Influence of Indian Ocean Dipole Phenomena Towards the Eddy Variability in Southern Java Ocean

Title variants
Languages of publication
The phenomenon of Indian Ocean Dipole (IOD) can influence the variability of eddy in the Southern Java Ocean (SJO). The purpose of this research is to know the characteristics of eddy in the SJO at the time of the IOD condition. The research was conducted in Eastern Indian Ocean (EIO), South of the Java Island by coordinate 0º S – 15º S and 90º E – 120º E. The data used in this research is currents data, sea surface height (SSH) data, and temperature data from HYCOM, and Dipole Mode Index (DMI) data from Japan Marine Science and Technology (JAMSTEC). Methods used for detecting eddy is using the Automated Eddy Detection (AED) method. The results of this research show that the IOD phenomena affect the variability of eddies in the SJO, this is evidenced by the difference of the total eddies is generated at the time of normal conditions and at the time was going to the phenomenon of IOD. Total average eddies on IODM (+) conditions is 153 and on IODM (-) conditions is 144. IODM (+) conditions could cause the value of a central point of sea surface height (SSH) and sea temperature is lower than the normal conditions, the opposite IODM (-) conditions can cause the value of a central point of SSH and sea temperature is higher than the normal conditions.
