We note that the correlation in the limit of zero distance, 𝑅 0 = 0.874, has a natural and important physical interpretation. It is an estimate of the correlation that one expects to see between two typical weather stations placed at the same location.
Thanks, Mosh. I’ve heard you make this claim before, but I fear that I simply don’t understand why two stations next to each other would happen to have a most exact correlation of 0.874 with each other.
Not only that, but your claim is in total opposition to the results of Hansen and Lebedeff. See the graphic at http://wattsupwiththat.files.wordpress.com/2011/02/hansen-distance-vs-correlation.jpg
As you can see, the correlation both varies widely, and with decreasing distance between stations it also generally approaches 1.0, not 0.874.
So … a link to the basis for your claims would be good, as well as an explanation of just how Hansen and Lebedeff got such a different answer from yours.
Regards and thanks,
