Entry, flux, and exit of potential vorticity in ocean circulation.
(Marshall, J and Jamous, D and Nilsson, J), JOURNAL OF PHYSICAL OCEANOGRAPHY, vol. 31, no. 3, pp. pages, 2001.
The flux form of the potential vorticity (PV) equation is employed to derive simple expressions for the boundary and interior flux of PV in ocean circulation using Bernoulli functions. The formulas are discussed and physically interpreted and used to map the flux of PV through a model of ocean circulation.
