The Centre for Atmospheric and Oceanic Sciences (CAOS) began with a strong focus on the Indian monsoon and has grown into a centre that studies the full range of atmosphere, ocean, and climate science. Today, CAOS is among the few places in the world, especially in India, where these complex systems are explored using a combination of observations, experiments, computer models, data analysis, and theory.

Research over the past few decades, including work at CAOS, has shown that climate systems are deeply interconnected. The Indian monsoon is not just a regional phenomenon: it is influenced by processes across the globe and across a wide range of time and space scales, and it is changing in response to a warming climate.
