Study of Indonesia Rainfall Variations in Association with ENSO (Erwin Mulyana ) 発表要旨 :
ENSO event correlate with decreasing the rainfall in Jawa. The Jawa rainfall type is annual cycle with maximum rainfall is during winter and minimum rainfall during summer in the Northern Hemisphere. Jawa Rainfall index, wind flow and sea surface temperature have been examined to improve our understanding of precipitation in Jawa. The highest correlation between SOI and Jawa Rainfall is in September-November. In this season, when ENSO occure, the sea surface temperature in Indonesia water northern Australia is cold, causes strong easterly wind over Jawa. The decrease sea surface temperature and intensified easterly wind resulted in the decreasing Jawa rainfall. In December-February and March-May season, correlation between ENSO and Rainfall in Jawa is not significant. In June-August, correlation starting appear but not strongger than in September-November season.
