Volumetric T-S censuses for summer
(Aug. 15). The images show the
base-10 logarithm of water volume
in cubic meters. Superimposed are
contours of sigma-0 calculated
using the HYCOM/MICOM
equation of state.
HYCOM was run with KPP mixing
and relaxation boundary conditions
to produce the “best” possible
simulation.
Relaxation boundary conditions
caused the simulated census to
more-closely resemble the observed
census. The BC’s act to “form”
water masses that are actually
formed outside of the model
domain, bringing the simulated
census closer to reality.
