Hawaiian Islands Tidal Flows

Simulated baroclinic tidal velocities around the Hawaiian Islands

Eight tidal harmonics are used to compute the baroclinic and barotropic tides around the Hawaiian Islands. The harmonics are based on climatological mean stratification (T/s) and are computed at several depths. The resulting velocity is computed on a hourly interval at the surface, subsurface and bottom for 2 regions (Big Island and main NW islands).
