Aneesh Subramanian

Dr. Aneesh Subramanian is an Assistant Professor in the Department of Atmospheric and Oceanic Sciences (ATOC) at the University of Colorado Boulder. He also holds visiting positions at the Center for Western Weather and Water Extremes at Scripps Institution of Oceanography, UC San Diego, and as a visiting scholar in the Predictability of Weather and Climate group at the University of Oxford. Additionally, he serves as an international collaborator with the Geophysical Flows Lab at the Indian Institute of Technology Madras.

His educational background includes:

• Ph.D. in Climate Research from Scripps Institution of Oceanography, UC San Diego (2012)
• M.Sc. (Engineering) from Indian Institute of Science (2006)
• B.Tech from Indian Institute of Technology (IIT) Madras (2004)

Dr. Subramanian's research focuses on weather and climate predictability, with particular emphasis on subseasonal-to-seasonal forecasting. His work spans tropical climate dynamics, atmospheric river prediction, data assimilation techniques, and the application of machine learning to improve earth system models. He investigates coupled ocean-atmosphere processes, particularly related to the Madden-Julian Oscillation and its teleconnections, and develops stochastic parameterization schemes for climate models.

Dr. Subramanian's recent publications demonstrate a strong focus on advancing subseasonal-to-seasonal prediction capabilities, particularly for extreme weather events like atmospheric rivers and marine heatwaves. His work increasingly integrates machine learning techniques with traditional physics-based approaches, reflecting a growing trend in the field toward hybrid modeling frameworks. Much of his recent research examines regional climate phenomena in the Indian Ocean, Pacific, and Arabian Sea regions, with applications to monsoon prediction and understanding climate change impacts.

Dr. Subramanian has received several notable awards and honors throughout his career:

• Best Team in visualization of weather forecasts Award, ECMWF Users Meeting (2017)
• Best Student Presentation Award, WCRP Open Science Conference (2011)
• Best Teaching Assistant Award, Scripps Institution of Oceanography (2011)
• SUNNY Scripps-NCAR Graduate Student Fellowship (2009-2011)
• NCAR ASP Summer Fellowship (2008, 2012)

Dr. Subramanian has secured multiple research grants totaling over $3 million from agencies including NOAA, ONR, NASA, and KAUST. Current projects focus on improving understanding of air-sea interaction processes, marine ecosystem drivers in the California Current System, monsoon intra-seasonal oscillations, and marine heatwaves. He actively mentors undergraduate research assistants, graduate students, and postdoctoral scholars through his Climate Processes and Predictability Group at CU Boulder.

Dr. Subramanian leads the Climate Processes and Predictability Group at CU Boulder, which focuses on subseasonal predictability, data assimilation, Atmospheric River dynamics, and tropical-extratropical teleconnections. He is also an active participant in several collaborative research initiatives including the Geophysical Flows Lab at IIT Madras and the Center for Western Weather and Water Extremes at Scripps Institution of Oceanography. His work frequently involves international collaborations with researchers from institutions in the UK, Saudi Arabia, and India.
