Also, many all-time records are being broken, and obviously in those cases there's no precedent in the century or so of modern climate data.<br />Richard Jameshttps://www.blogger.com/profile/08313902028896263276noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-8627821900259513342019-07-14T11:37:33.783-08:002019-07-14T11:37:33.783-08:00Interesting that a lot of the records we are break...Interesting that a lot of the records we are breaking now were set back in the 70s and before that in the 30s.

I completely agree on the support for widespread heat in 1915; it would be a very interesting study to look at what happened that summer.<br /><br />GHCN-Daily, which is the top source for ACIS, has no data for Haines from 1954 to 1997, so I'm wondering if somehow data from another location made it into the ACIS history for those years. Stranger things have happened.<br /><br />Thanks again.<br />Richard Jameshttps://www.blogger.com/profile/08313902028896263276noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-49984391021111722032019-07-09T18:11:30.881-08:002019-07-09T18:11:30.881-08:00Richard, I use the ACIS2 system primarily to get m...Richard, I use the ACIS2 system primarily to get my data, plus I have checked the scanned coop forms for some of these records and found that they at least are not keying mistakes. There are a suspicious number of really warm temperatures from 1975-78 which I'm trying to figure out. So far there is little corroboration although there were few stations nearby to compare (no other stations in this valley that I've found and no Skagway). Some more distant stations like Juneau and Sitka offer some support. On the other hand the very warm summer of 1915 has lots of support nearby (Klukwan 25 miles inland which is typically 5 or more degrees warmer in summer recorded 99F on July 28) and regional and basically the eastern half of AK was extremely warm that summer (100F in Fort Yukon, 97 in Gulkana, etc). Also, in a biography of Haines pioneer Charlie Anway, that summer was described as very warm and dry, with multiple large wildfires in the are that came close to burning down the town.

A quick look at what I believe is the official Haines record shows 90F in July 1934 and 1936, and as high as 92F (but possibly dubious) in July 1915. I'm not seeing anything higher than that in any month.<br />Richard Jameshttps://www.blogger.com/profile/08313902028896263276noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-28375040677536575102019-07-09T12:43:22.874-08:002019-07-09T12:43:22.874-08:00Nice write-up.

And the warmth was a topic of conversation, though we get it now and then. The chart at the top seems to say that the 90F on the 6th was a record high for July. My search reveals 6 other 90F readings in past Julys plus a 92, a 94 and a 98. The last two are suspect highs from 1975 & 1976 respectively, but it seems likely that even if they were a little "hot" that they were pretty good bet for at least 90. Juneau had 90 and 84 on or close to the dates. This year it was 82 in Juneau on the 6th, 83 on the 5th etc.Jim Greenhttp://williwaw.comnoreply@blogger.com
