Vertical eddy viscosity

#1 Unread post by zhangtianhao »

Hi all,

I plan to calculate the value of vertical eddy viscosity —— Km. I wonder if ROMS could output this variable, or I have to calculate it by myself?

Thanks.

I believe it is called Akv in the ROMS output.

Kate,

Thanks for your reply. But I remember that the defination of Akv [Input] is vertical viscosity (ν in the picture below) but not vertical eddy viscosity (Km in the picture below) . I wonder that if Akv [Output] is the sum of background viscosity and eddy viscosity (Km + ν in the picture below)?

Cheers,

Hoty

It is the vertical viscosity used by the model, the sum of all the bits that go into it. The details depend on which vertical mixing scheme you are using.

Kate,

Thanks, I will take a try.

Cheers,
