摘要
根据海浪冬季波高大于夏季的波高的观测事实,利用Simth(1988)的外海观测资料,对数据进行多元数学回归,提出了海-气温差对对拖曳系数CD的订正公式,对动量传递过程给出合理的动力学分析,结果简单,物理意义清楚,便于使用。
Based on the observation fact that the wave height in winter is higher than that in summer,according to the observation data in the open sea by Simth （1988）,using the multi-dimensional mathematics method,we propose the revising formula of the coast air temperature difference to drag coefficient CD.Meanwhile,this paper makes a reasonable dynamics analysis to the momentum transmission process using the revising formula.Overall,the formula is advantageous for using.
