Trajectory plot

[Charles Seman]

Michel,

Please find attached "plot_hurricane_center3.gs" (an interactive script
to plot the minimum sea-level pressure: you click on the map for the
"left upper corner" and "right lower corner" for the box in which GrADS
will search for the minimum pressure), and "plot_hurricane_track.gs" (an
automated script which searches the entire specified domain, and plots
the min sea-level pressure, max relative vorticity (calculated in
GrADS), and the max wind speed), and "pause.gsf" (GrADS script function
to pause till the "enter" key is pressed).

I hope this helps, and please email me with any questions you might have.

Thanks,
Chuck
