System and method for detecting and displaying wind shear
First Claim
1. A computer based method of detecting and displaying rotational wind shear, said method comprising the steps of:
- a) detecting radial wind velocities within first and second adjacent gate sweeps produced by a radar system positioned in a predetermined geographic area;
b) 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;
c) identifying the radial location of gate to gate wind shear between said radar system and the boundary of said radar system'"'"'s range;
d) comparing the identified gate to gate wind shear to a predetermined threshold wind velocity value to determine the location of high velocity gate to gate wind shear; and
e) graphically displaying the geographic location of the high velocity gate to gate wind shear relative to a geographic representation of the predetermined geographic area in graphical form.

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.
