| Summary: | This research is conducted to study the characteristics and variability of Mindanao
and Halmahera Eddies at seasonal and interannual time scales under normal, El
Niño, and La Niña conditions. A three-D baroclinic hydrodinamics model used in
this research is COHERENS (A Coupled Hydrodynamical-Ecological Model for
Regional and Shelf Seas) which was developed by Luyten, et al., (1999).
Bathimetry, water temperature, salinity, wind, air temperature, rain fall,
evaporation, cloud cover, and air pressure are used as input data. The results show
that the variability of Mindanao Eddy and Halmahera Eddy is influenced by
seasonal wind, El Niño and La Niña conditions. Under normal condition, during
west monsoon the center of Halmahera Eddy is located farthest south around 6,3º
N and 128,5º E, during first transition season it moves northward around 7º N and
128,5º E, during east monsoon it moves further northward around 7,7º N and
128,5º E, and during second transition monsoon it moves again southward around
7º N and 128,5º E. In general, the diameter and velocity of the Mindanao and
Halmahera Eddies are smaller during El Niño, and greater during La Niña than
normal condition. |
