Objective and Dynamic Analyses of Tropical Weather.
Abstract
Preliminary results from a study on determining atmospheric motions from ATS-3 Satellite cloud photographs are presented. Using recently developed methods for measuring cloud displacements from two or more photographs, it has been possible to obtain cloud-motion data that give a relatively dense and continuous spatial coverage of the Caribbean. Thus, the ATS type photographs should provide significant amounts of tropical data for incorporation into objective analysis and prediction schemes. A numerical method has been developed for estimating the wind-speed field given only the streamline field (deduced from satellite data) and actual wind-speed values at the boundaries. The method has been tested using actual wind-vector fields and has been found to provide wind-speed distributions that are reasonably similar to the actual speed distributions. A brief description is given of a number of computer forecasting techniques that are to be tested on tropical wind analyses. (Author)
