The Banda Sea experiences a strong upwelling between April and November associated with the seasonal strengthening of the trade winds. Data of surface wind, sea surface temperature (SST) and salinity in the period of 1990-2008 were used to further study the response of upwelling to the local and remote forcing in the Banda Sea. A local forcing (Ekman Pumping) during Southeast Monsoon plays role in contributing the upwelling intensity indicated by shallower thermocline and colder SST. In addition, this study exhibits that the upwelling strength is controlled remotely by El Ñino Southern Oscillation (ENSO) where during El Niño (La Niña) periods in Southeast Monsoon, the upwelling weakens (strengthens) in the Banda Sea.
