New Severe Thunderstorm Radar Identification Techniques and Warning Criteria: A Preliminary Report.

摘要

Improved understanding of severe thunderstorm structure and evolution is used to develop new radar sampling techniques and warning criteria. The only radar data needed are obtained from the conventional National Weather Service radars (WSR-57, WSR-74C and S) when in PPI tilt sequence mode displaying video integrated and processed reflectivities. Actual WSR-57data for six storms are used to exemplify the techniques and criteria.
