Given the question below, how would the kinematic momentum flux be at the surface layer?
For letter a, why would it be that way (positive, negative, or 0)?
Based on the answer below:
I’m not sure if I’ve done it correctly, but this is how I answered it based in your comment below.
- First, I assumed that $\overline{u’w’}$ = $\overline{w’u’}$. So is this something like the mixing of horizontal momentum into areas of lower wind speed (as is the case in the surface layer)?
