[MITgcm-support] Wind-driven buoyancy flux (WDBF) in KPP

[Dimitris Menemenlis]

Liam, I copy your message to Mar Flexas Sbert and Andy Thompson, as they have
also expressed interest in studying wind-driven mixing near fronts using MITgcm.

Honestly, I had not realized that KPP is not set-up to deal with dense water in the
surface level.  What about the local Richardson number term in Ri_iwmix?
Is this not sufficient?

This issue arises as down-front winds drive dense water over light water, which triggers convection in the real ocean, but doesn't in the KPP scheme as the non-local convective adjustment is only switched-on for destabilising surface forcing.

Has anyone implemented this and would consider sharing their code?  I would be happy to help to get it added as a standard option in the model code.
