Sea surface roughness has a major influence on global climate modelling. This project will provide a better understanding of the variability of sea waves in coastal waters. New technology of HF ocean radar can map wave fields over coastal waters and thus fill a gap between the open ocean satellite measurements and the point measurements from wave buoys. In this project we will improve the analysis of the radar echoes to produce sea wave spectra, and evaluate focussing of waves by complex currents on the continental shelf to help improve wave forecasting in coastal waters. The HF radar will be used to experimentally test current theories of wind wave spreading.

海面粗糙度对全球气候模式有重大影响。这个项目将使人们更好地了解沿海水域海浪的变化。高频海洋雷达的新技术可以绘制近岸水域的波场，从而填补了开阔海域卫星测量与波浪浮标点测量之间的空白。在本项目中，我们将改进雷达回波分析以产生海浪光谱，并评估大陆架上复杂洋流对海浪的聚焦，以帮助改进沿海水域的海浪预报。高频雷达将用于实验验证当前的风波传播理论。
