An Automated Objective Technique For Constructing Tropical Cyclone Best Tracks

Abstract

A computerized objective technique has been developed to assist in the construction of tropical cyclone postanalysis tracks. The program employs linear and second-order smoothing routines to calculate storm position and intensity histories. The technique is general in nature and can incorporate fix information from any of the usual tropical cyclone reconnaissance platforms. It is currently undergoing evaluation at the Fleet Weather Central/Joint Typhoon Warning Center on Guam, Marianas Islands, as an aid in the development of best tracks for the western North Pacific Ocean and Bay of Bengal tropical cyclones.
