Abstract

Abstract

Based on the Ueosat altimetric data of an ascending orbit over the western Pacific on August 11,1987,the features of sea surface wind and wave under the influence of typhoon Betty are analyzed.It is shown that the spatial distributions of wind speed and wave height are asymmetric to the center of the typhoon.In the direction of the typhoon movement,the wind speed in the right quadrant increased more rapidly than that in the left within the inner area of the typhoon,while in the outer area the former also decreased more rapidly than the latter.However,unlike the wind speed,the spatial distribution of wave height has no obvious division between inner and outer areas.The wave height in the left and right quadrant shows the different distributions with the distance increasing to the typhoon center.The relationships between wind speed and wave height in the right and the left quadrant are obviously different.The empirical formulas are established on the variations in wind speed and wave height with the distance to the typhoon center and on the relationship between wind speed and wave heieht.
