symmetric anomalies?
Hi,
Does anyone know how to tell ferret to generate "symmetry anomaly fields"?
An example would be the following:
Given SST field extending
from 60S to 60N, plot SSTANO, which is defined as difference
between the north and the south hemispheres (the line of symmetry
being the equator):
SSTANO = SST(from 60S to 60N) - SST(from 60N to 60S)
Its important to note that Lat S should map to the same Lat N,
(i.e give difference between 50S and 50N, etc.)
Likewise one could generate an anomaly plot where the line
of symmetry is a given longitude and w'ed get an east-west
anomaly field.
If anyone has ideas on how to do this please share them with me, -
I'm kindoffa stuck here...
Thanks
Halldor
