| Abstract: | A 3-dimensional model methodology for predicting the upper ocean currents under the combined influence of Gulf Stream and hurricane is described. Predicted currents are highly dependent on the turbulence closure scheme and nonlinear interactions. New field data will be required to determine the appropriate formulation for turbulent momentum transfer. However, the model points out the importance of nonlinear terms in the equations of motions for preserving the jet-like structure of the Gulf Stream and for properly accounting for interaction between the Gulf Stream and a hurricane. A potentially worst case condition is obtained for the so-called resonant hurricane. |
