Subtidal Sea Level Fluctuations and Their Relation to Atmospheric Forcing along the North Carolina Coast uri icon

abstract

  • An asymmetric nonlinear ocean model is employed to investigate the oceanic response to moving hurricanes. A turbulent kinetic energy budget is used to parameterize the stress-induced vertical mixing. The results show that the ocean's response to a symmetric storm is stronger on the right of the storm track. Although the maximum speed of the induced current under the storm is not sensitive to the storm's translation speed, the speed does not have a large influence on the temperature structure and the thermocline depth in the wake. Vertical motions associated with the inertia-gravity ossiclations persist in the wake of the storm. A narrow ridge in the thermocline is left in the storm track for fast-moving storms. The results in many respects agree with Geisler's linear solutions. However, vertical mixing produces significant differences in the depth of the thermocline behind the storm. (A)
