Abstract
Aim of this research is to study periodic modeling of daily rainfall time series. The study was undertaken using 25 years (1977–2001) data of Purajaya region. The series of the daily rainfall data assumed was trend free. The stochastic component of the daily rainfall was neglected. The periodic component of daily rainfall time series could be represented by using 253 harmonic expressions. Validation of generated daily rainfall series was done by comparing synthetic or generated with measured daily rainfall series. Mean of the correlation coefficient between generated and measured daily rainfall series with the number of the data N is equal to 512 days for 25 years was found to be 0,9576. Therefore, the developed model could be used for future prediction of daily rainfall time series.
