Researcher Spotlight - Meet Bharath Krishnan, PhD Student Decoding the Atmosphere

Since May 2025, he has been part of TRR 181’s subproject W6: Spectral Energy Fluxes by Wave-Wave Interactions, under the supervision of Prof. Dr. Claudia Stephan and Dr. Yanmichel Morfa Avalos. In this interview, Bharath discusses his research focus on energy transfers in the atmosphere, his motivation driven by the complexity of atmospheric processes, and the vital role of interdisciplinary collaboration in understanding and predicting climate dynamics.

What motivates you to work in this field?

“I believe the atmosphere is one of the most complex, dynamic systems humans have ever studied. There is something fascinating about building upon simple physical concepts until they match real world observations. Ultimately, I am inspired to be part of a community working to improve climate models and enhance our understanding of a system that affects all our daily lives.”

How has your background and career path shaped your approach to climate science?

“In my undergraduate years, I was mostly focused on core physics, but a few projects made me realize I am more interested in climate sciences. That led me to my Master’s thesis in atmospheric physics, where I studied energy transfers in the tropics. When I started here, I had to learn a lot about upper atmospheric dynamics, but having some experience with energy spectra made the transition a bit smoother.”

What are your primary research interests?

“My research focuses on the interactions between wave modes, turbulence, and background winds to understand energy propagation across atmospheric scales. To investigate these mechanisms, I use high resolution regional data and a diagnostic framework that combines spectral energy budgets with scale-dependent transfers in physical space. While traditional methods often rely on global spectral data, my work adapts these budgets for regional domains to bridge the gap between spectral and physical space. Ultimately, I aim to pinpoint the exact locations where these energy transfers take place.”

What do you believe are the most pressing challenges in climate science today, and how does your work contribute to addressing them?

“One of the biggest challenges is that even our best models lose accuracy in weather prediction after about two weeks due to the dynamic nature of the atmosphere. Accurate long-range predictions are essential for us to manage resources and prepare for extreme weather. My work addresses this by ‘zooming in’ on regional domains to investigate specific mechanisms that drive energy transfers. By better understanding the underlying physics, we can develop more accurate parameterizations that lead to simulations much closer to reality.”

How does collaboration across different institutions and disciplines enhance the impact of your research?

“For me, a collaborative project like TRR 181 is really valuable because it brings together people with different research backgrounds who look at the same problems from different angles. I’ve found that explaining my research to peers from different backgrounds is actually the best way to find gaps in my own thinking and refine my approach. Whether it's during our workshops or during retreats, these interactions give me a fresh perspective on the research questions themselves.”

What advice would you give to students or young researchers interested in pursuing a career in climate sciences?

“If you are genuinely interested in climate sciences, don't hesitate to take a leap of faith. It doesn’t matter if your background is in physics, chemistry, math, computing or even biology; there is a place for every discipline in this research. You will find that no matter your expertise, there is important and relevant work happening that can benefit from your specific skills.”
