About the Editors
R. Krishnan specializes in climate modelling studies on scientific issues relating to the
“Dynamics, variability, and predictability of the Asian monsoon, climate change and its
impacts on monsoon precipitation, weather and climate extremes, phenomenon of monsoon
breaks and droughts”. Currently, he is leading the Centre for Climate Change Research
(CCCR) at the Indian Institute of Tropical Meteorology, Pune, and is involved in developing
in-house capability in Earth System Modeling to address various scientific issues related to
climate change and monsoon. He carried out Ph.D. research in Atmospheric Sciences at the
Physical Research Laboratory, Ahmedabad, and obtained Ph.D. degree from the University of
Pune in 1994. He has published more than 100 scientific articles/papers, advised Ph.D.s
(11 awarded, 12 ongoing) and Master (6 M.Sc/M.Tech) dissertations, and offered training
lectures in Geophysical Fluid Dynamics & Atmospheric Science. He is Fellow of the Indian
Academy of Sciences (IASc), Indian National Science Academy (INSA), and the Indian
Meteorological Society (IMS). He is a Member of the Joint Scientific Committee (JSC) of the
World Climate Research Programme (WCRP), Coordinating Lead Author (CLA) of the
Chapter on Water Cycle Changes in the IPCC WG1 Sixth Assessment Report (AR6), and
CLA of the Chapter on Climate Change in the Hindu Kush Himalayan (HKH) Monitoring and
Assessment Programme (HIMAP). He also served as a Member of the CLIVAR Monsoon
Panel and the CORDEX Science Advisory Team of the WCRP, WMO. He is an Editor for the
scientific journals—Earth System Dynamics (EGU Journal), Mausam (IMD Journal), and
Journal of Indian Society of Remote Sensing.
J. Sanjay specializes in the area of regional climate change with a focus on the generation of
future climate change scenarios for the Indian monsoon region using dynamical downscaling
techniques with high resolution regional climate models (RCMs). He is leading the CCCR
team for coordinating the data archiving, management, and dissemination activities of the
South Asia component of the international coordinated Regional Climate Downscaling
Experiment (CORDEX) initiative by the World Climate Research Program (WCRP) of WMO.
Prior to joining IITM in 1988, Sanjay completed M.Sc. in Meteorology at the Cochin
University of Science and Technology. He carried out Ph.D. research in Atmospheric Sciences
at IITM and obtained Ph.D. degree from the University of Pune in 2007. He has 40 publications, including 21 papers in peer-reviewed journals. Sanjay is a Member of the
WCRP CORDEX Science Advisory Team (SAT), a Contributing Author (CA) of the IPCC
Working Group I (WGI) Sixth Assessment Report Chapter Atlas, and a Lead Author
(LA) of the Chapter on Climate Change in the Hindu Kush Himalayan (HKH) Monitoring and
Assessment Programme (HIMAP). He was also a scientific knowledge partner on climate
science for a segment of the International CARIAA research programme on climate change
Adaptation at Scale in Semi-Arid Regions (ASSAR) of India.
Chellappan Gnanaseelan is a Senior Scientist and Project Director of Short Term Climate
Variability and Prediction, at the Indian Institute of Tropical Meteorology, Pune. He received his
Ph.D. and M.Tech. degrees from the Indian Institute of Technology (IIT), Kharagpur, India.
