IOD FEARS

What will is a sea-based phenomenon within India’s neighbourhood, called the Indian Ocean Dipole (IOD).

The IOD results from the seesawing of temperatures in the Indian Ocean, and nearly mimics the El Nino-La Nina processes in the tropical Pacific.

Warming of the west of Indian Ocean sets up a positive phase of the IOD, which is beneficial to the Indian monsoon.

When it shifts to the east, it results in the negative IOD, which suppresses rainfall over mainland India.

The RIGC expects a negative IOD to emerge in the Indian Ocean in August-September.
