This simulation
(301K)
of subpolar sea free convection in a 3.6-km cube is driven by surface cooling
of 200 watts/m/m.
The movie consists of 20 frames at a time interval of 100 seconds.
Blue is an isosurface of temperature
that is .005C cooler than the mean.
Green represents areas of downward vertical velocity exceeding
10 cm/sec. The magenta surfaces are high dissipation zones, usually associated with
high shear.

to descend 2000 meters through the X-Y temperature field, viewing the
horizontal cells of ocean mixed-layer convection as you go. (199K)
The horizontal scales are 3200 m by 3200 m. Red is warm (12.85C) rising
water, and blue is cooler (12.83C) sinking water.
Sail in a submarine (216K)
through vertical plumes of ocean mixed-layer convection in the
fluctuating X-Z temperature field
in the Golfe du Lyon in late winter. Vertical scale is 2000 m, and
the horizontal scale is 3200 m.
Red is warm (12.80 C), and blue is cold (12.78 C).
