This paper concerns the development of a method for predicting ty- phoon waves on the basis of wilson's formulas. Wilson' equations are mo- dified, transformed into iterative forms, and then numerically solved us- ing a technique of optimization. A comparison of the predicted and mea- sured values shows good agreement between them. In establishing wind fields, not only the symmetrical wind field gen- erated by the gradient wind, but also the wind field produced by the motion of the typhoon centre is taken into consideration, resulting in a higher accuracy of prediction as compared to the wind field where only the gradient wind is incorporated. An optimal path of typhoon-wave propagation in the wind field of typhoon is obtained by the use of the dynamic programming theory, the- reby enabling the problem of typhoon-wave direction to be embodied in typhoon forecasts, which is very important for coastal engineering. This is of great practical value.

本文以Wilson公式为基础,并将其改造成递推形式,然后应用最优化技术,进行数值求解。计算结果经与实测资料比较,符合良好。在建立风场时,不但考虑了由梯度风引起的对称风场,而且还考虑了由台风中心移动所引起的风场。从而较单纯考虑梯度风的风场,提高了精度。在台风区内,采用动态规划,求取了一条最佳的台风浪传播途径。从而在台风浪预报中,体现了对海岸工程极为敏感的方向问题。具有明显的实用价值。

In this paper, an essential defect is described of Wilson's method in the calculation of typhoon wave. It is common knowledge that the equivalence of characteristic wave has to be applied repeatedly for calculating wind wave in the case of moving fetch. It is shown that for a kind of relationship, such as Wilson IV, Bretschneider and Rjeplinskii etc., the characteristic wave height and period increase with the fetch in the nondimensional form, but the characteristic wave steepness decreases with the nondimensional...

In this paper, an essential defect is described of Wilson's method in the calculation of typhoon wave. It is common knowledge that the equivalence of characteristic wave has to be applied repeatedly for calculating wind wave in the case of moving fetch. It is shown that for a kind of relationship, such as Wilson IV, Bretschneider and Rjeplinskii etc., the characteristic wave height and period increase with the fetch in the nondimensional form, but the characteristic wave steepness decreases with the nondimensional fetch. In this case, the equivalence will make the wave steepness lower further when the wave moves from a fetch with lighter wind speed to another with stronger wind speed. Thus, the wave shape calculated by Wilson' s method will became flatter. Evidently, it is not agree with the fact that the more close to the typhoon centre the wave is, the larger the wave steepness is.

Wilson方法和井岛方法均是移动风区上著名的波浪推算方法,被广泛应用于台风波浪的推算和预报上。本文通过分析指出:使用上述方法以海洋工程界所推行的风浪预报公式作台风浪推算时,所得特征波波陡将与台风浪实测波陡分布定性不符,并指出产生这种缺陷的原因。

A hybrid wave numerical model and the WAM model are jointly usedto predict typhoon waves on the coastal sea of Zhujiang Delta. In the areaof North-West Pacific Ocean arid China Sea, the wave prediction is implemented by the hybrid wave numerical model with 1° × 1°grids, while in thearea of the coastal sea, by the WAM model with 0.25 °×0.25°'grids.In the latter refractions of waves caused by the topography of sea bottomare included. Boundary conditions on the open boundaries of the small areaare provided by the...

本文将混合数值海浪模式与第三代海浪模式结合起来研究近岸台风浪。在西北太平洋及中国海域采用混合数值海浪模式预报海浪,而在近岸台风区域采用包括海底绕射项的WAM模式,该小区域的浪边界条件由大区域上得到的计算结果提供。我们建立的数值近岸台风浪预报系统。既利用了混合海浪模式节省计算机时的优点,又用细网格的WAM模式抓住了近岸海底地形对海浪的作用.该模式的后报结果表明,模式计算的近岸台风浪与台站的实测资料符合较好,为我们进行近岸台风浪的准确数值预报提供了有力的手段。
