Background It is necessary for operational meteorologists to forecast quickly and accurately when storms have the potential of producing severe weather such as tornadoes or hail. Presently, radar represents the most effective way to monitor storms in real time. The National Weather Service recently upgraded the national radar network to polarimetric capability. Much time and resources have been devoted to understanding the development of Great Plains supercells such that polarimetric radar schematics have been developed for them. Little, however, has been done for tropical cyclone supercells. In this study we wish to determine typical polarimetric radar structure for supercells in tropical cyclones.

Objectives: Determine typical polarimetric radar signatures of supercell thunderstorms in tropical cyclones. -- Compare and contrast our findings with the typical polarimetric radar signatures of Great Plains supercells. -- Assess how to use polarimetric observations to better forecast severe weather threats in tropical cyclone supercells
