Analysis of energy conserving low-order models.
(2007)
It is well known in Mathematical Physics that the Volterra gyrostat and many of its special cases including the Euler gyroscope represent a prototype of energy conserving dynamical systems. It is formally proved in this ...
Investigation of polarimetric measurements of rainfall at close and distant ranges.
(2007)
As part of continuous modernization of operational weather radar systems, several government agencies have explored adding polarimetric capability to existing networks. Polarimetric measurements of rain have been previously ...
Responses of soil respiration and ecosystem productivity to climate change in southern Great Plains.
(2007)
The third is to investigate the role of precipitation on ecosystem carbon processes (i.e., biomass, litterfall, and soil respiration) along a natural precipitation gradient in southern Great Plains. Our results show that ...
Retrieval of moisture from GPS slant-path water vapor observations using 3DVAR and its impact on the prediction of convection initiation and precipitation.
(2007)
The anisotropic explicit filter is computationally expensive in both CPU time and memory usage. Therefore the implicit recursive filter which is computationally much more efficient is implemented in our 3DVAR system, even ...
High resolution simulations of the microphysics and electrification in hurricane-like vortices over warm ocean and at landfall.
(2007)
Cloud-to-ground (CG) lightning bursts in the eyewall of mature tropical cyclones (TCs) are believed to be good indicators of imminent intensification of these systems. While numerous well-documented observational cases ...
Characteristics of tropical cyclones in the North Atlantic and East Pacific.
(2007)
In this dissertation, I present a series of investigations to expand our understanding of TCs in the East Pacific and North Atlantic basins. First, I developed and applied a climatological tool that quickly and succinctly ...
Spectral analyses of the dual polarization Doppler weather radar data.
(2007)
Echoes in clear air from biological scatterers mixed within the resolution volumes over a large region are presented. These echoes were observed with the polarimetric prototype of the forthcoming WSR-88D weather radar. The ...
