Curve and uphill path resistance are great, linear resistance is little, declivous path still has quicken force.

及上道阻力大,直阻力小,下道还有加速力。

Such results are gotten: (1) Due to the unique topography the wind of Beijing area during the day time is southern anabatic wind and in the night is northern katabatic wind in summer.

(1)京区域夏季界层风场受西特殊地形的影响,夜间低层大气流场常表现为南的下风,白天逐渐转为南往的上风。
