Geosat satellite altimeter can be extensively used to study front

sea surface wind

wave and altitude etc.

but it is difficult to use altimetric data to analyze the section structures of sea surface wind and wave in typhoon because of the limits of satellite orbit

typhoon track and wind speed algorithm of altimeter etc.. Based on Geosat altimetric data of wind speed and significant wave height in an ascending track on August 11

1987

the sectional distribution characteristics of the wind and wave are analyzed under No. 8708 typhoon. The result shows that the section measuring data can be obtained by altimeters whereas it is difficult to be obtained by conventional methods. Making full use of this information on the characteristics study of sea surface wind and wave structure under typhoon will benifit the prevention of typhoon calamity and the study of air-sea interaction in the synoptic process.
