Sequential Generation of Short Time-Interval Rainfall Data

Hourly and six-minute interval models were developed to stochastically generate sequences of rainfall depths. The models were applied to data recorded at twelve rainfall stations in Australia,including several from the arid zone. At each station, several replicates of rainfall sequences of length equal to the historical record were generated. Based on a range of parameters covering short rainfall bursts up to annual totals, the models were shown to be performing satisfactorily.
