Determination of the start <br /> <br /> <br /> <br /> <br /> of the season performed with ARIMA method. With ARIMA method, rainfall can be predicted with a good but not the value of above normal rainfall. Study of rainfal <br /> <br /> <br /> <br /> <br /> patterns and climatic classification done for the analysis of rainfall anomalies that occurred during the 16 years. South Tapanuli region has a rainfall patterns and the <br /> <br /> <br /> <br /> <br /> equatorial climate is very wet, then the controlling factor of precipitation is ITCZ.
