Restrictions
The norm is calculated on points TTo do this calculation, we average
field U and Von points T before calculate the norme. At the edge of
coast and of domain, we can not calculate fields U and V at points T,
that is why these points are at value !values.f_nan.
When we calculate on a reduce geographic domain, field U and V have not
necessarily the same number of point. In this case, we recut U and V to
keep only common points. We profit of this to redo a domdef which redefine
a geographic domain on which fields U and V are extracted on same points
To know what type of array we work with, we test its size and dates
gave by time[0] and time[jpt-1] to know if thee is a temporal dimension.
Before to start norme, make sure that time and jpt are defined how
they have to!
