A Compilation Of Eastern And Central North Pacific Tropical Cyclone Data PDF Download

Photographic data from TIROS satellites indicate the frequency of tropical cyclones of tropical storm and hurricane intensity, to be some three times greater than the frequency determined by conventional meteorological data in the eastern North Pacific. The sea surface temperatures exert an influence on the size, intensity and track of the cyclones but the dominant influence which prevents a large number of cyclones from being exported into the central Pacific with hurricane force winds is the ''killing'' ef fect of extreme vertical shear as the cyclones pass through the upper tropospheric ridge line. TIROS data are presented to illustrate the ef fects of these influences, separately and in combination, on the life history of eastern Pacific tropical cyclones. (Author).
