Calculations of the local vertical component of relative angular momentum are considered for quasi-geostrophic circulation models. The angular momentum diagnostic measures the net horizontal spin of the flow within an ocean basin and complements traditional budgets of energy, vorticity and linear momentum. In particular, the diagnostic can help identify the role of bottom topographic stresses in driving ocean circulation. Calculations of torque balances are presented for several numerical experiments with single-layer and multi-layer models. Experiments with an idealized continental slope topography develop a cyclonic circulation in the abyssal layer which is driven by a significant topographic form torque.

More about this publication?
  • The Journal of Marine Research, one of the oldest journals in American marine science, publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. Biological studies involving coupling between ecological and physical processes are preferred over those that report systematics. The editors strive always to serve authors and readers in the academic oceanographic community by publishing papers vital to the marine research in the long and rich tradition of the Sears Foundation for Marine Research. We welcome you to the Journal of Marine Research.
