The Influence Of Tropical Cyclones On Droughts And Warm Season Precipitation In Tennessee And Kentucky, Lamar S. Coats
The Influence Of Tropical Cyclones On Droughts And Warm Season Precipitation In Tennessee And Kentucky, Lamar S. Coats
Masters Theses & Specialist Projects
The Southeast United States during summer and fall is often affected by droughts and tropical cyclones. Both phenomena rank among the most expensive of natural hazards, although droughts are not as feared by the public as hurricanes. When a tropical cyclone causes a pendulum swing from drought to wet conditions, it is known as a “drought-busting tropical cyclone.” The majority of the research related to drought busting tropical cyclones investigates only the storms during their tropical cyclone phase, which covers the southeastern states that have boundaries adjacent to the Atlantic Ocean. An unanswered question from this literature is whether or …
Application Of The Weather Research And Forecasting (Wrf) Model To Simulate A Squall Line: Implications Of Choosing Parameterization Scheme Combinations And Model Initialization Data Sets, Mitchell Gaines
Masters Theses & Specialist Projects
On January 29-30, 2008 a squall line of thunderstorms moved through the Ohio Valley resulting in four deaths and one injury. Such events highlight the importance of accurate forecasting for public safety. Mesoscale Modeling plays an important role in any forecast of a potential squall line. The focus of this study was to examine the performance of several parameterization scheme combinations in the Weather Research and Forecasting Model version three (WRF) as they related to this event. These examinations included cloud microphysics (WRF Single-Moment 3-class, 6-class, and Goddard), cumulus parameterization (Kain-Fritsch and Bets-Miller-Janjic) and planetary boundary layer schemes (Yonsei-University and …

Precipitation in the Northern Hemisphere has been recently recognized to have hydrogen ion concentrations 10 to 100 times higher than expected for natural precipitation (Likens and Bormann 1974, Cogbill and Likens 1974, Lewis and Grant 1980). However, controversy has arisen regarding the nature of the acidity of the precipitation sampled and whether, indeed, the pH of North American precipitation has increased over time (Miller and Everett 1979, Lerman 1979, Stensland 1980, Sequeria 1981, Carlson and Rodhe 1982). In most locations pH records have been constructed rather imperfectly due to differences in sampling, handling, and analytical procedures used (Galloway and Likens …
