System and method for projecting storms using NEXRAD attributes
DCFirst Claim
1. A method of using NEXRAD attributes to project a path of a storm for graphical display, said method comprising the steps of:
- (a) collecting a plurality of NEXRAD attributes corresponding to a storm and storing said plurality of NEXRAD attributes in a first database;
(b) deriving a storm position in latitude and longitude from a first selected group of said plurality of stored NEXRAD attributes;
(c) calculating a projected storm path using said derived storm position and a second selected group of said plurality of stored NEXRAD attributes;
(d) displaying a graphical representation of said projected storm path, said projected storm path comprising a storm projection arc defining the boundary of said projected storm path by latitude and longitude;
(e) retrieve geographical data stored in a second database by latitude and longitude, said geographical data comprising at least one area of interest including a plurality of populated areas; and
(f) comparing said plurality of populated areas to said storm projection arc to determine which of said plurality of populated areas fall within said storm projection arc.

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 data base 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.

13. A system using NEXRAD attributes to project a path of a storm for graphical display, said system comprising:
-
a) a first database comprising a plurality of extracted NEXRAD attributes, said NEXRAD attributes comprising a first group of data and a second group of data; b) a second database comprising geographical data stored by latitude and longitude, said geographical data including at least one area of interest defining a plurality of populated areas defined by latitude and longitude; c) a CPU communicating with said first database to calculate a storm position in latitude and longitude from said first group of data, said CPU combining said calculated storm position with said second group of data to calculate a projected storm path, said projected storm path comprising a storm projection arc, and communicating with said second database to compare said plurality of populated areas with said storm projection arc to determine which of said plurality of populated areas fall within said storm projection arc; and d) a display device communicating with said CPU to graphically display said plurality of populated areas falling within said storm projection arc.
