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。
Both the Wilson method and the well-island method are well-known wave estimation methods in the moving wind region and are widely used in the estimation and forecast of typhoon waves. This paper points out that when using the above method to forecast the typhoon wave based on the wind and wave forecast formula adopted by the marine engineering community, the steep eigenvalue of the characteristic wave will be inconsistent with the typhoon wave steepness distribution of the typhoon, and the cause of this defect is pointed out.
