海浪向海岸传播过程中，由于变浅效应会改变海面粗糙度和海底应力对水体的影响，波浪破碎产生的海洋飞沫会影响大气底边界层的稳定性，同样，波浪在海底掀起的泥沙悬浮物会影响海洋底边界层的稳定性，从而改变海面风应力和海底应力。在浅水情形，大气底边界层和海洋底边界层还会发生相互作用。本项目探讨浅水情形下海浪与大气底边界层和海洋底边界层之间的相互作用机制，研究波浪和海流对海底摩擦力和海面风应力的影响，提出浅水情形下海面和海底应力参数化方案，提高浅海海浪和风暴潮模式的预报精度，为我国的减灾和防灾工作提供理论依据和技术支撑。

During the propagation process of ocean waves to the coast, the shoaling effect will alter the action of the sea-surface roughness and sea-bottom stress to water motion. The sea sprays induced by wave breaking in atmospheric bottom boundary layer (ABBL) and suspended sediments induced by waves in oceanic bottom boundary layer (OBBL) will have significant impacts on their stabilities, respectively. Thus the wind stress and sea-bottom stress will be changed. Moreover, ABBL and OBBL will interact on each other in the case of shallow seas. This proposal will investigate the interactions of ocean waves with ABBL and OBBL, and analyze the effects of waves and currents on sea-bottom stress and wind stress. The parameterizations of wind stress and sea-bottom stress in case of shallow seas will be proposed. They will be used to improve the prediction accurate of wave and storm surge models. The results can be applied as theoretical basis and technical support in the disaster prevention and mitigation of our country.
