State of the Sea Around Tropical Cyclones in the Western North Pacific Ocean

Abstract

The combined sea-height data for the year 1971 for the western North Pacific Ocean are examined to determine the sea-state characteristics around tropical storms and typhoons. The results show that the areal extent about the storms of the combined sea height in the 9-15 ft range is primarily a function of storm duration, intensity (maximum sustained wind) and size. Equations derived by linear regression techniques are presented for describing the state of the sea about tropical cyclones.
