TRR 181 Special Colloquium "Barotropic transport in the ocean"
The TRR 181 special colloquium is a new seminar for esteemed guests. It is held in Hamburg on announcement and is followed by a small reception. As usual, it is broadcastet online for all members of the TRR.
The TRR 181 special colloquium is held by Richard Greatbatch (GEOMAR) on June 4, 3 pm at Universität Hamburg, Bundesstr. 53, room 22/23.
Abstract
Different mechanisms governing barotropic transport in the ocean are discussed, starting with the traditional flat-bottom Sverdrup balance, then moving on to discuss bottom pressure torque and the role of non-linearity in the momentum/vorticity balance. A new method for diagnosing the mechanisms driving transport in a high resolution ocean model is introduced. Of particular interest is the role played by the mean flow advection and the Reynold stress terms. Both of these are shown to play a role in Viking20, a 1/20th degree nested model of the North Atlantic Ocean, particularly in the dynamics of the Gulf Stream recirculations. The results also suggest a role for mean flow advection in the dynamics of the so-called Lavender gyre in the Labrador Sea.
