Exploring the Dynamics of Coastal Ocean Extremes: Marine Heatwaves and Landfalling Cyclones

Recorded November 3, 2023 Speaker: Devanarayana Rao, Ph.D. Student Abstract: Marine heatwaves are extended periods of unusually warm ocean temperatures. They present a significant risk to coastal populations and ecosystems. Furthermore, during the peak of hurricane season, the extreme heat content associated with MHWs in the coastal ocean can impact the strengthening of hurricanes making landfall. While both tropical cyclones and marine heatwaves are primarily driven by a combination of physical processes in the ocean and atmosphere, additional processes need to be considered on the continental shelves. These factors include coastal geography, river discharge, and the underlying conditions of the continental shelf. Such factors may contribute to significant changes in the characteristics of marine heatwaves and their relationship to changes in tropical cyclone intensity. Additionally, climate variability can influence the severity of these coastal events. Studying these large-scale connections can enhance our ability to forecast and predict such extremes accurately, leading to more effective strategies for future adaptation and mitigation.
