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.CAOS offers a vibrant and supportive environment for graduate study. Students can pursue graduate degrees (MTech and PhD; see Programs for details), and are trained to think across disciplines, ask fundamental questions, and tackle real-world weather and climate problems.
Research over the past few decades, including work at CAOS, has shown that climate systems are deeply interconnected. For example, the Indian monsoon is not just a regional phenomenon—it is influenced by processes occurring across the globe and across a wide range of time and space scales. At the same time, it is changing in response to a warming climate.
Looking ahead, CAOS aims to better understand tropical climate and its global connections. By bringing together insights from different approaches, the centre seeks to build a more complete picture of how local processes and global influences interact—helping us better understand climate variability, extremes, and long-term changes.
We offer a variety of courses ranging from the basics of climate science to advanced fluid dynamics. The full list of courses offered throughout the year can be found here. Aspiring students are expected to know the basics of mathematics, physics, climate science, and other relevant subjects.
Once students are admitted, they usually go through the basic courses during the first semester. This provides them with a complete understanding of the subject and helps them decide upon the research they want to pursue in the department. Students are, of course, always welcome to discuss their ideas with faculty and seniors.
Ph.D & MTech(Research) in Atmospheric, Oceanic and Climate Sciences
