Patent Images
1. A method for a computer-assisted prediction of near-term development of convective meteorological events comprising the steps:
- (a) determining a difference image by advecting a first meteorological image and combining the advected first meteorological image and a second meteorological image, the first and second meteorological images each comprising data indicative of a first forecast parameter at a first time and a second time, respectively;
(b) generating an interest image comprising a region of interest by filtering a third meteorological image; and
(c) generating a growth image indicative of the occurrence of a convective meteorological event by combining the difference image and the interest image.

Abstract
A method and apparatus for forecasting the likely occurrence of convective weather events, such as thunderstorms. An image filter is used to identify areas of interest within a meteorological image that are likely to contain convective weather. The image filter and an image difference processor identify areas within the meteorological image that are likely to experience a growth and/or decay of weather events. The meteorological image, interest image and growth/decay image are processed to produce the short-term forecast.
