skip() function in x-direction only & not y-direction

[Pablo Romero]

Hi,
Im pretty sure this can be done:

I need to use the skip() function on u,v components in a way that will only skip in the x-direction (longitude) and not in the y-direction (latitude).

example:

the expressions...

'd skip(u,2);skip(v,2)'
'd skip(u,2);v'
'd u;skip(v,2)'

...will all plot "every other" grid point in both x&y directions.

I want to plot "every other" grid point longitudinally (x-direction), while still plotting "every point" latitudinally (y-direction).


so, this is what I want to achieve (in matrix form):


(x1,yn),,(x3,yn),,(x5,yn),,(x7,yn)...(xn,yn),,(x{n+2},yn)
...
(x1,y3),,(x3,y3),,(x5,y3),,(x7,y3)...(xn,y3),,(x{n+2},y3)
(x1,y2),,(x3,y2),,(x5,y2),,(x7,y2)...(xn,y2),,(x{n+2},y2)
(x1,y1),,(x3,y1),,(x5,y1),,(x7,y1)...(xn,y1),,(x{n+2},y1)

How can this be accomplished?

Thanks,
P.Romero
