WebEddy influence is observed to depths exceeding 4,200 m. These deep- reaching mesoscale eddies typically propagate westward past Palau, and as they do, any associated deep flows must contend with the topography of the Kyushu-Palau Ridge. This interaction leads to vertical structure far below the main thermocline. WebOct 1, 2011 · A value of U / c > 1 implies that there is trapped fluid within the eddy interior. Many of the extratropical eddies are highly nonlinear, with 48% having U / c > 5 and 21% having U / c > 10. Even in the tropics, approximately 90% of the observed mesoscale features are nonlinear by this measure. Two other nondimensional parameters also …
