A Statistical Model To Forecast Short-Term Atlantic Hurricane Intensity, Kevin Law, Jay S. Hobgood
A Statistical Model To Forecast Short-Term Atlantic Hurricane Intensity, Kevin Law, Jay S. Hobgood
Geography Faculty Research
An alternative 24-h statistical hurricane intensity model is presented and verified for 13 hurricanes during the 2004–05 seasons. The model uses a new method involving a discriminant function analysis (DFA) to select from a collection of multiple regression equations. These equations were developed to predict the future 24-h wind speed increase and the 24-h pressure drop that were constructed from a dataset of 103 hurricanes from 1988 to 2003 that utilized 25 predictors of rapid intensification. The accuracy of the 24-h wind speed increase models was tested and compared with the official National Hurricane Center (NHC) 24-h intensity forecasts, which …

Environmental Disturbance And The Distribution Of Rhinichthys Bowersi In West Virginia, Brooke Elizabeth Schlenker
Theses, Dissertations and Capstones
The Cheat minnow, Rhinichthys bowersi, has been designated a species of concern by the West Virginia Department of Natural Resources. Mitochondrial DNA analysis (Gladwell 2002) supports the origin of R. bowersi from hybridization between cyprinids R. cataractae and Nocomis micropogon. Previous investigators have hypothesized a relationship between fish hybridization and environmental disturbance. The habitat of R. bowersi has experienced severe environmental degradation from mineral and timber extraction. In this study, environmental quality was compared between stream systems in which parental species of R. bowersi were found with and without resulting hybridization. Environmental quality indicators included biotic diversity and stream structure …
