抽象的。大气和海洋中的内波经常是由平均流与底部障碍物(如山脉和海底海脊)相互作用而产生的。对这些环境现象的分析涉及到重力作用下非均质流体的理论模型。本文在地形幅度较小的假设下，考虑了山体分层流的半解析模型。人们的注意力集中在崎岖地形上方的驻波图案上。为了适应这种地形，模型方程包含了在不平坦的地面上确定的精确地形条件。计算并分析了具有有限峰数的正弦地形的波解。
Abstract. Internal waves in the atmosphere and ocean are generated frequently from the interaction of mean flow with bottom obstacles such as mountains and submarine ridges. Analysis of these environmental phenomena involves theoretical models of non-homogeneous fluid affected by the gravity. In this paper, a semi-analytical model of stratified flow over the mountain range is considered under the assumption of small amplitude of the topography. Attention is focused on stationary wave patterns forced above the rough terrain. Adapted to account for such terrain, model equations involves exact topographic condition settled on the uneven ground surface. Wave solutions corresponding to sinusoidal topography with a finite number of peaks are calculated and examined.
