Abstract: This paper discusses by using two examples the calculating question of professor Fu Baopu's experimental formula for Mountain precipitation and points out that the improvement of the calculating method for this formula suggested by yan Yuhua and Lai Hongnian which was published on Geographical research 6(1) has a lot of questions. Between the calculating result of Fu's formula and the practical material of the two examples, there appear more differentiations.

Key words: Mountain precipitation, Distribution model
