Southeast U.S. Cold Season Severe Thunderstorm Environments and Their Depictions Using Multiple Planetary Boundary Layer Parameterization Schemes
(2015-12-18)
The primary motivations of this dissertation are to identify meteorological characteristics of the southeastern United States cold season tornado environment and to improve numerical modeling of such environments focused ...
Analysis of the Dynamics and Microphysics of a Wet Downburst Case Using Dual-Polarization Radar Data
(2019-05-10)
A significant, wet downburst affected Norman, Oklahoma, on 14 June 2011. Surface winds in excess of 35 m/s (>80 mph) and hailstones in excess of 4 cm diameter occurred during the downburst. The polarimetric S-band (~11.09-cm ...
A Polarimetric and Microphysical Investigation of Winter Storms
(2018-12)
The U.S. WSR-88D network has been upgraded to polarimetric capabilities, providing dual-polarization data for regions of the country never before sampled by polarimetric radar and allowing for an unprecedented view into ...
Machine Learning Predictions of Flash Floods
(2016-08-12)
This dissertation contains a literature review and three studies concerned with the development, assessment, and use of machine learning (ML) algorithms to explore automatically generated predictions of flash floods. The ...
Observational and model analyses of the Oklahoma City urban heat island
(2014-05-09)
To date, much of the current understanding of the impacts of urban areas on atmospheric processes results from a number of field programs. Between 28 June and 31 July 2003, a vast array of instrument systems collected ...
Near Surface Atmospheric Impacts Resulting From a Developing Metropolitan Area
(2016-12)
Over the past century, the population of the world has become increasingly urbanized. As a result, cities have become larger and more densely populated than any time in history. This unprecedented growth and rapid modification ...
The Changing Hydroclimate of the United States Great Plains: Meteorological and Climatological Impacts on Water Resources
(2018-12-14)
In the United States Great Plains (GP), understanding precipitation variability is key in developing an understanding of the present and future availability of water in the region. Numerous studies have investigated the ...
A MOBILE RADAR BASED CLIMATOLOGY OF SUPERCELL TORNADO STRUCTURES AND DYNAMICS
(2010)
Fine-scale-resolution mobile radar observations of supercell tornadoes have been collected by the Doppler On Wheels (DOWs) platform between 1995 and 2010. The result of this ongoing effort is a large observational database ...
Impacts of tropopause polar vortices on Arctic sea ice loss
(2019-05)
The Arctic and sea ice cover play fundamental roles in the environment of the Earth system. Improved causal understanding of their changes is needed for meaningful predictions and planning. Among the linkages composing our ...
RADAR POLARIMETRY FOR BIOLOGICAL APPLICATIONS
(2015-05-08)
Radar aeroecology has steadily progressed since its inception in the 1950's, and additional advancements in radar technology, networks, modeling, and validation continue to drive the science further. As human impacts ...
