- Summary
- A linearised model of Csanady (1976) for the time-averaged mean flow on a continental shelf is applied to the New Zealand west coast continental shelf. The means are time averages over time scales that are long relative to that of local atmospheric forcing. Forcing of the flow is via the sea surface elevation (specified from deep ocean steric levelling with adjustment for boundary effects), mean winds, and thermohaline forcing (specified by observations and determined by the strong fluctuating flow, the time average of which is the weaker mean flow). The main flow components are found generally to be caused by forcing by the sea surface elevation and local winds. North of latitude 42
