Comparison Of A Conceptual Model And Objective Indicators Of Extratropical Transition In The Western North Pacific, Gregory D. Fox
Comparison Of A Conceptual Model And Objective Indicators Of Extratropical Transition In The Western North Pacific, Gregory D. Fox
Theses and Dissertations
The primary purpose of this research is to provide guidance to forecasters from the Joint (Air Force/Navy) Typhoon Warning Center (JTWC) in Pearl Harbor to use in differentiating between the stages of extratropical transition (ET) of tropical cyclones (TCs). Not only is ET relevant to the Department of Defense, since JTWC stops providing TC warnings once they have undergone ET, but it is also applicable to the meteorological community since there currently "is no commonly accepted definition of ET" (Jones et al 2003). This research compares the results of a conceptual model of ET using subjective satellite analysis with the …
Feasibility Of Using Classification Analyses To Determine Tropical Cyclone Rapid Intensification, Jonathan W. Leffler
Feasibility Of Using Classification Analyses To Determine Tropical Cyclone Rapid Intensification, Jonathan W. Leffler
Theses and Dissertations
Tropical cyclone intensity techniques developed by Dvorak have thus far been regarded by tropical meteorologists as the best identification and forecast schemes available using satellite imagery. However, in recent years, several ideologies have arisen which discuss alternative means of determining typhoon rapid intensification or weakening in the Pacific. These theories include examining channel outflow patterns, potential vorticity superposition and anomalies, tropical upper tropospheric trough interactions, environmental influences, and upper tropospheric flow transitions. It is now possible to data mine these atmospheric parameters thought partly responsible for typhoon rapid intensification and weakening to validate their usefulness in the forecast process. Using …
