Subject: | [mget-help] Eddies and southern hemisphere - cyclones versus anticyclones |
Date: | Sun, 28 Oct 2012 12:20:44 -0400 |
Hello,
Thank you for this great tool! I thoroughly enjoy MGET.
I have a question about the polarity of eddies identified in the
"Okubo-Weiss Eddies in Aviso SSH Product" tool, using MGET 0.8a30.
Does the algorithm correct for polarities for the Southern Hemisphere
versus the Northern Hemisphere. I.e., reading the tool help very
naively, it states that "anticyclonic is concave down, cyclonic is
concave up". Shouldn't this be switched for the Southern Hemisphere?
Does the tool automatically flip the polarities or do I have to
manually alter my interpretation of -1,1 from the polarity outputs?
Thanks again,
Robert Rankin
