The Current Status Of El Niño And IOD Signal And Their Impact To The Prediction Of Rainfall Variability Over Java Island (original) (raw)

Abstract

As one of the most important region located along the belt equator, the meteorological surface parameter over the Indonesia Maritime Continent (IMC) suspected effecting by the Monsoon system. This is caused IMC is located between two great continent (Asia and Australia) and two great ocean (Indian and Pacific). It indicates that the Sea Surface Temperature (SST) should become one of the most important parameter. Although, this region is effected by the Monsoon system, but another phenomena, called as the Indian Ocean Dipole (IOD) and El Nino suspected has a great effects also in determining the rainfall anomalies. By this reason, we investigated the IOD and El-Nino index, especially the SST Nino 3.4 index. By assuming the drought and wet extreme condition was mostly affected by both parameter, we analyzed the IOD and SST Nino 3.4 index for period of 1976 to 2000. For study case, we concentrated to analyse the monthly rainfall data over Java Island, especially when the strongest El N...
