| 摘 要： | 利用高精度、高时空分辨率、长时间序列的CCMP(Cross-Calibrated,Multi-Platform)风场,驱动国际先进的第三代海浪模式WAVEWATCH-Ⅲ(WW3),得到中国海1988年1月～2009年12月的海浪场。对中国海的波候(风候)进行精细化的统计分析,分析了海表风场和浪场的季节特征、极值风速与极值波高、风力等级频率和浪级频率、海表风速和波高的逐年变化趋势,结果显示:(1)中国海的海浪场与海表风场具有较好的一致性,尤其是在DJF(December,January,February)期间;海表风速和波高在MAM(March,April,May)期间为全年最低,在DJF期间达到全年最大;MAM和JJA(June,July,August)期间,中国海大部分海域的波周期在3～5.5s,SON(September,October,November)和DJF期间为4.5～6.5s。(2)中国海极值风速、极值波高的大值区分布于渤海中部海域、琉球群岛附近海域和台湾以东广阔洋面、台湾海峡、东沙群岛附近海域、北部湾海域、中沙群岛南部海域。(3)吕宋海峡在MAM、SON、DJF期间均为6级以上大风和4m以上大浪的相对高频海域,JJA期间,6级以上大风的高频海域位于中国南半岛东南部海域,4m以上大浪主要出现在10°N以北。(4)在近22a期间,中国海大部分海域的海表风速、有效波高呈显著性逐年线性递增趋势,风速递增趋势约0.06～0.15m.s-1.a-1,波高递增趋势约0.005～0.03m.a-1。

| Abstract: | In this paper,the third-generation wave model WW3(WAVEWATCH-Ⅲ) was used to simulate the wave field of the China Sea from January 1988 to December 2009 with wind input of CCMP(Cross-Calibrated,Multi-Platform) wind field.The wave climate and Wind Climate such as seasonal characteristics,extreme wind speed and wave height,long-term trend of wind speed and SWH(Significant Wave Height) was analyzed,which can apply guidance to waves disaster prevention and reduction,navigation,marine engineering,wave energy development,national defense and so on.Results show that,(1) China Sea wave field and sea surface wind field has a good consistency,especially in DJF(December,January,February).Wind speed and wave height in MAM(March,April,May) for the annual minimum,and in DJF for the annual maximum.During MAM and JJA(June,July,August),wave period in the China Sea is about 3~5.5 s,and 4.5~6.5 s in SON(September,October,November) and DJF.(2) Large areas of extreme wind speed and extreme wave height mainly located in central Bohai sea,water near Taiwan,Ryukyu Islands and East broad ocean,Taiwan Strait,near Dongsha Islands waters,North Bay,Zhongsha Islands off the coast of Southern.(3) High frequency area of gale and big wave mainly located in Luzon Strait in MAM,SON and DJF,in southeastern waters of South Peninsula in JJA.(4) During the last 22 years,sea surface wind speed and wave height in most of the China Sea are significant linear increasing year by year,of 0.06~0.15 m·s-1·a-1 in wind speed and 0.005~0.03 m·a-1 in wave height. |
