Re: question about plotting typhoon best track

From: Dennis Shea <shea_at_nyahnyahspammersnyahnyah>

The unique_1.ncl was written long before the str_* functions were
created. The attached script uses "str_get_col" to extract some of
the data. You can expand as needed.

The unique_1.ncl predefined storm names and numbers.
You will have to create code that performs that task.

Anyway, the attached script should get you started.

Good luck
