[gradsusr] Question on computing wind 10 m from gfs

[Andrea Tateo]

Hello,


I downloaded GFS data included the following 25 variables:

Number of Variables = 25
      clwmrprs  21  0,1,22  ** (1000 975 950 925 900.. 300 250 200 150

I would like to calculate the wind speed and direction at 10m.
It is possible to do this by means grads?

Thank you very much for your help
