Wave breaking is an important process that controls turbulence properties and fluxes of heat and mass in the upper oceanic layer.A model is described for energy dissipation per unit area at the ocean surface attributed to wind-generated breaking waves,in terms of ratio of energy dissipation to energy input,windgenerated wave spectrum,and wave growth rate.Also advanced is a vertical distribution model of turbulent kinetic energy,based on an exponential distribution method.The result shows that energy dissipation rate depends heavily on wind speed and sea state.Our results agree well with predictions of previous works.
LADCP(Lowered Acoustic Doppler Current Profiler)的底跟踪速度为获取全水深绝对流速剖面提供了多个参考流速。然而,不同底跟踪参考流速得到的绝对流速剖面结果却不相同。针对该问题进行了分析,结果表明:底跟踪观测的样本数及其在总流速观测样本中的比例随着离底高度的增加而减小;由于观测误差存在,底跟踪观测样本得到的流速剪切和所有流速观测样本得到的流速剪切并不相等,从而导致不同底跟踪参考流速得到的绝对流速结果不同。
