U and V matrices can be 2 or 4d.
Beware, to discern different configuration of U and V (xy, xyz, xyt, xyzt),
we look at the variable of the common
-time which contain the calendar in IDL julian days to which U and
V refered to, in the same way as the variable
-jpt which is the number of time's step to consider in time.
U and V arrays are cut in the same geographic domain. Because of the gap of
T, U, V and F grids, it is possible that these two arrays has not the same
size and refered to different indexes. In this case, arrays are re-cut on
common indexes and the domain is redefined to match with these common
indexes. To avoid these re-cuts, use the keyword /memeindice in domdef.pro
