CoE in Climate Modelling

Researchers at IIT Delhi are working towards developing a climate model that caters to the specific needs and challenges of climate change in India.

The Center

DST Centre of Excellence in Climate Modeling is a major new initiative taken by IIT Delhi and funded by the Department of Science and Technology, GoI to develop an India centric climate model to address certain pressing issues of climate change in India, and to educate manpower in numerical modeling of the Earth system and climate.

The need

The country needs reliable climate projection for future planning and policy making to make in-formed decisions against the backdrop of global warming and climate change. This is deliverable only when we have a reliable model - a model which is successful in capturing the present-day cli-mate of India. If we do not have a model that captures the present-day climate, how can we expect to predict and project for the future? Reliable future projections of climate demand a satisfactory numerical global model. However, all the available models possess unacceptably large biases, espe-cially with precipitation over India (see the figure), even though they are doing reasonably good jobs over other regions and at global scale. Although the climate modeling community in the coun-try has made good progress in the last two decades, the need of the hour is to accelerate this process and work towards building a model for India that can be used for regional climate projections.

Broader objectives

The researchers propose to perform the required upgrades to an existing climate model and build a better model for the Indian region through improved physical and computational implementations. They aim to develop an India-Centric Climate Model (ICCM) through process improvements and region-specific customisation that can simulate the regional climate of India and can be used for fu-ture climate projections at district level to assess the impacts of climate change on agriculture, health, water resources, and the energy sectors. The ICCM output will be downscaled at ultra-high resolutions for various applications. Additional climate projections for the future scenarios will be made through soft computing, machine learning, and mathematical optimisation techniques from the ICCM.

Prospect and Opportunities

The subject matter is highly interdisciplinary and involves integration of atmospheric physics and dynamics, numerical methods, thermodynamics, heat transfer, high performance computing, and soft computing. Faculty members having expertise in these area may find it exciting and are wel-come to participate as associate faculty members in the CoE.
