1. A method of identifying the presence and locus of wind shear in a predefined area based on wind measurements taken at a plurality of wind sensing loci located in said predetermined area, each of said measurements being indicative of a wind magnitude and direction at a corresponding one of said loci said method comprising the steps of:

  • collecting said wind measurements from said plurality of loci;

    producing wind shear shape data indicative of the bounds of a wind shear event within said predetermined area based on said collected wind measurements to identify the presence and locus of wind shear in said predefined area, comprising;

    creating a grid having a plurality of points that maps said predetermined area into said plurality of points,converting each of said wind measurements taken at said plurality of wind sensing loci into divergence values indicative of wind divergence at each of said plurality of wind sensing loci, as computed between selected pairs and triples of said wind sensing loci;

    mapping each of said divergence values onto said grid to create corresponding wind data points, each of which has a value representative of a wind divergence at a corresponding one of said plurality of points in said predetermined area,deleting all said mapped wind data points whose mapped value does not exceed a predetermined threshold from said grid, andbounding all contiguous ones of said mapped wind data points that remain in said grid following said step of deleting within a boundary of predetermined shape to identify the presence and locus of a wind shear event.
