WSR-88D Approach to Waterspout Forecasting

摘要

This paper will begin by providing a brief overview of the waterspout formationprocess. It also offers a forecast strategy developed for the east-central Florida coast using specific WSR-88D products to recognize precursor signatures to waterspout and weak tornado formation. Once a high potential for waterspout formation exists, a special statement can be issued to heighten public awareness. An example of such a statement is provided. The WSR-88D is being installed at National Weather Service (NWS) forecast and warning offices and many military installations across the country. The added capabilities of the WSR-88D over conventional radar provides the forecaster a multitude of products which allow a more complete investigation of small scale weather features. While the techniques introduced here were designed for the east-central Florida coast, they may be applicable at other coastal offices equipped with the WSR-88D.
