  Multi-scale AI Modeling of Small-scale Turbulence Above Ocean Waves

  Kianoosh Yousefi, Ph.D., Assistant Professor of Mechanical Engineering, UT Dallas

  Winds and waves constantly exchange mass, momentum, and energy, shaping everything from daily weather to long-term climate. A key part of this process is the small-scale turbulence that forms just above and below the ocean surface. Despite its importance, scientists still know relatively little about how these turbulent motions work, mainly because they are so difficult to observe and measure. MORE >

  Our work combines carefully controlled laboratory experiments with artificial intelligence (AI) tools to better understand these processes. Using a custom wind–wave tunnel, we created detailed measurements of airflow over surface waves. We then trained an AI model to recognize patterns in the turbulent flow and to link them with wave properties that can be measured more easily. This approach allows us to reconstruct the small-scale turbulence that drives air–sea exchanges. By capturing this missing piece, our work opens a pathway to more accurate forecasts of weather and climate, while also helping us understand how the ocean and atmosphere interact at their boundary.
