Indonesian Throughflow

• k 15 Flow
• k 15 Temperature
• k 15 Salinity

The meridional mass flux integrated across the throughflow at 2, 3, 6 and 8.6 degrees South. The value is the number of Sverdrups flowing from the Pacific to the Indian (positive southward). Note that this quantity is the instantaneous barotropic mass flux at the end of each month, and includes surface gravity waves, which can have significant high frequency components and lead to convergence. The discrepancy between the values at each longitude give an indication of the magnitude of these effects. Dates are relative, the forcing is climatological.

Layer 15 vs Layer 24

During 1977, history data is stored for monthly means, not snapshots. We examine the flow into the Indian ocean, and notice the difference in flow between the 15th layer and the 24th. The near surface flow is strongly controlled by the surface winds, which reverse direction around the seasons. The deeper flow remains along the Australian coast.
