Abstract
航海、防止和减少海浪灾害、海洋工程等对大浪发生的频率(简称大浪频率)极为关注，大浪对人类的生产、生活往往造成严重影响，甚至带来灾害，深入研究中国海的大浪频率具有重要的实用价值。本文利用CCMP (Cross-Calibrated, Multi-Platform)风场，驱动目前国际先进的第三代海浪模式WW3 (WAVEWATCH-III)，模拟得到了1988~2011年逐3小时的中国海海浪场，并利用Grads (Grid Analysis and Display System)软件，结合Fortran程序，统计了中国海2.0 m以上大浪、4.0 m以上大浪出现的频率，希望该方法可以为相关统计工作提供参考，结果可以为航海、海洋工程等提供参考。Sailing, disaster prevention and reduction, and ocean engineering are extremely concerned about the frequency of big wave (shorten as big wave frequency). The big wave often has a great effect on the produce and life of human society, even disaster. The deep research on the frequency of big wave is very necessary. In this study, we used CCMP (Cross-Calibrated, Multi-Platform) wind field to drive WW3 wave model to simulate the China Sea wave field. A 3-hourly wave field in the China Sea from 1988 to 2011 is obtained. Then the Grads (Grid Analysis and Display System) and Fortran were used to statistics the frequency of the China Sea big wave frequency, based on the simulation wave data. We mainly statistics the frequency of significant wave height greater than 2.0 m, and significant wave height greater than 4.0 m. The result can provide reference for navigation, ocean engineering, prevent and reduce sea wave calamity, and so on.
