| 摘要: |
| 本文应用东亚地面天气图和西北太平洋海浪实况分析图及沿岸海洋站资料,对8509号台风波浪场进行了分析。并根据台风的强度、移速及外围灭气形势的配合,对台风波浪场进行订正。获得了台风波浪场的分布特征:一、台风移动方向的右半圆的波高大,左半圆小;二、台风波高与风速成正比,而与离开台风中心的距离成反比。另外,应用较简便的方法计算了台风波高,计算波高与实测波高比较,两者较吻合。 |

| ANALYSIS OF WAVE FIELD FOR TYPHOON 8509 |
|
|
| Abstract: |
| 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. |
