I see that Adam has sent an answer concerning how to get a realistic size for each filled circle. I have just created an example that has a very crude representation of a possible hurricane track -- 3 locations only. It modifies the example polyg_8.ncl. Your situation is actually simpler than polyg_8, because you basically just need to draw one circle at a time. So you can see that mostly I just removed code from the original example.

I want to show the size of the storm. Do you have any suggestions on how to do it using the example you sent me?

So for example when is closer to the water I expect the width of the marker to be bigger and smaller as it approaches closer to land. Is there any function that shapes markers according to lat lon and radius.
