[Response: The classical (i.e. Stommel) theory of the subtropical gyre requires that the interior equatorward (Sverdrup) transport that takes place everywhere but a narrow strip
along the western edge of the basin, precisely balance the
poleward transport that takes place in a narrow
boundary current
along the western edge of the basin.
Thus, the subtropical gyre circulation is a horizontal circulation with
poleward mass transport
along the western
boundary, and equatorward transport everywhere east of that, and providing no net northward mass transport integrated across the basin (which is what Bryden et al have done).
Kelvin waves can travel eastward
along the equator and
poleward on the coasts
along the eastern
boundary of the ocean basins, but not in the ocean interior.
