[MITgcm-support] [EXTERNAL] Banding, Checkerboarding in KPP Viscosities

[Dimitris Menemenlis]

Hi Ed, I was not questioning the need for a convective adjustment scheme but whether a simpler scheme than KPP, e.g., cAdjFreq/ivdc_kappa might suffice.

Senja, do they instabilities occur within or below KPPhbl?  Are they stable in time and vertical structure or do they oscillate?
