Karakteristik Penyimpangan Curah Hujan Saat Kejadian Enso (El Nino Southern Oscillation) Di Indonesia Berbasis Satelit TRMM

Abstract

Indonesia where was located on the west of Pacific Ocean, has a climate strongly influenced by oscillations that occur in the ocean. This research was conducted, to obtain spatial results, which can explain the correlation between rainfalls in Indonesia with the southern oscillation phenomenon. With spatial method, it will get anywhere regions which significantly affect the incident in Indonesia. This is important, because many previous studies still use the station or in the form of point data, so the analysis only focused on the temporal side in some areas of observation only. Analysis of spatial correlation in Indonesia for both these parameters, are still rarely found. Calculation and analysis results obtained is a map of rainfall deviation during the Southern Oscillation Index (SOI) extremes and the map correlation coefficient between rainfall in Indonesia and the SOI, with values between -0.2 to 0.5, with a fairly high correlation found in the north Sulawesi island. Correlation analysis was also performed between rainfall in every season (3 months) with the SOI, which can be generated correlation value, both in DJF (December, January, February), MAM (March, April, May), JJA (June, July , August) and SON (September, October, November). The resulting correlation values ranging from -0.5 to 0.7.Hal. 235-24
