ANALYSIS OF WAVE FIELD FOR TYPHOON 8509
8509号台风波浪场的分析

With the wave-analysis data of the Northwest Pacific Ocean and that from the coastal stations, the authors analysed the wave-field of the typhoon 8509 and did some corrections on the wave-field according to the strength and velocity of the typhoon and its relation with periphery weather system. The distributional features of the wave field are thus obtained: the wave heights of the right hemicircle of the typhoon are greater than ones of the left; the wave heights are directly proportional to the wind velocity and inversely proportional to the distance from the centre of typhoon. The wave heights computed by a simple method agree well with observed heights.
