LMC Project Modeling Strategy
• Outer domain: HYCOM + NCODA at a
resolution of 1/12° (eddy-resolving) with 32
vertical levels.
• Intermediate domain: IPRC’s nested highresolution (0.04°) Hawaii HYCOM.
• Inner domain: MITgcm (0.01° resolution
with 50 vertical levels).
• Near-field: Jirka’s 6-parameter (turbulence
closure) single-plume model.
