Abstract:

Details are given of a computer program that 1 accepts a description of an existing typhoon or tropical storm, 2 searches descriptions of past storms, selects those with similar characteristics and ranks them according to similarity, and 3 prints out subsequent track and storm change data needed by typhoon forecasters. The size, sources and features of the internal typhoon history file are described. During the course of extracting the data, and designing and testing the system, several facets of typhoon data were found to need more research. These include Development of mean or typical storm sea level pressure and 700 mb height profiles with time The recomputation or rejection of inconsistent aircraft reconnaissance data Study of the systematic differences in Navy and Air Force aircraft eye reports Research on diurnal changes within the typhoon eye. Preliminary tests of the computer system show that it will rank the storms and print out the data as instructed, but the predictors will have to be weighted in order to most often select the past storm of most value to the forecaster.
