[ncl-talk] monsoon trough

[Dennis Shea]

"depict" => Draw

If you know the lat/lon locations of the trough:

   lat_trough = (/lat1,lat2,...,latN/)
   lon_trough= (/lon1,lon2,...,lonN/)

[1] draw a map with gsnDraw/gsnFrame set to False


    plot = gsn_csm_map_ce(wks,res)

[2] use gsn_polyline or gsn_add_polyline

        dum = gsn_add_polyline(wks,plot, lon_trough,  lat_trough, pres)

[3] Draw/Frame

There are numerous examples at:

In particular,
