Abstract : Meteorological satellites have revealed the need for a major revision of existing climatology of tropical cyclones in the Eastern North Pacific Ocean. The years of reasonably good satellite coverage from 1965 through 1971 provide the data base from which climatologies of frequency, duration, intensity, areas of formation and dissipation and track and speed characteristics are compiled. The climatology of recurving tracks is treated independently. The probable structure of tropical cyclones is reviewed and applied to this region. Application of these climatologies to forecasting problems is illustrated. The factors best related to formation and dissipation in this area are shown to be sea-surface temperature and vertical wind shear. The cyclones are found to be smaller and weaker than those of the western Pacific and Atlantic oceans. (Author)
