hi ,
frends ihad a script for the tropical cyclone may be it will be use ful for
u i think
here you can see where is the centre and pick up the x,y points
after that you have to convert there x,y coordinates into latitude and
logitude coordinates.
These points are for your reference.
Later as you keep the time steps increasing, you can pickup the central lat
and lon simultaneously.
Finally use the draw line command to join all the points.
Here you have to use the x,y coordinate points only.

Hope this will suffice your problem.

'reinit'
'open stn.ctl'
'set grads off'
'set grid off'
'set lat '
'set lon'
'd sea level presure code'
'set strinz 0.1'
'draw title  track of the tropical cyclone'
'set line  1 8 3'
'draw line x1,y1,x2,y2'
'enable print.meta'
'disable print'
  it will use to solve u r problem if there is any doubts please mail me
best regards
