It might be a bit more rigorous to divide the tie counts among the number of years in the tie. However, the 1954-present total number of records (by my method) is not greatly different between stations: it varies from 1670 at Bettles (fewest ties) to 1989 at St Paul (most ties). Presumably my method correspondingly overweights the more maritime stations in the aggregate analysis (top 4 figures).<br />Richard Jameshttps://www.blogger.com/profile/08313902028896263276noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-22396835577899767762015-08-22T22:39:58.712-08:002015-08-22T22:39:58.712-08:00Richard, how did you handle ties?

Even though they are not too close to each other, they still have huge differences that seem more related to regional climate than the general pattern.

They are seperated by over 100 air miles. And they do have different climates: Gakona consistently gets colder temperatures and has some rain shadowing from the Chugach mountains. The only similarity is that both are in river valleys and both are at about the same latitude.<br /><br />I would compare Talkeetna to Willow, Trapper Creek, or maybe Cantwell.Eric Lundellhttps://www.blogger.com/profile/17914784378747801359noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-83319327554075368972015-08-20T17:45:02.366-08:002015-08-20T17:45:02.366-08:00Tyler, for the purpose of this study I defined the...Tyler, for the purpose of this study I defined the records relative to the entirety of the period shown, so this removes the effect you're describing. For example, if the Feb 10 max temp record (1954-present) is 50F, this is the level that must be attained in any of the years to add a count on the chart. 50F is the record to be beaten in 1960 even if it didn't occur until 2010; so the records look forward in time as well as back.<br /><br />In day-to-day experience with evolving historical records, you're of course correct that the rate of setting records would generally diminish over time if the climate were unchanging.<br /><br />Thanks for reading.<br />Richard Jameshttps://www.blogger.com/profile/08313902028896263276noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-60078107500849337882015-08-20T17:01:52.419-08:002015-08-20T17:01:52.419-08:00Another factor going into this is the number of te...Another factor going into this is the number of temperature records hit will decrease as more data is produced. This will not effect the data that shows the warming trend when high records continue to be broken but could exaggerate the effect on the cold end.Tylernoreply@blogger.com
