[ncl-talk] Confluent asymptotes in streamline plots

[Lyndz]

Dear NCL-experts,

I have a streamline chart of winds at 925hPa (plotted using this
https://www.ncl.ucar.edu/Applications/Scripts/stream_1.ncl)
The input files have the following dimensions:

dimensions:

time = UNLIMITED ; // (1 currently)

bnds = 2 ;

lon = 144 ;

lat = 73 ;

level = 17 ;

Is there a way to determine the location of an asymptote in a
streamline chart in NCL? If yes, how can I determine this using NCL?

Or is there a way to determine if a confluent asymptote is within a
specific region?

Here's a sample plot showing the an asymptote in a streamline chart:

I'll appreciate any help on this..

Sincerely,
Lyndz
