| Abstract: | The Impact of the Indian Ocean Dipole (IOD) and the El Niño Southern Oscillation (ENSO) event for Indonesian rainfall has been investigated for the period from 1950 to 2011. Inter-annual change of IOD and ENSO indices are used to investigate their relationship with Indonesian rainfall. By using the wavelet transform method, we found a positive significant correlation between IOD and Indonesian rainfall on the time scale of nearly 2.5-4 years. Furthermore, the positive significant correlation between ENSO (sea surface temperature anomaly at Niño3.4 area indices) and Indonesian rainfall exists for shorter than 2 years and between 5.5 to 6.5-year time scales. |
