A Study of the Bottom Boundary Layer of the Florida Current

A Study of the Bottom Boundary Layer of the Florida Current This is a report of an experiment designed to study the bottom boundary layer of the Florida Current at a representative site in the Straits of Florida. The objectives of the experiment were 1) to determine the bottom frictional stress 0, and 2) to determine whether the bottom boundary layer is a turbulent Ekman layer. A typical value of the bottom stress 0 was found to be ~0.2 dyn cm2. A mean veering of ~10 in the correct sense was observed in the logarithmic layer. No mean veering was observed above the logarithmic layer; this is believed to be a consequence of the strong modulation of the bottom current by the diurnal tide. The implication of 00.2 dyn cm2 is considered in a simplified model of the Gulf Stream current system; this analysis suggests that, dynamically, the role of bottom friction is rather small. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Physical Oceanography American Meteorological Society

Abstract

This is a report of an experiment designed to study the bottom boundary layer of the Florida Current at a representative site in the Straits of Florida. The objectives of the experiment were 1) to determine the bottom frictional stress 0, and 2) to determine whether the bottom boundary layer is a turbulent Ekman layer. A typical value of the bottom stress 0 was found to be ~0.2 dyn cm2. A mean veering of ~10 in the correct sense was observed in the logarithmic layer. No mean veering was observed above the logarithmic layer; this is believed to be a consequence of the strong modulation of the bottom current by the diurnal tide. The implication of 00.2 dyn cm2 is considered in a simplified model of the Gulf Stream current system; this analysis suggests that, dynamically, the role of bottom friction is rather small.
