[MITgcm-support] vertical diffusion and mixing for unstable atmosphere

[Yuan Lian]

  David, thanks! I actually fixed a problem in my adjustment scheme and 
now it works perfectly.
I will eventually use the one from aim_v23 or better schemes (need some 
modification for
my problems though).

Cheers,
Yuan
