利用海浪浮标资料和长达44年(1958-2001年)的后播资料，研究了比斯开湾东南部海域的波能资源。在总共13个研究地点中，有三个对应于波浪浮标(两个沿海浮标，一个在深水)，其余的对应于后播数据点。首先对资源进行了量化，除沿海浮标外，所有站点的年波能均超过200 MWh m(-1)，平均波功率在25kW m(-1)左右。这一可观的资源是比斯开湾位于大西洋东端的位置以及中纬度(盛行的西风带)的风向的结果。其次，根据海洋状态参数对资源进行了表征。年波浪能量主要由有效波高1.5~4.0m、能量周期10.5~13.5m、平均深水向NW-WNW的波浪提供。最后，波浪与不规则的水深测量相互作用，在某些近岸区域引起显著的波浪能量集中。这些热点具有最高的潜在波浪场址潜力；它们的位置是通过数值模拟确定的。(C)2010爱思唯尔有限公司。保留所有权利。
The wave energy resource of the SE Bay of Biscay is investigated using wave buoy data and a hindcast data set covering a 44-year period (1958-2001). Of the total 13 study sites, three correspond to wave buoys (two coastal, one in deep-water) and the rest to hindcast data points. First, the resource is quantified annual wave energy is found to exceed 200 MWh m(-1) at all the sites (with the exception of the coastal buoys), and average wave power is in the region of 25 kW m(-1). This substantial resource is the result of the Bay of Biscay's position at the eastern end of the Atlantic Ocean together with the wind regime of the mid-latitudes (prevailing westerlies). Second, the resource is characterised in terms of sea state parameters. The bulk of the annual wave energy is provided by waves with significant wave heights of 1.5-4.0 m, energy periods of 10.5-13.5 s, and mean deep-water direction NW-WNW. Finally, wave interaction with the irregular bathymetry gives rise, in certain nearshore areas, to significant concentrations of wave energy. These hot spots have the highest potential as prospective wave farm sites; their locations are determined using numerical modelling. (C) 2010 Elsevier Ltd. All rights reserved.
