Current meter statistics. U and V velocity components have been rotated 30 degrees ccw.
Positive (Negative) u is onshore (offshore). Positive (Negative) v is northwestward (southeastward).

9. Scatterplot of daily 300 m. current observations.

10. Daily average of u,v Velocity components and Temperature.

11. Annual average of u,v Velocity components and Temperature.

12. CONCLUSIONS. The annual cycle at S2 appears well defined:
Spring transition characterized by variable flow (direction and velocity), with decrease of temperature.
Spring Jet characterized by strong Poleward flow, occasionally interrupted by Equatorward flow, with increased in temperature.
Autumn-Winter time characterized by variable flow (direction and velocity), with temperatures remaining warm after the Spring Jet.
