本文对线性分层流中表面障碍物后产生的背风波展向结构进行了实验研究。注意力主要集中在两个方面：第一，背风面波浪破碎总是发生的条件;第二，波浪振幅在跨度上衰减的速率。虽然只使用了一种特殊的机身形状--一种在所有情况下都能促进附面层分离的形状--但有人认为，结果的形式应该是普遍适用的。数据进行比较，在可能的情况下与线性理论的影响，一个圆形的山或一个长的山脊。
An experimental study of the spanwise structure of lee waves generated behind a surface mounted obstacle in linearly stratified flow is described. Attention is concentrated, first, on the conditions under which lee wave breaking always occurs and, second, on the rate at which the wave amplitudes decay across the span. Although only one particular body shape was used—one which promoted boundary layer separation in all cases—it is argued that the form of the results should be generally applicable. The data are compared where possible with the implications of linear theory for a circular hill or a long ridge.
