Hurricane wind-driven surface waves on a narrow continental shelf and exposed coast

Tropical cyclones, including hurricanes, have high winds that can generate strong ocean surface circulation and large waves numerous hurricanes form propagate over the Atlantic Ocean interact with continental shelf. Hurricane Florence (2018) impacted east coast of North America after moving across narrow shelf made landfall in Onslow Bay, Carolina, USA. In contrast, Isaias (2020) moved generally parallel to shelf, making Bay along a very different track compared Florence. These provide an opportunity understand generated by storms move open coastal environment on this study, coupled Delft3D-SWAN modelling system is applied numerically simulate wind wave conditions during both Isaias. The simulations are analyzed source terms control dissipation field. model results for Florence, indicated deep water (wind input, whitecapping quadruplet interactions) governed action balance (10–100 m depths), negligible contributions from shallow such as bottom friction. followed same trend, but lower values corresponding speeds smaller heights. addition, crossed approached bay larger were not limited fetch. since fetch-limited west side near fetch study underscore how tracks respect orientation fields impact environments ways. • used two recent landfalling storms. Storms orientations differently.
