We also find downwelling along the outermost boundary of the Southern Ocean where cold Antarctic water sinks below warmer South Pacific and South Atlantic waters.

The process is that of a single large mantle plume rising in one hemisphere and downwelling in the opposite hemisphere ( Fig . 4 ).
23.
A soft spot just south of Greenland is where the initial step of downwelling occurs, nicknamed the " Achilles Heel of the North Atlantic ".
24.
The downwelling over the nightside causes adiabatic heating of the air, which forms a warm layer in the nightside mesosphere at the altitudes 90 120 km.
25.
Air rising will expand and cool resulting in a cold summer mesopause and conversely downwelling air results in compression and associated increase in temperature at the winter mesopause.
26.
Its dark collar seems to mimic the silhouette of a small fish, while the rest of its body blends into the downwelling light via its ventral photophores.
27.
At altitudes 90 150 km the Venusian air moves from the dayside to nightside of the planet, with upwelling over sunlit hemisphere and downwelling over dark hemisphere.
28.
An additional benefit of this method is that the increased salt content of the melting ice will tend to strengthen downwelling currents when the ice re-melts.
29.
In the downwelling model, mantle downwelling, possibly due to mantle convection, causes compression and thickening of the crust, creating the compressional elements of tessera terrain.
