根据卫星高度计资料的特点 ,在对 3个海洋站的海浪极值推算中引用发展了尾部分布增强法 (Tail Distribution Method) ,并且与 3个海洋站实测资料推算结果相比较 ,结果良好。以此为基础对西北太平洋进行多年一遇极值推算 ,其多年一遇的极值分布与风场的分布是一致的 ,主要呈纬向带状分布特征 :从 35°N～ 55°N,1 4 5°E～ 1 80°E的长方形海域 ,长时间受到季风的作用并且海域开阔 ,所以它的百年一遇波高可以达到 1 3m以上 ;而在赤道无风带控制下的海域 ,它的百年一遇波高一般为 7m左右。
According to the characteristics of the satellite altimeter data, Tail Distribution Method was developed in the calculation of the ocean wave extremum of 3 ocean stations. Compared with the results of 3 ocean stations, the result is good. Based on this, the extreme value prediction of the Northwest Pacific Ocean is carried out on a yearly basis. The distribution of the extreme value of the annual distribution is consistent with that of the wind farm. The distribution is mainly zonal zonal distribution: from 35 ° N to 55 ° N, Its rectangular sea area from 1 45 ° E to 1 80 ° E is affected by the monsoon for a long time and its sea area is open, so its wave height in a century can reach more than 13 meters. In the sea under the control of the equatorial wind-free zone, its One hundred years wave height is generally about 7m.
