To calculate direction with Uwind and Vwind

Hello Jeremy,
If you're looking for a vector display, then it's 'd u;v' where u and v
represent your uwind and vwind components.

If you're looking for a direction in degrees, then try formula--
        deg = 180+atan2(u,v)*(180/pi)

This should give you "direction from." Remove the 180+ for "direction
toward."

Good luck!

Hello,

I seek a formulate to calculate the direction of the moderate wind  to the
data Uwind and Vwind component coming from GFS on Nomads.
I did not find any formula on the Web, can you help me?

Thank you in advance.
Good day.
