采用常深度(h=20米)封闭海做为计算域,强迫力只考虑常北风(V=20米/秒)产生的风应力,用Fischer(1950)建立的有限差分格式求解二维全流方程组,计算获得了一些有益结论: 1.科氏力驱使风暴潮波沿封闭海按反时针方向传播。 2.所有增、减水波表现出假潮周期的振荡。 3.两种不同的底摩公式对增、减水波的影响是有差别的。 4.只考虑风应力,封闭海中的增、减水波表现出南北反相的强迫振荡。
The closed sea with a constant depth (h = 20 m) is used as the computational domain. The forcing force considers only the wind stress generated by a constant north wind (V = 20 m / s). The finite difference scheme established by Fischer Flow equations, the calculation obtained some useful conclusions: 1. Coriolis force to drive the storm tidal waves along the closed sea by counterclockwise direction. 2. All increasing and decreasing wave show the oscillation of the wave period. 3. Two different Timothy formula on the increase, reducing the impact of waves there is a difference. 4. Considering only wind stress, the increase and decrease waves in closed sea show forced oscillation with north-south reversed phase.
