PCT No. PCT/US97/01389 Sec. 371 Date Jul. 27, 1998 Sec. 102(e) Date Jul. 27, 1998 PCT Filed Jan. 29, 1997 PCT Pub. No. WO97/28460 PCT Pub. Date Aug. 7, 1997A weather radar system (21) utilizing enhanced fuzzy logic processing (300) to detect atmospheric microburst events. In addition to the wind shear likelihood (250), low level surface reflectivity likelihood (252), and clutter likelihood (254) used by existing fuzzy logic based microburst detection systems to generate a combined microburst likelihood, one enhancement includes using reflectivity measurements of high level storm activity to generate an independent high level aloft reflectivity likelihood image (310) that corresponds to and confirms the findings of the low level surface reflectivity likelihood (252). Another enhancement includes using a series of combined likelihoods saved over time (635) for N successive scans of the weather radar system (21) to generate a history likelihood (620) that eliminates spurious detections from one scan to the next. Another enhancement includes generating a microburst strength determination (330) based on the wind speed loss an aircraft would experience when flying through a microburst.
