Severe weather detection, classification and localization using dual-polarization radar
First Claim
1. A system that predicts the occurrence and location of a severe weather event comprising:
- a. one or more processors;
b. a non-transitory tangible media containing software or firmware encoded thereon for operation by the one or more processors that receive a plurality of weather variables, at least one of said weather variables being from radar data from a dual-polarization radar;
where the one or more processors are configured (i) to generate at least one derived radar variable based on the weather variables, (ii) to identify at least one geographic region of interest by determining if the at least one derived radar variables is indicative of a potential severe weather event in the geographical area, (iii) to validate the presence of the geographic region of interest by validating the presence of at least one of a tornado debris signature, a hail core, a region of high shear or a tornado vertex therein, (iv) to determine whether there is a vertical column of regions of interest within the geographic of interest, wherein the presence of the vertical column of regions of interest is indicative of the vertical size of the severe weather event, (v) to validate the presence of the vertical columns of regions of interest by scoring each column by applying a test to a set of features of the vertical columns of interest, and (vi) to display a graphical representation of the location of the severe weather event.

Abstract
The present disclosure provides a system that predicts the occurrence and location of a severe weather event including a non-transitory tangible media containing software or firmware encoded thereon for operation by one or more processors that receive a plurality of weather variables, at least one of said weather variables being from radar data from a dual-polarization radar, where the processor (i) generates at least one derived radar variable based on the weather variables, (ii) identifies a geographical region of interest, (iii) validates the presence of the region of interest, (iv) determines whether there is a vertical column of regions of interest, wherein the presence of the vertical column of regions of interest is indicative of the vertical size of the severe weather event and (viii) validates the presence of the vertical columns of regions of interest.

13. A computer implemented method of determining the existence of a severe weather event comprising the steps of:
-
a. collecting radar data from a dual-polarization radar, said radar data comprising a weather variable; b. processing the radar data to determine at least one derived radar variable; c. identifying a geographic region of interest by determining if the at least one derived radar variable is indicative of the existence of a severe weather event in the geographic region of interest; d. validating the presence of at least one of a tornado debris signature, a hail core, a region of high shear or a tornado vertex within the geographic region of interest; e. identifying vertical columns of regions of interest within the geographic region of interest; f. validating the presence of the vertical columns of regions of interest by scoring each column by applying a test to a set of features of the vertical columns; and g. displaying a graphical representation of the location of the severe weather event. - View Dependent Claims (14, 15, 16, 17, 18)
