摘要

摘要: 基于国际先进的第三代海浪数值模式WAVEWATCH -Ⅲ,以CCMP风场为驱动场,模拟得到中国海域域1988年1月-2010年12月的海浪场。从提高波浪能资源利用效率的角度出发,定义了波浪能资源开发的有效时间,综合考虑波浪能流密度的大小、资源开发有效时间出现的频率、能流密度的稳定性(变异系数)、SWH和能流密度的变化趋势、资源的总储量和有效储量等方面,对中国海域域的波浪能资源进行评估。研究发现:(1)南海北部四季皆为能流密度的大值区,各个季节基本都在8 kW/m以上,秋冬两季更是高达20 kW/m以上。(2)东海和南海大部分海域的波浪能资源开发有效时间出现频率较高。(3)能流密度的稳定性在1月最好,4月和10月次之,7月最差;南海能流密度的稳定性好于其余海域,其中又以南海北部海域的稳定性最好。(4)中国海域域大部分海域单位面积的波浪能总储量在2×10⁴ kW·h/m以上,高值中心分布于南海北部海域,有效储量的分布特征与总储量基本一致。(5)我国大部分海域的SWH和波浪能流密度呈显著的逐年线性递增趋势,SWH的递增趋势为0.5~2.5 cm/a,能流密度的递增趋势为0.05~0.55 kW/(m·a)。(6)我国大部分海域蕴藏着较为丰富的波浪能资源,其中南海北部、台湾以东洋面及琉球群岛附近海域为波浪能资源的优势区域。

Abstract: In this study, the third-generation wave model WAVEWATCH -Ⅲ (WW3) was used to simulate the wave field of the China Sea from January 1988 to December 2010, with wind input of CCMP wind field.In order to evaluate the wave energy resources reasonably, significant interval was defined.Synthetically considering the size of energy density, significant interval, stability and long-term trend of wave energy density, wave energy storage, wave energy in the China Sea were analyzed.Results show that, (1) Large area of wave energy density mainly located in the north waters of South China Sea, of above 8 kW/m all year round.(2) Frequency of significant interval in East China Sea and South China Sea is high.(3) Stability of wave energy density in January is better than that in April and October, and in July is the worst.Stability in north waters of South China Sea is much better than that in other areas.(4) Wave energy storage in most of China Sea is large than 2×10⁴kW·h/m, and the large area locates in the north waters of South China Sea.(5) SWH and wave energy density in most of China Sea have significant increasing trend from 1988 to 2010, of 0.5-2.5 cm/a in SWH and 0.05-0.55 kW/(m·a) in wave energy density.(6) There is a rich storage of wave energy in the China sea, especially in the north waters of South China Sea, Ryukyu Islands waters and east area of Taiwan Island.
