The reason for this is that you've moved the labelbar so far away from
the plot that the whole plot area is now wider than it is high, so
when you set gsnMaximize to True, it rotates it to landscape to better
fill the page.

I assume by "multiplot" you mean that you plan to call gsn_panel? If
so, you can control the rotation by setting the gsnPaperOrientation
resource to "portait" when you set the panel resources.

Or, do you mean you plan to do multiple overlays? If so, then you can
do this in the maximize_output call:

. . .
   vector_wind =
gsn_csm_vector(wks,data_U(lat|:,lon|:),data_V(lat|:,lon|:),vcres)
   overlay(plot_olr,vector_wind)

   pres = True
   pres@gsnPaperOrientation = "portrait"
   maximize_output(wks,pres)

I'm not sure why you are moving the labelbar so far away from the
plot, but if you don't want this, then remove the line:

   res@pmLabelBarOrthogonalPosF = .25

This is because you didn't remove the "pmTickMarkDisplayMode"
resource. You can't use the Lat/LonSpacing resources if this resource
is set to "Always".

I've attached a modified version of your script that:

   - fixes the lat/lon spacing
   - doesn't draw the individual plots
   - moves the labelbar closer to the plot
   - draws everything in portrait mode

See the attached script and image.
