摘要

The model for stochastic generation of 6 minute rainfalls generates daily rainfalls using a well tested model and then disaggregates the daily totals into 6 minute diurnal patterns. The disaggregation process uses a file of stored patterns taken from the nearest pluviometer record. The selection of a pattern for disaggregation depends on the month of the year and the amount of rainfall in the day. After initial disaggregation to 6 minute patterns, the generated data are adjusted to make the generated monthly and annual means, and standard deviations match those from the input data. Results are given for annual, monthly and daily means and standard deviations, and for sub-daily intensities compared with IFD data prepared by the Bureau of Meteorology. Nonlocal pluviometer data from up to 160 km from the study site gave good results, showing that the system can be used with daily rainfall data at the site of interest and pluviometer data from some distance away.
