Hi Murray,
Thanks for the introduction.
If this dataset is point observation, you should be able to use the Formula
> Grids > Make flow vectors from u and v data.
When the new window popup, select wind speed and direction in each panel. You
will get the vector display.
Sorry I am out of town for the rest of this month and not able to down the
dataset to test it out.
