Abstract

Aim of this research is to study periodic modeling of 15 days cumulative 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 periodic component of 15 days cumulative rainfall time series could be represented by using 253 harmonic expressions. The stochastic component of the 15 days cumulative rainfall was using the 3 rd order autoregressive model. Validation of generated 15 days cumulative rainfall series was done by comparing between the generated with the measured rainfall series. The correlation coefficient between the generated or synthetic rainfall series with the measured rainfall series with the number of the data N is equal to 512 days for 25 years was found to be 0.99996. Therefore, developed model could be used for future prediction of 15 days cumulative rainfall time series .
