| 摘 要： | 利用球坐标系中的二维潮波方程组,以T/P卫星沿迹分析结果为开边界条件的边值法,计算了黄海中的一个四边形区域.结果证明了此方法的可行性.同时在调试底摩擦系数时,发现其对本方法的影响甚小,说明本方法计算不同区域的潮汐数值模型时,底摩擦系数都可以取为0.0022,省去对底摩擦系数的调试过程.

| Abstract: | Under the spherical coordinate, the boundary value method using the along track estimates of T/P satellite as open boundary conditions is applied to establish tide models in the Yellow Sea. The results prove the applicability of the method. While testing bottom friction coefficient, the comparisons show that its effect is small. Thus, its value can be taken as 0.0022 without testing process. |
