Hi,
I want to plot the current velocity simulated by my ocean model. The
model has a curvilinear grid (i.e. the grid-spacing in the x- and
y-direction is not equal for all grid cells, and furthermore the x- and
y-directions are not along the lat- lon-circles).

In case you want to try out, I attached  the two velocity components for
a selected region covering  the Gulfstream.

Many thanks in advance!
