System and method for detecting and displaying wind shear
First Claim
1. A method of detecting the location of wind shear, said method comprising the steps of:
- detecting radial wind velocities within first and second adjacent gate sweeps of a radar system;
comparing said radial wind velocities within said first gate sweep to adjacent said radial wind velocities within said second gate sweep at points of equal radial distance from said radar system to determine the radial location of gate to gate wind shear between said radar system and the boundary of said radar system'"'"'s range.

Abstract
A computer based method of detecting and displaying rotational wind shear. Radial wind velocities within first and second adjacent gate sweeps produced by a radar system are detected in a predetermined geographic area, and are compared at points of equal radial distance from the radar system. The radial location of gate to gate wind shear at positions between the radar system and the boundary of the radar systems range are identified and compared to a predetermined threshold wind velocity value to determine the location of high priority gate to gate wind shear. The high priority gate to gate wind shear is then graphically displayed relative to its geographic location on a graphical representation of the predetermined geographic area. A computer based system for detecting and displaying rotational wind shear is also disclosed.

9. A system for detecting wind shear, said system comprising:
-
a) a radar system including an antennae having a circumferential coverage area, said antennae positioned in a geographic coverage area to detect radial wind velocities within that coverage area;
b) a database including geographic data corresponding to and representative of the geographic coverage area; and
c) a central processing unit communicating with said radar system to receive information therefrom corresponding to the radial wind velocities, said central processing unit instructed to divide the circumferential coverage area into a plurality of adjacent gate sweeps and to compare radial wind velocities detected in one of said plurality of gate sweeps with radial wind velocities detected in an adjacent gate sweep at locations substantially radially equidistant from said radar system to determine the location of gate to gate wind shear. - View Dependent Claims (10, 11)

12. A method of detecting atmospheric conditions indicative of tornadoes, said method comprising the steps of:
-
a) receiving reflected signals from a radar, said reflected signals including radial wind velocity data for a plurality of adjacent radar gate sweeps;
b) comparing the received radial wind velocity data of first and second adjacent gate sweeps at points of common radial distance from said radar to identify at least one location where there exists a difference in velocities; and
c) associating a shear marker with said at least one location to indicate conditions indicative of a tornado. - View Dependent Claims (13)
