[MITgcm-support] global 4deg verification

[samar khatiwala]

Hello

I have a query about verification/global_ocean.90x40x15

As shipped, the momentum and tracer time steps in this experiment are set
to different values in 'data':

 deltaTmom = 1200.0,
 deltaTtracer= 43200.0,
 deltaTClock = 43200.0,

Is this because the default is asynchronous time stepping for more rapid
spin up? Once the model spins up to equilibrium, do I set deltaTtracer,
deltaTClock, deltaTmom equal to each other? I have read (Danabasoglu et
al) that in a seasonally forced model, the final spin uip must be done
with synchronous time stepping. Can I set all these deltaT's to 43200.0
sec without the model blowing up? Or does the CFL limit the time step to
1200.0 sec.

Thanks, Samar
