ANALISIS HUBUNGAN INDEKS NINO 3.4 DENGAN CURAH HUJAN DI JAWA TENGAH
Keywords:
Correlation, El Nino, La Nina, Rainfall, Central JavaAbstract
The Niño 3.4 index is the most commonly used index to define the events of El Niño and La Niña. In general, it is known that El Nino reduces rainfall and La Nina increases rainfall in the Indonesian region but the intensity varies depending on location and local conditions. Especially in Central Java, it is necessary to know how far the relationship between the events of El Nino and La Nina with variations in rainfall can be identified as one of the factors to consider in conducting climate forecasts. By using the correlation test it can be seen that the positive relationship of rainfall with the Nino 3.4 index has a strong correlation level but not significantly in the strong El Nino category for the Kawunganten, Purwonegoro, Penusupan and Kandangserang regions. While a significant negative correlation between rainfall and the Nino 3.4 index has a strong correlation with the moderate La Nina category for the Trangkil, Cabean and Jakenan regions.
