Target area (model & observation)
Themes of observational foci Mixing parameterization - Sub grid scale phenomena Ocean monitoring - Upper layer in the equatorial Pacific - Low latitude western boundary currents - Indonesian through flow
Important for climate model Atmosphere - Cloud Ocean - Surface mixed layer mixing - Thermocline mixing Parameterization
Predominance of small vertical scale structures in the velocity field New ocean mixing parameterization schemes is needed Equatorial thermocline mixing
