1. A method for predicting the motion of an organized storm, comprising the steps of:
- a) receiving a plurality of weather radar images each being representative of the organized storm during a period of time;
b) applying one or more image filters to each of the plurality of weather radar images to generate one or more filtered weather radar images, wherein the filter has an aspect ratio not equal to one and is substantially matched to the organized storm;
c) providing the filtered weather radar images to an image tracker to generate an array of track vectors; and
d) applying the array of track vectors to a selected unfiltered weather radar image to generate a predicted weather radar image of the organized storm.

Abstract
A method and apparatus for tracking of organized storms using weather radar images. An image filter approximating the envelope of the organized storm radar image is used to improve tracking of the large scale storm features. The image filter is repeatedly rotated to different orientations at each point in the weather radar images to produce filtered images. The filtered images are provided to an image tracker to generate an array of track vectors. Application of the array of track vectors to the unfiltered image generates a predicted weather radar image.
