Tropical Cyclone Forecast Verification as a Function of Reconnaissance Platform.
Abstract
Harrison (1975) examined tropical cyclone forecast accuracy as a function of the reconnaissance platform used as the basis for each forecast's initial position. Using 1973 and 1974 data, Harrison showed that forecasts based on aircraft position fixes were most accurate. This paper used data collected from 1977-1979 to update Harrisons's study. The present analysis shows that, overall, tropical cyclone initial positions and forecasts based on aircraft positions fixes were most accurate when compared to the Joint Typhoon Warning Center's best tracks. Unlike the earlier study, forecasts based on satellite reconnaissance were more accurate than forecasts based on aircraft reconnaissance for tropical cyclones which never reached typhoon intensity.
