1. A weather hazard detection apparatus comprising:

  • a plurality of SENSTRANS units positioned at spaced intervals in an area in which weather hazards are to be detected, each SENSTRANS unit including;

    a humidity sensor,a wind speed sensor,a wind direction sensor,a barometric pressure sensor,a temperature sensor, andmeans for transmitting measurement values from said sensors via RF transmission at predetermined intervals,a data processing and display unit (DAPAD), said DAPAD comprising,means for receiving said measurement values transmitted by said SENSTRANS units,means for storing said values along with an identification of the particular SENSTRANS unit from which it originated and the time period in which it was measured,a data processing unit for manipulating said stored measurement values to calculate parameters indicative of the presence or absence of weather hazards, said manipulations including, at least, calculation of the time differential of the equivalent potential temperature for at least one point in said area,said DAPAD further including means for generating a warning signal responsive to one or more of said calculated parameters falling within corresponding predefined ranges indicative of the likely presence of a weather hazard, anddisplay means responsive to said warning signal for producing a display indicating the presence of a weather hazard.
