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.
