Model 2 on the other hand generates a value of 743mm if the station point option is used and 862mm if the grid point option is used. If no, or not enough, observed rainfall is available then one cannot use stochastic rainfall to in-fill missing rainfall. Single day, month or years of stochastic rainfall cannot be used where observed daily rainfall are missing. The stochastic rainfall generator does not generate daily rainfall amounts in the same sequence that they occur in nature. The statistics are fairly well preserved when the complete record is compared to the observed record, but not when individual events are considered.
