Sounds like a modeling exercise to attempt to tease out the contribution. As I hope to show, the extreme surface temperature anomaly for September 1992 can be tied to the remarkably early establishment of the permanent winter snow cover.

Since 1981, nothing has come close, with only June 2004 and June 2013 being more than 3 SD away from normal.<br /><br />Can't help but wonder if there was any contribution from the eruption of Mt Pinatubo about 15 months earlier. We know the global climate cooled slightly in the next year or two, but perhaps there were circulation impacts too.<br /><br />Look forward to your future posts on this.<br />Richard Jameshttps://www.blogger.com/profile/08313902028896263276noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-25481455761957570702013-09-12T08:10:15.381-08:002013-09-12T08:10:15.381-08:00Was this the year the Equinoix marathon was cancel...Was this the year the Equinoix marathon was cancelled? <br />-MatthewAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-52504857953445367372013-09-11T21:23:26.272-08:002013-09-11T21:23:26.272-08:00We are keeping an eye on this in 2013: http://www....We are keeping an eye on this in 2013: http://www.worldagweather.com/arctic/t2m.html<br /><br />GaryNL7Yhttps://www.blogger.com/profile/15874712728971005352noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-67851049866306208622013-09-11T05:46:49.046-08:002013-09-11T05:46:49.046-08:00There were no operational ensemble forecasts in 19...There were no operational ensemble forecasts in 1992. As I recall we had the NGM out to 48 hours, the AVN out all the way to 72 hour and then a quasi-manual 3-5 day. Someone please correct if my memory is wrong here.

Were there ensembles back then? If so, I wonder what the spread looked like.Climatologist49https://www.blogger.com/profile/04560505931210357679noreply@blogger.com
