Vertical Shear Plus Horizontal Stretching as a Route to Mixing

The combined effect of vertical shear and horizontal stretching leads to thin, sloping structures in tracer fields, whose vertical length scale is much smaller than their horizontal length scale. These structures are then vulnerable to vertical mixing processes. This effect needs to be taken into account when interpreting the horizontal structure of oceanic and atmospheric tracers and may explain recent oceanographic observations.
