Positive Indian Ocean Dipole emerging, but pattern may deviate

Original: Signs of a positive Indian Ocean Dipole, but it may not follow the textbook

Forecasters are reporting early signs that a positive Indian Ocean Dipole is developing in the tropical Indian Ocean. Such events typically bring above-average rainfall to parts of East Africa and drier conditions to Australia and Southeast Asia. However, meteorologists caution this event may not behave like a textbook case, so the usual regional climate impacts are less certain than normal.

Why now: The potential development of a positive IOD matters because of its wide-ranging effects on rainfall, agriculture and drought risk across countries bordering the Indian Ocean.
