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…

Arctic20140206The most recent map (that does not include forecast data) has the warm anomaly along the US west coast turned to cold anomaly. So, the whole US is in the cold in the most recent 5 day average. The warmest temperatures over the Arctic Ocean are 17 C above the 1981-2010 average for this 5 day period.

Here’s the situation over the US for the region bounded by 70 to 105 longitude west and 38 to 55 latitude north…

About the author Jason Box

Dr. Jason Box has been investigating Greenland ice sheet sensitivity to weather and climate as part of 23 expeditions to Greenland since 1994. His time camping on the inland ice exceeds 1 year. Year 2012 brought a deeper level of insight as the scientific perspective shifts to examine the interactions ice with atmospheric and ocean systems, including the role of fire in darkening the cryosphere. As part of his academic enterprise, Box has authored or co-authored 50+ peer-reviewed publications related to Greenland cryosphere-climate interactions. Box instructed climatology courses at The Ohio State University 2003-2012. Box is now a Professor at the Geological Survey of Denmark and Greenland (GEUS). Box was a contributing author to the Nobel Peace Prize-winning Intergovernmental Panel on Climate Change 2007 4th assessment report. Box is also the former Chair of the Cryosphere Focus Group of the American Geophysical Union.
