摘要
The Impact of the Indian Ocean Dipole(IOD)and the El Nino 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 Nino3.4 area indices)and Indonesian rainfall exists for shorter than 2 years and between 5.5 to 6.5-year time scales.
