This suite of examples uses an older and deprecated method of plotting WRF data. We recommend that you visit the more up-to-date WRF-ARW Online Tutorial for examples of using NCL to plot WRF-ARW data.

WRF_track_1.ncl: Plots storm track data from Hurricane Isabel.

gsn_add_polyline and gsn_add_polymarker are used to draw the markers and lines for the storm tracks, and gsn_text is used to label each position.

You need version 4.3.1 or later of NCL in order to run this example.
