New Faculty: Dr. Sandeep Sukumaran

Dr Sandeep Sukumaran, Centre for Atmospheric Science

Sandeep grew up in Pathanamthitta in Kerala and was all set to pursue his career in Physics. However, when he was in the final year of his B.Sc Physics, he got to know about a Masters course in Metrology in Cochin University. This was when he moved from Physics to Metrology.

“Moving from Physics to Meteorology was not difficult. Study of atmosphere uses the fundamental principles of Physics. I found this very interesting,” he says.

Sandeep went on to do his PhD from IIT Kharagpur and did extensive research on numerical modelling of tropical cyclones over Bay of Bengal and Arabian Sea. After his PhD he got interested in climate change and joined as a Research Associate in Indian Institute of Science, Bangalore

As a post-doctoral fellow in the University of Oslo, he worked on Pacific Walker circulation which is an important component of the global climate system. This was followed by a second post-doctoral in New York University, Abu Dhabi Campus where he researched on Indian summer monsoon. The study was published in a very high impact journal Proceedings of the National Academy of Sciences
(http://www.pnas.org/content/115/11/2681).

“Our study showed that both a high resolution atmospheric model and a statistical model predicts that the activity of the storms weakens and shifts poleward from ocean to land in a warmer environment. The associated changes in seasonal mean rainfall and precipitation extremes are expected to have serious implications for the hydrological cycle of South Asia,” he said.

Sandeep joined IIT Delhi in November 2017.

He is continuing his research on changes in monsoon in a warming climate and is using a very high resolution climate model to study the monsoon.
