<div dir="ltr">L.B.,<div>Another thing you could try if all you want is nicer looking contours in your plots is to obtain a dummy data set that has a different resolution (e.g., RAP, NAM, NARR etc., anything available on the NOMADS sites), then use lterp to regrid your GFS data to a different grid quickly and easily. This would make the contours take on different shapes in your GFS data. I think you would want to regrid to a finer grid, but I'm not 100% sure on that. Try it for a few other data sets and see if you can find something that is to your liking.</div>
