Abstract

Strong negative Indian Ocean Dipole (IOD) event took place in the tropical Indian Ocean during 2016. Based on the Dipole Mode Index (DMI), the event has shown two peaks: in July and September. It is shown that the second peak was stronger than the first peak. Evolution of the event has started in May, reached its first peak in July, weaken in August, but rebounded and came to its second peak in September. The event was terminated in November. Robust sea surface temperature (SST) dipole patterns were observed during both peaks. In July, the SST anomaly in the eastern (western) pole of the IOD reached +1C (-1.5C). Meanwhile, during the second peak of the event, the SST anomaly in the eastern (western) pole of the IOD rose (fall) to nearly +2.5C (-1C). As a consequence, strong convective activities were observed over the maritime continent causing heavy rainfall during the peak of the event. On the other hand, there was a significant reduce of the rainfall over the eastern Africa during the peak of the event.
