Surface/Mixed  Layer Dynamical Fields
• Primary Comparisons:
– Five model simulations compared to Levitus climatology
• HYCOM KPP
• HYCOM KPP (theta-S)
• HYCOM K-T Implicit
• HYCOM K-T MICOM Mode
• HYCOM K-T Explicit
– The primary comparisons evaluate the primary vertical mixing schemes
plus the consequences of selecting theta-S advection (where T is not
conserved) instead of T-S advection
• Other Comparisons:
– HYCOM K-T MICOM mode vs. MICOM 2.8
• Demonstrates expected strong similarity between the models
– HYCOM K-T 1 vs. HYCOM K-T 2
• Compare performance of the two hybrid K-T mixed layer models
– HYCOM KPP (Rlx. BC) vs. Levitus Climatology
• Compare “most realistic” simulation to observations
