Nice bruce, Got to use Area and not Extent. Area is better true gauge and extent has lots of static in it I feel. Lag time is 25-30 momths between PDO and S Hem sea ice Area anomalies http://arctic.atmos.uiuc.edu/cryosphere/timeseries.south.anom.1979-2008 PDO and AMO are also seasonal I see. Can see in two normalized charts here. http://www.woodfortrees.org/plot/nsidc-seaice-n/from:2000/normalise/plot/jisao-pdo/from:2000/normalise http://www.woodfortrees.org/plot/nsidc-seaice-s/from:2000/normalise/plot/esrl-amo/from:2000/normalise Reply
