What's the meaning of "isMtke" in the boundaries conditions?

[Kun]

Hi, when using the ROMS MODEL, I found in the ocean.in file boundaries conditions :

LBC(isFsur) == Cha Cha Clo Cha ! free-surface
LBC(isUbar) == Fla Fla Clo Fla ! 2D U-momentum
LBC(isVbar) == Fla Fla Clo Fla ! 2D V-momentum
LBC(isUvel) == Cla Cla Clo Cla ! 3D U-momentum
LBC(isVvel) == Cla Cla Clo Cla ! 3D V-momentum
LBC(isMtke) == Gra Gra Clo Gra ! mixing TKE
LBC(isTvar) == Cla Cla Clo Cla \ ! temperature
Cla Cla Clo Cla ! salinity


I know the physical meanings of Fsur,Ubar,Vbar,Uvel,Vvel and Tvar, but what's the meaning of Mtke??
When peparing bry-file, do I need provide data of Mtke? If need, what should I do to compute Mtke?

Any suggestion will be appreciated.

You only need to provide values if you pick boundary conditions needing boundary values. For your example of Gra and Clo, values are not needed. Also, values would not be needed if you use LMD_MIXING. It would only ever get used by GLS_MIXING or MY25_MIXING.

Thanks, I didn't know that before, and there are no such informaton about in the tutorial book. Thanks a lot again.
