Also, it should update every day from now on.<br /><br /><br />Richard Jameshttps://www.blogger.com/profile/08313902028896263276noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-5326829547414674442013-08-14T09:25:31.633-08:002013-08-14T09:25:31.633-08:00Thanks Mike for the links to Polar weather.

Will explore them both more.<br /><br />Is there an overall or master website for Polar weather and links you've accessed?

It is a treasure trove for the curious. http://www.esrl.noaa.gov/psd/arctic/observatories/summit/browser/#content<br />You can watch short term temperature trends ( a few days, etc) and watch the creation of cold air masses. The websites you provided also are a great watching tool as you will see that usually when Greenland warms in the fall cold air is transported/migrates north over the arctic sea ice.<br />http://psc.apl.washington.edu/northpole/index.html<br />This link takes you to several live surface sea level weather data for the high arctic.Mikehttps://www.blogger.com/profile/14314188127716465153noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-28216905436286802152013-08-13T19:09:55.311-08:002013-08-13T19:09:55.311-08:00Here's another from the link above:

Makes sense that cooling over Greenland would be a trigger. Do you have any useful links for watching these events unfold?<br /><br />I think Gary linked to this page a while ago, but I occasionally look at this site showing the Arctic basin average temperature:<br /><br />http://ocean.dmi.dk/arctic/meant80n.uk.php<br /><br />If the data are reliable, it seems to have been a cold summer, with an early onset of autumn freezing conditions.<br />Richard Jameshttps://www.blogger.com/profile/08313902028896263276noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-75952867277315513052013-08-13T13:19:43.466-08:002013-08-13T13:19:43.466-08:00All this summer talk makes me want to spell out a ...All this summer talk makes me want to spell out a wintery comment. The first or second short impulses of "arctic" air have been rolling off greenland. When I was in college 10 years ago I used to watch for the "critical" tipping point where solar input over Greenland was less than overall radiation loss (this is closely correlated to sun angle but is moderated by storm systems). (Usually around late July to mid August) When this happened cold air masses (relative to everything else in the area) would form. As these airmasses increased in depth then would eventually flow out north over the arctic sea ice. Over the arctic sea ice now days there are webcams and you can see that the melt ponds are freezing over and surface air temperatures are dropping down into the mid 20's. Shortly thereafter "modified Greenland arctic air" over the sea ice would also start to deepen and loose energy. And thus winter is born in the high arctic.Mikehttps://www.blogger.com/profile/14314188127716465153noreply@blogger.com
