本文分析了葡萄牙近岸波浪能空间分布的一些相关规律。根据1994-2003年10年期间的浮标测量数据，首先对目标区域的波浪气候进行了中期分析。利用基于WAM和SWAN两种最先进的频谱模型的波浪预测系统对波浪条件进行了评估。为了设计更好的模型配置，对该系统进行了验证测试。本文特别关注了被认为是深水波浪模拟中的薄弱环节的白浪过程。分析了高波和平均波条件下波浪能量在三种不同计算域中的空间分布。波浪能评估考虑了四个案例研究。第一个对应于一个共同的能量峰值，而其他三个对应于平均能量条件的不同模式。通过这种方式，从能量的角度来看，已经确定了一些具有更大潜力的领域。
Some relevant patterns for the wave energy spatial distribution in the Portuguese nearshore are analyzed in this work. A medium term analysis of the wave climate in the target area was first carried out based on recent buoy measurements covering the 10-year period 1994–2003. A wave prediction system based on the two state-of-the-art spectral models, WAM and SWAN, was used to evaluate the wave conditions. In order to design better model configurations, validation tests with this system are performed. Special attention is paid to the whitecapping process which is considered the weak link in deep water wave modelling. The spatial distributions of the wave energy were analysed in three different computational domains for both high and average wave conditions. Four case studies were considered for the wave energy assessments. The first corresponds to a common energetic peak, whereas the other three to different patterns of average energetic conditions. In this way some areas with greater potential from the energetic point of view have been identified.
