TerryM Posted October 14, 2012 Share Posted October 14, 2012 Cold Octobers in the US while the Arctic experiences anomalous heat. From Tamino's's site: "The fastest warming is during autumn, peaking in October." http://tamino.wordpress.com/2012/10/13/arctic-amplification/ Are the low US temps due to a southerly loop in the Jet Stream, a weakening Polar Vortex, the high ridge over Greenland, or what? Another question arises, are the cold temps felt at similar latitudes around the world, or are they limited to North America. Terry Link to comment Share on other sites More sharing options...

Terry We have seen some impressive Arctic blocking during October over the last decade or so leading to colder temperatures at our latitude. Some years the coldest temperatures relative to the means were found over North America and other years over portions of Eurasia. As you point out, this is occurring with the warmest October Arctic temperatures on record and more October open water there than we have seen before.

Entropy Posted October 15, 2012 Share Posted October 15, 2012 I wonder how the urban heat island effect could be present some months, but not others. Any thoughts? The surface must revert to farmland and forest during October. Link to comment Share on other sites More sharing options...

Entropy Posted October 15, 2012 Share Posted October 15, 2012 Funny how the urban heat island effect is most pronounced over the sparsely populated -- actually completely unpopulated -- Arctic Ocean. Link to comment Share on other sites More sharing options...
ORH_wxman Posted October 15, 2012 Share Posted October 15, 2012 The 80 year trend for U.S. October temperature is actually negative. The only other month that is negative in that time frame is December. Though July is almost dead flat...barely positive. The months that have warmed up the most are March and January. November just behind. Link to comment Share on other sites More sharing options...
