TOHOKU模式是一种混合型的,因为它把风浪的单一参数增长方程与涌分量相结合,而且包括涌浪与风浪之间的互换。 19.1 单一参数风浪部分的背景 风浪部分最基本的特征是在成长的风浪中应用一个自相似结构,即由TOba(1972)提出的一个关于成长的风浪的无量纲波高与周期之间的简单的指数定律来表示。 H_s~*=BT_s~(*3/2) B=0.062 (19.1)式中H_s~*=gH_s/u_x~ 2 ,T_s~*=gT_s/u_*是有效波高H_s和有效周期T_s通过重力加速度g和大气的摩擦速度u_*标准化后的无量纲形式。这个指数定律是经过多组实验室和海上资料证明的(如Kawai等,1977;Mitsuyasu等,1980)。该定律不仅符合Wilson(1965)和Mut-suyasu等(1971)给出短风区的经验公式,如果除去无量纲风区的话,Wilson等1965年长风区的复杂公式,事实上也符合这个能量定律。图(19.1)给出了一组混合资料的比较情况,3/2次方的能量定律(19.1)可被转换为:
The TOHOKU model is a hybrid because it combines the single parameter growth equation of storm waves with the surge component and includes the swaps between surge and storms. 19.1 The basic feature of the background wind and wave part of the single parameter wind and wave part is to apply a self-similar structure in the growing wind and waves, namely, a simple index proposed by TOba (1972) about the dimensionless wave height and period of the growing wind wave The law says. H_s ~ * = BT_s ~ (* 3/2) B = 0.062 (19.1) where H_s ~ * = gH_s / u_x ~ 2 and T_s ~ * = gT_s / u_ * are the effective wave height H_s and the effective period T_s by the gravitational acceleration g And normalized frictionless velocity u_ * dimensionless form. The law of the index is demonstrated by multiple laboratory and maritime data (eg Kawai et al., 1977; Mitsuyasu et al., 1980). This law not only conforms to the empirical formula of the short-haul zone given by Wilson (1965) and Mut-suyasu et al. (1971), but also the complex formula of Wilson et al. law. Figure (19.1) shows a comparison of a set of mixed data. The law of energy (19.1) for the power of 3/2 can be converted to:
