Abstract: In this paper the variability of the precipitation, for annual and twelve monthes, was calculated in China, the formular is V_r=σ_x/x?100 In addition, the deviation of variability was calculated according to the method suggested by V. Conrad. The data of the precipitation used in this paper were collected from about 160 stations for the period of 1951-1980. Maps of variabilities of precipitation and that of their deviations for annual, January and July were presented respectively. The seasonal variations for the monthly variability of precipitation along both the latitudinal direction and the longitudinal direction were also discussed. It is found that the variability of precipitation in China converts from its summer pattern to winter pattern for both the latitudianal direction and the longitudinal direction in November. But the conversion from winter pattern to summer pattern for longituginal direction occurs in May and for latitudinal direction occurs in June.
