Identify Eddies #14

Hi！

For TrackEddy，I don't know if I need to expand the vortex recognition results in order to ensure the correctness of the boundary value.If so, what are your recommended values for indenting for a region of 12°×12°? Thanks for your reply!

hi @qjuanr, a friendly remark: no need to address the issue with "Prof" as it subconsciously may preclude some people from responding. (For example myself as I am not a professor.)

Thank you for your suggestion！I feel sorry about this and I have modified my answer. Looking forward to your reply!

Hello, I appreciate that @navidcy. I'm with @navidcy, I'm not a "Prof" and I'm more than happy to have a more friendly - easy going conversation.

Regarding your question, if you can, I will suggest to expand the boundary if possible, at least the number of grid points that your eddies are (possibly a good idea will be to use the Rossby radius of deformation at the boundary). If you can't, I will otherwise recommend to use a small vertical step in the identification (~1cm). Having a small step generally helps to better identify eddies in general, but it will make the computation more expensive.
