persistent warm over Arctic Ocean, persistent cold over US and continental Asia

I updated my calculation of running 5-day temperature anomalies versus the same 5-day period for the ‘climate normal’ (a.k.a. most recent 30 year period beginning on a “1” year) 1981-2010. These data are from the US NCEP NCAR Reanalysis mixture of observations from satellites, ground stations, aircraft and numerical modeling.

Most striking to me is the Arctic Ocean area persisting warm…
