I am trying to plot some trajectories using NCL Version 5.0.0 for Windows.
Something strange happens for trajectories that cross the Greenwich meridian. Instead of continuing directly over the meridian the curve double backs and goes around the globe to make the connection. I wouldn't want to go with an airline that did that!
I attach my NCL script, the small input NetCDF file and a PNG plot of the output. There are 14 trajectories in the input file, each has 145 points. I am using gsn_polyline to plot the trajectories.
