Antarctic Sea ice decline makes key ocean water mass saltier, raises warming concerns – Kaushik Mishra & Prof. Bishakhdatta Gayen

Abstract

Video

 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.

Graduate study at CAOS

CAOS offers a supportive environment for graduate study. Students can pursue MTech and PhD degrees, and are trained to think across disciplines, ask fundamental questions, and tackle real-world weather and climate problems.

We offer courses ranging from the basics of climate science to advanced fluid dynamics. The full list is on the courses page.
