The cold water must have sunk in Arctic regions and slowly flowed
equatorwards along the bottom.

[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).
Extratropical cyclones have three stages of expansion: the developing stage, in which an undulating wave develops
along the front; the mature stage, in which sinking cold air sweeps
equatorward west of the surface low - pressure centre and ascending warm air moves poleward east of the cyclone; and the occluded stage, in which the warm air is entrained within and moved above the polar air and becomes separated from the source region of the tropical air.
The arid conditions found
along the western coasts of continents in subtropical latitudes are further enhanced by the influence of the
equatorward surface air flow on the ocean currents.
The experimental behavior supports the storm scenario the traveling atmosphere disturbances (TADs) of auroral origin and changes in the thermospheric wind are the main physical mechanisms driving
equatorward - directed and vertical winds which in turn move the plasma
along the magnetic field lines and raise the ionospheric peak height.
The increased
equatorward wind at middle latitudes tends to push the ionosphere higher up
along magnetic field lines, where the loss rate is lower.
Stronger downward transport of water mass must be balanced by upwelling somewhere else, and this occurs in regions of divergence (Ekman suction)-
along the
equatorward travelling arms of the gyres, and
along the equator itself.
