Forecast Verification and Reconnaissance Data for Southern Hemisphere Tropical Cyclones

This report documents tropical cyclones which developed in the South Indian Ocean and South Pacific Ocean from 1 July 1982 to 30 June 1984. It provides composite storm best-tracks, a brief summary of each year's tropical cyclone season, and detailed position and reconnaissance fix data. In addition, this report contains forecast accuracy statistics for Southern Hemisphere tropical cyclones. A total of 55 tropical cyclones reached warning status in the combined Joint Typhoon Warning Center and Naval Western Oceanography Center area of responsibility between 1 July 1982 and 30 June 1984. Twenty-five attained warning status in the 1982-1983 season, with thirty reaching warning status in the 1983-1984 season. Intensity estimates for Southern Hemisphere tropical cyclones are derived primarily from satellite imagery evaluation (Dvorak, 1973) and from intensity estimates reported by other regional warning centers. In very rare instances, the intensity estimates are based on surface observational data. Estimates of the minimum sea-level pressure are usually derived from the Atkinson and Holliday (1977) relationship between the maximum sustained one-minute surface wind and the minimum sea-level pressure.
