The
winter (Feb. 15) meridional
|
|
overturning
circulation is graphed for
|
|
six
HYCOM simulations as a function
|
|
|
of
latitude and density. The five
|
|
simulations
without relaxation BC’s
|
|
are very
similar to each other.
|
|
Relaxation
BC’s clearly enhance the
|
|
|
meridional
overturning circulation and
|
|
induces
a deep circulation cell
|
|
associated
with the northward flow
|
|
|
of
bottom water. A significant seasonal
|
|
cycle
exists at low latitudes, with an
|
|
enhanced
winter circulation cell evident
|
between
0 and 20N in all simulations.
