I have<br>this algorithm collecting tropical cyclone center at each forecast<br>time, which I record only at two variables (lon and lat). I also print<br>these coordinates (thru say command) in the terminal. After collecting<br>all the values, I plan to make a track from the coordinates I just<br>collected. I can't think of how I would program this in grads (does<br>grads support fortran syntaxing?) with changing the values of the two<br>variables I have so I would not have veeeery long .gs of just<br>copy-pasting "q w2xy" then connect lines. If only grads support C<br>program/functions or R, it would be easier for me. Just want to ask if<br>anybody have some ideas on this.
