System and method for projecting storms using NEXRAD attributes
First Claim
1. The method of processing meteorological data, said method comprising the steps of:
- receiving NEXRAD attribute data corresponding to a storm position relative to a radar site;
deriving from said NEXRAD attribute data a storm location relative to a viewing area the center of which is remote from the radar site; and
calculating a projected storm path using said derived storm location and said NEXRAD attribute data.

Abstract
The subject invention provides an improved system and method for combining data obtained from the NEXRAD™ system of the National Weather Service (“NWS”) with geographical and topological database information to achieve an improved and informative graphical storm-tracking display able to project the movement of a storm with a single user-operation. The method of projecting storm movement includes the following steps: collecting NEXRAD data attributes from a weather data source; calculating storm position using the collected NEXRAD attributes; calculating projected storm movement using the storm position and the collected NEXRAD attributes; displaying a graphic representation of the projected storm movement.
