme events, including precipitation extremes, can have severe impacts on human society and on ecosystems. In the late 20th century, heavy precipitation events tend to occur with increasing frequency or intensity ...
