Summer (August 15) T along
65W to a depth of 500m. The thick
line is the mixed layer base.
These cross-sections illustrate the
subtropical mode water (STMW).
All HYCOM hybrid-coordinate
simulations produce 18-degree
water while HYCOM run in
MICOM mode produced STMW
that is too cold (as does MICOM
2.8 – not shown).
