track of a typhoon and minimum central pressure

[mojgan]

Dear All,

I want to draw the track of a special typhoon and its minimum central pressure by grads. I have .ctl and .dat files from WRF run. I don't know how can I do it. I have searched but I couldn't find a way to draw them. Is there anyone to help me? I need your guidance.
I am looking forward.
