Query: On the effect of small-scale oceanic variability on topography-generated
  currents   Small-scale oceanic motions, in combination with bottom topography, induce
mean large-scale along-isobaths flows. The direction of these mean flows is
usually found to be anticyclonic (cyclonic) over bumps (depressions). Here we
employ a quasigeostrophic model to show that the current direction of these
topographically induced large-scale flows can be reversed by the small-scale
variability. This result addresses the existence of a new bulk effect from the
small-scale activity that could have strong consequences on the circulation of
the world's ocean.
