Fall–Winter Current Reversals on the Texas–Louisiana Continental Shelf

Fall–Winter Current Reversals on the Texas–Louisiana Continental Shelf Fall–winter recurrence of current reversal from westward to eastward is identified on the Texas–Louisiana continental shelf using the current-meter Texas–Louisiana Shelf Physical Oceanography Program (LATEX-A) and near-surface drifting buoy Surface Current and Lagrangian Drift Program (SCULP-1) observations in 1993 and 1994. Reversal events roughly satisfy the Poisson distribution with one current reversal nearly every 12 days. Synoptic winds seem responsible for the current reversal events. Other processes such as offshore eddies shed from the Loop Current and river runoff are less important to change alongshore flow direction at synoptic scales. A statistical model is established to predict the synoptic current reversal using the surface wind observations. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Physical Oceanography American Meteorological Society

Abstract

Fall–winter recurrence of current reversal from westward to eastward is identified on the Texas–Louisiana continental shelf using the current-meter Texas–Louisiana Shelf Physical Oceanography Program (LATEX-A) and near-surface drifting buoy Surface Current and Lagrangian Drift Program (SCULP-1) observations in 1993 and 1994. Reversal events roughly satisfy the Poisson distribution with one current reversal nearly every 12 days. Synoptic winds seem responsible for the current reversal events. Other processes such as offshore eddies shed from the Loop Current and river runoff are less important to change alongshore flow direction at synoptic scales. A statistical model is established to predict the synoptic current reversal using the surface wind observations.
