The IOD involves an aperiodic oscillation of sea-surface temperatures (SST), between "positive", "neutral" and "negative" phases. A positive phase sees greater-than-average sea-surface temperatures and greater precipitation in the western Indian Ocean region, [dubious – discuss] with a corresponding cooling of waters in the eastern Indian Ocean—which tends to cause droughts in adjacent ...
Positive phase of Subtropical Indian Ocean Dipole is characterized by warmer-than-normal sea surface temperature in the southwestern part, south of Madagascar, and colder-than-normal sea surface temperature off Australia, causing above-normal precipitation in many regions over south and central Africa.
IOD develops in the equatorial region of the Indian Ocean from April to May and peaks in October. [28] With a positive IOD, winds over the Indian Ocean blow from east to west. This makes the Arabian Sea (the western Indian Ocean near the African coast) much warmer and the eastern Indian Ocean around Indonesia colder and drier. [28]
The 2024–25 South-West Indian Ocean cyclone season is the current annual cycle of tropical cyclone and subtropical cyclone formation in the South-West Indian Ocean. It began on 15 November 2024, and will end on 30 April 2025, with the exception for Mauritius and the Seychelles , for which it will end on 15 May 2025.
The Indian Ocean gyre is composed of two major currents: the South Equatorial Current, and the West Australian Current. Normally moving counter-clockwise, in the winter the Indian Ocean gyre reverses direction due to the seasonal winds of the South Asian Monsoon. In the summer, the land is warmer than the ocean, so surface winds blow from the ...

Since Indian Ocean water is significantly warmer (24-26 °C) and saltier than South Atlantic water, the Agulhas Leakage is a significant source of salt and heat for the South Atlantic Gyre. This heat flux is believed to contribute to the high rate of evaporation in the South Atlantic, a key mechanism in the Meridional Overturning Circulation.
