Lodovica,

There are 2 functions:
TANG(V) outputs the scalar tangential wind component, and
TANGV(V) is the vector tangential wind.

In gdcross, you could use:
GFUNC    = tang(wnd)
or 
VECT    = tangv(wnd)


wnd in the above would be the total wind composed from the U and V
components. You could also use the geo, age, etc.
