Project 7 – Oscillations

How does one shut down the Atlantic Meridional Overturning Circulation (AMOC)?

There are two projects this time, the latter was suggested by Marc. Both use the global 4 degree setup:

• Systematically reduce the salinity restoring north of 50°N, and find out at what level the AMOC is shut down, and how long it takes. Then repeat the same experiment with the winds over the ACC increased by 20%. Does that stabilize the AMOC?
• increase the salinity restoring in the tropical Atlantic (20°S-20°N) and find out at which level the AMOC shuts down, and at which level it reverses direction.

Hint: doubling taux south of 12°S is done by: vs.surface_taux[:, vs.yt < -12] *= 2
