It's ...Thanks for the comments, Gary and Eric. It's good to think outside the box - I agree that wind pattern shifts could be involved in the seasonal temperature anomalies, and it remains to be seen if we can show what this contribution might be.<br /><br />However, I would argue that the collapse in October variability in Barrow is very likely a direct result of the sea ice loss. Not only does this make perfect physical sense, but in my experience atmospheric circulation anomalies (blocking patterns, etc) do not show this kind of year-to-year persistence even when there is a pronounced regime change. I'll look at this in more detail soon.<br />Richard Jameshttps://www.blogger.com/profile/08313902028896263276noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-65615647174957496292014-08-23T23:17:56.707-08:002014-08-23T23:17:56.707-08:00Are we sure it's the collapse of the ice that ...Are we sure it's the collapse of the ice that has led to the warming? Perhaps most of the warming is due to changing weather patterns. If we have a huge pressure block in Siberia causing southerly flow in all of Alaska then we would see everyone get warmer. The winds would force any ice to stay away from the coast and move more north of Russia. This lack of ice would increase temps by a few degrees (which is why Barrow and Deadhorse are a little higher than Kotsebue) and the variability has collapsed. Eventually any system regime would fall apart by the approaching winter and the ice would build. As an example, think about the weather patterns of this last winter.Eric Lundellhttps://www.blogger.com/profile/17914784378747801359noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-32654323284644396472014-08-23T19:03:18.035-08:002014-08-23T19:03:18.035-08:00The winds (level?) in late Fall may have favored w...The winds (level?) in late Fall may have favored warmer conditions. The ocean temps along the southern and western perimeter of Alaska may have seasonally increased (?) due to changes in density caused by winds and differential water temperature and salinity along the coast. <br /><br />GaryNL7Yhttps://www.blogger.com/profile/15874712728971005352noreply@blogger.com
