What is the principle of the WRF model to calculate the wind profile？

[ChristianW]

Hello,
I can extract the wind speeds corresponding to different eta-levels by wrf-python and thus plot the wind profile, but my problem now is that I don't understand how WRF uses the friction velocity u* and the roughness length z0 computed in Surface Scheme to calculate the wind speed values for different vertical layer heights?
Thanks, and i hope to get answers from all of you.

Hi,
You may be able to find the answer in the WRF Technical Note, or inside the surface scheme code (if you haven't already looked there), or the surface driver code.

Thank you for your answer.
