This review brings together a new understanding of the ocean-atmosphere system in the Indian Ocean since the last comprehensive review, describing the Indian Ocean circulation patterns, air-sea interactions and climate variability.
Using ocean model simulations, this study demonstrates that the unusual behaviour of Indian Ocean temperatures over the past 60 years was mainly due to wind conditions.
All data sources agree that positive IOD events are becoming stronger and occur more often and that the mean-state of the Indian Ocean is moving towards a more positive IOD-like state due to enhanced warming in the west compared to the east.
Caroline Ummenhofer (Wood Hole Oceanographic Institute). Changes in the width of the Indo-Pacific tropical rain belt from climate model simulations and palaeo proxy records. The Indo-Pacific tropical rain belt (TRB) marks the high-rainfall region in the tropics traversed by the seasonal migration of the intertropical convergence zone. In particular, changes in the position of the northward and southward edges of the TRB can have considerable impacts on natural and human systems across the Indo-Pacific warm pool and adjacent land areas.

A range of international workshops, a new citizen science app and some significant research has made the past four months a busy time for the Extreme Rainfall research program.
