Our Research
Our research spans critical components of the Earth system, aiming to deepen scientific understanding of climate dynamics, cryosphere processes, atmospheric interactions, and oceanic biogeochemistry.
Earth System Model Development
The continuous development and coupling of key Earth system components within IITM-ESM, including the ocean, atmosphere, sea ice, land surface, ice sheets, and glaciers, to improve climate-scale simulations, with an emphasis on the Indian monsoon and its global teleconnections
High-Resolution Climate Modelling: Global and Regional Perspectives
We produce high-resolution climate simulations using the atmospheric component of the IITM Earth System Model (IITM-ESM) for global and regional applications and CORDEX-compliant regional climate models for South Asia.
Monsoon Systems, Teleconnections, and Climate Variability
We investigate the variability in the Indian Summer monsoon, its teleconnection patterns (ENSO, IOD, MJO), and its linkages with regional and global climate systems. Our work integrates reanalysis, climate modelling using IITM-ESM
Polar Sea Ice, Ice Sheet Dynamics, and Ocean Circulation
Our research explores the evolving dynamics of Arctic Sea ice and Antarctic ice sheets in response to global warming. Focus is given to the influence of polar meltwater on large-scale ocean circulation, including the Atlantic Meridional Overturning Circulation (AMOC), and the resulting climate teleconnections across hemispheres
Aerosols and Their Climatic Interactions
We study the role of natural and anthropogenic aerosols in modulating radiative forcing, cloud microphysics, and regional climate extremes. Emphasis is placed on understanding aerosol-monsoon interactions and their representation in Earth system models.
Himalayan Cryosphere and Climate Response
We study glacier retreat, snow cover variability across the Himalayan region using remote sensing, in situ observations, and glacier modelling. Our research focused on understanding cryosphere–climate interactions to provide long-term adaptation strategies in this climate-sensitive mountain system
Ocean Biogeochemistry and Carbon Cycling
Our group investigates oceanic nutrient dynamics, biological productivity, and carbon cycling processes under changing climate conditions and works towards improving their representation in Earth system models
Land Use and Land Cover Change (LULCC) and Climate Interactions
We examine the impacts of land use and land cover change on regional climate, hydrology, and ecosystem dynamics. We study the impacts of deforestation, urbanization, and agricultural shifts, and their feedbacks on the monsoon system, and surface energy balance using the IITM Earth System Model.
