- 10 metre U wind component (short name '10u', ID 165)
- 10 metre V wind component (short name '10v', ID 166)
- 10 metre wind speed (short name 10si, ID 207)
I then calculate sqrt(u1010u*u1010u+v1010v*v1010v), ie, approximate calculate the wind speed from the mean U and V components.
However, I the result is different form the 10 metre wind speed (10si). Why is this?
