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。
This paper analyzes the 8509 typhoon wave field by using the East Asia surface weather map, the Northwest Pacific Ocean wave factogram and the coastal ocean station data. The typhoon wave field is revised according to the strength of the typhoon, the speed of movement and the situation of the external air extermination. The distribution characteristics of the typhoon wave field are obtained. First, the right semicircular wave in the moving direction of the typhoon is large and the left semicircle is small. Second, the typhoon wave height is proportional to the wind speed and inversely proportional to the distance from the typhoon center. In addition, the typhoon wave height is calculated by a relatively simple method, and the calculated wave height is in good agreement with the measured wave height.
