- A report by the Australian Bureau of Meteorology highlights that the Indian Ocean Dipole (IOD) index has exceeded the positive threshold.
- IOD refers to the shift in sea-surface temperatures from warm to cool in the Indian Ocean basin to the South of Sri Lanka.
- Warmer in the western side of the basin is referred to as a positive IOD event, while the reverse indicates a negative event.
- A positive IOD event has boosted the performance of India’s South-West monsoon.
- IOD index must remain above the threshold for a sustained period before it can declare a positive event.
