Abstract: Many meteorological and oceanographic processes throughout the northwestern Atlantic such as storm tracks and shelf water transport is dominated by the positions and dynamics of the western boundary current (WBC, namely the Loop Current-Gulf Stream system). Due to the high nonlinearity associated with this WBC current system, predicting the meanders and frontal positions of the WBC has been a long-standing scientific challenge. Based on high-resolution ocean modeling and ensemble data assimilation, we have developed a 30-year ocean reanalysis (1993-2022) for the Northwest Atlantic Ocean. This new daily, 4-km resolution dataset allows us to subsequently develop a highly efficient deep-learning approach that can generate long-term predictions of the eddy shedding and meanders of the WBC over several months timescales. Model constructions, validations, and case studies of the mesoscale WBC dynamics and prediction will be discussed in this presentation.

Bio: Dr. He is a Goodnight Innovation Distinguished Professor in the Department of Marine, Earth, and Atmospheric Sciences at North Carolina State University. His research expertise spans from coastal circulation dynamics and air-sea interaction to biophysical interactions. As the director of the Ocean Observing and Modeling Group, he conducts coastal ocean observations, and remote sensing data analyses, and leads the development of prediction models of ocean circulation, air-sea-wave interactions, physical-biogeochemical couplings, as well as data assimilation.  Dr. He is an Editor for the AMS Journal of AI for the Earth Systems and served as an Associated Editor for the AGU Journal of Geophysical Research-Oceans. He also serves on the editorial boards of several other scientific journals and on the organizing committees of several major international science meetings. He was the co-chair of Gordon Research Conference on Coastal Ocean Dynamics in 2017, and a member of the National Academy of Sciences-Loop Current study committee. He is presently also a member of the NSF Ocean Observatories Initiative Facility Board and a science team member of the International GODAE OceanView project.
