According to New Scientist, scientists from the Australian research agency CSIRO studied how climate change will affect Indian Ocean's positive and negative oscillation by examining latest climate models.
In the positive phase, temperatures of the sea surface rise in the Arabian Sea and fall around Indonesia, and vice-e-versa in the negative phase.
Researchers concluded that difference between the two Indian Ocean regions concerned in the Indian Ocean Dipole will swell with positive events becoming more frequent.
The research warned that by 2100, these events will be at the mild end of the spectrum, but reducing planet-warming emissions soon may lessen the effect of such conditions.
One of the scientists, Wenju Cai, said that we will need to change our definitions to refer to the new normal conditions.
The study is published in the journal Nature Geoscience.
