A simple linear regression describing relationship between standard deviation and the average (mean) annual precipitation in India has been estimated using data of uniformly spread 460 stations, each having homogeneous records for a long period 1901-1960. Assuming that annual precipitation at individual station in India is normally distributed and using relationship between S.D. and the average annual precipitation a diagram has been prepared, designated as average probability diagram (APD), which depicts probability distribution of annual precipitation over the country .Precipitation zones have been delineated in the country based on spatial variation of probability of getting specified amount of precipitation in different parts of the country .
