摘要： 本文通过黄土高原平均气压场、风场、湿度场和降水的分布特征、季节变化以及相互关系的分析,发现中小尺度山系有其特定的气压系统和相应的盛行风场,并对降水有重要影响.文章对黄土高原气候做了一些成因上的解释.

Abstract: This paper analysed the atmospheric pressure, air temperature, humidity, wind field and rainfall in loess plateau, and the relationship between topography and climate has been discussed.The results obtained has showed that (1). the topography has a great influence upon atmospheric pressure field whether in winter or summer. Furthermore, the character of this influence and the direction of rife-wind are closely interconnected, (2) The rife-wind is suited to the pressure systems, and they have closely relation to rainfall, (3) The Baiyu Mountains is an important climateline.
