Indian Ocean Dipole


The Indian Ocean Dipole is a climate phenomenon that affects global climate. It is an irregular oscillation with positive and negative phases. In the positive phase, sea surface temperatures of the eastern Indian Ocean experience unusual cooling. This is soon followed by a warming of sea surface temperatures in the western Indian Ocean. These changes lead to a large shift in rainfall from the eastern towards the western Indian Ocean, and is consequently associated with drought in the eastern and floods in the western Indian Ocean.  

We study the mechanisms by which the Indian Ocean Dipole is generated using computer models. Areas of research include Indian Ocean Dipole dynamics, its impacts on global climate and how it interacts with the El Nino Southern Oscillation.
