The ventilated thermocline model of Luyten et al. (hereafter LPS), (1983) is reformulated in the quasigeostrophic approximation. The quasigeostrophic solutions with zonal outcrop lines capture the salient features of the solutions of LPS. When the outcrop lines are sufficiently nonzonal, the quasigeostrophic solutions resemble those of Parsons (1969), Veronis (1973), and Huang (1984), resolving an inconsistency in Parsons' solution. But an attempt to close the quasigeostrophic solution having two moving layers with a western boundary current in which friction is parameterized as a linear drag coefficient results in an ill posed problem. The paper concludes with a comparison of cross-gyre ventilation in the quasigeostrophic and LPS formulations.

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.
