在强烈的风暴下所产生的涌浪,因其微弱的耗散性,往往能够横穿整个洋盆.这一特性使得利用卫星遥感技术观测涌浪的产生、消亡过程,以及通过涌浪参数反演风暴特征成为了可能.本文利用2003~2010年Globwave提供的SAR波模式数据,根据涌浪的频散关系和其传播的几何光学定理对涌浪进行了反向的起源追踪,从而对产生涌浪系统的风暴进行了定位,并实现了对涌浪场的一致化时空场重构.通过与海面风速数据的对比分析,印证了这一方法的有效性.采用这一方法,本文得到了涌浪源起源的时空分布特征和相应的涌浪演化的一般过程.这些结果对涌浪预警、海浪模式、海气界面传输及气候变化等相关领域均有一定的应用价值.
The surging waves generated under intense storms often traverse the entire ocean basin because of their weak dissipation, which makes it possible to observe the occurrence and disappearance of surges using satellite remote sensing and to determine the effects of surges Storms characteristics have become possible.This paper uses the SAR wave mode data provided by Globwave from 2003 to 2010 to trace the origin of the surges according to the dispersion relation and the geometrical optics theorem of the wave propagation, The storm of the wave system is located and the uniform space-time field reconstruction of the surge field is realized. The comparison with the sea surface wind speed data proves the effectiveness of this method. Using this method, The temporal and spatial distribution of the origin of the wave source and the corresponding general process of the surge evolution.These results have certain application value in the fields of wave warning, ocean wave mode, air-sea interface transmission and climate change.
