地形高差对风速影响的探讨

Discussing into Influence of Topographic Height Difference on Wind Velocity

微地形对风速的影响是明显而复杂的。本文研究了风向与地形倾向间不同关系中风速沿高程变化的影响量 ,并探讨了其变化规律 ,得出较为满意的地形高差对风速影响量估算的方法。可供山、丘区工程设计风速计算中 ,对工程区与引用气象台 (站 )观测场地有较大地形高差时 ,实测高水位期最大风速资料改正值估算的参考。

The influence of micro topography on wind velocity is obvious and complicated. The influence of topographic elevation on the wind velocity under different combination condition of the wind direction and topographic dip is studied, and the equation estimating the influence is derived respectively in this paper.The equation mentioned above can be used for the correction of the wind velocity obtained in a meteorologic station when the wind velocity data are to be used in a design of a Proisect (esp.in a reservoir design) which is located in hilly or mountainous area but there is a great difference in elevation between the meteorologic station and the Proiect site.
