The 1972 Typhoon Analog Program (TYFOON-72)

Abstract

TYFOON, an analog program for the prediction of tropical cyclones in the western North Pacific Ocean, has been in operational use at FWC/JTWC Guam since August 1970. A brief review of TYFOON is presented focussing on its concept, operational results and limitations. Modifications to remedy shortcomings and limitations in the original version are discussed. The modified program TYFOON-72 resulted in the reduction of both computer run time and data storage requirements. Testing and development of the modified program using a sample of 131 forecast situations are reported. TYFOON-72 compared favorably with the official JTWC and TYFOON forecasts at 24 and 48 hr and was superior to both at 72 hr.
