| 摘 要： | 本文考虑的地形为理想的南北向长谷。建立了地形坐标下的二维非静力模式，详细研究了谷地中的风速和风向随盛行气流和谷轴的交角β、谷地的宽度、谷地的深度、谷地的相对深度以及温度层结的变化规律。模式计算的结果与三峡实际观测的统计结果相当一致。

| Abstract: | or infinite long North-South valleys. the present thesis has developted a two-dimensional nonhydrostatic model, which includes topography. It has leen studied in detail how the wind speeds and directions in the valley depend on the cross-angle between the airflow directions and the valley axis, the valley width, the valley deep, the valley relative deep and the temperature stratification. The simulated results agree quite well with the real observed statistical results made at Sanxia Valley. |
