本文介绍了使用卫星高度计测量结果作为边界数据来驱动近岸频谱波模型 SWAN 的技术的开发和应用。目的是评估极端事件或近海气候变化对沿海地区的影响，并将卫星测高的用途扩展到更远的近海地区。为了验证该技术，选择了三个可以获得测深数据和一些现场数据的测试区域。该技术有可能适用于任何有测深信息的沿海地区，尽管如本文报告的结果所示，必须利用情报来调整不同地点的方法。还需要通过模型或测量获得有关当地风场的信息。三个试验区的实验表明，某一特定区域的近海波高气候与近海气候之间并不存在简单的关系。重要并发症...
This paper describes the development and application of a technique for using satellite altimeter measurements as boundary data to drive the nearshore spectral wave model, SWAN. The aim was to assess the impact in coastal areas of extreme events or changes in offshore climatology and to extend the usefulness of satellite altimetry further inshore. For the purpose of verifying the technique, three test areas where both bathymetry and some in situ data were available were chosen. The technique could, potentially, be applied to any coastal location where there is bathymetric information although, as the results reported in this paper show, intelligence must be used in adapting the methodology for different sites. It is also necessary to have information on the local wind field from either models or measurements. The experiments at the three test areas demonstrated that there is not a simple relationship between the offshore wave height climate and the inshore climate in a particular region. Important complic...
