Abstract: Beside the latitude, height and distance from sea, the local climate in mountain area is affected by the relief factors such as the slope grade and orientation of the sloping terrain, geographic conditions and shaded grade of terrain,etc. Applying the small net method, this paper developed corrected climatological equations, in which the relief factors were introduced. These equations can be used to calculate the quantities of meteorological elements such as temperature and precipitation at each point on the map which netted per 1 km. The results of the calculation are useful for utilizing and developing the localclimate resources in the mountain area.
