[MITgcm-support] CFL numbers

[David Wang]

Hey folks,

I have two identical runs except the different time stepping. The first 
has a larger deltaTtracer and advcfl_wvel/w_hf_max fluctuate (on 
seasonal cycle) and are generally well above 0.2, the suggested critical 
CFL number that I found in the mailing archive. But the model didn't 
blow up. Another run has a smaller deltaTtracer and its CFL numbers in 
STDOUT are generally below 0.2. What puzzles me is that the multiyear 
mean states of the two runs have nontrivial difference (say, the 
extension of the EUC). Isn't this what I'm supposed to get?

Thanks, D.W.
