Esper the non-Archiver is Trouet’s supervisor (see url.), so I’ve taken the liberty here of ascribing this clever April Fool’s prank to Esper, though undoubtedly Trouet deserves some credit for her role in pulling off the prank. In a recent post, I alluded to the point that the England precipitation index shown in the Trouet […]
Here are two quotes. The first is from Trouet et al 2009: The increased pressure difference between the Azores High (+3 hPa) and the Icelandic Low (–5 hPa) during positive NAO phases results in enhanced zonal flow, with stronger westerlies transporting warm air to the European continent. The axis of maximum moisture transport and the […]
Trouet et al (2009), Persistent Positive North Atlantic Oscillation Mode Dominated the Medieval Climate Anomaly, published in Reader’s Digest Science a few days ago. Esper the non-Archiver is a co-author. New Scientist breathlessly reported : Europe basked in unusually warm weather in medieval times, but why has been open to debate. Now the natural climate […]
Yesterday, the Economist had an amusing April Fool’s joke, announcing an “Econoland” theme park that “combines the magic of a theme park with the excitement of macroeconomics”. AS PART of a strategy designed to broaden the revenue base, leverage content over new platforms and promote The Economist brand to a young and dynamic audience, The […]
CA reader and commenter Dennis Wingo laconically mentioned the other day that he’d managed to reconstruct early images of the Earth from the moon. The story has received some excellent and very favorable publicity. Dennis wrote to CA: I have been doing some reconstructions of lunar images from the mid 1960’s and reconstructed the famous […]
A delayed report from Thailand on our trip to the Spirit Cave near the Burma border. Speleothems have become a popular proxy in the past decade, making up many new contestants in Mann et al 2008. We’ve discussed speleothems on numerous occasions, making reference to Jud Partin’s speleo in Borneo, a number of Chinese speleos […]
Beckers and Rixen 2003 url is an interesting read in two respects: 1) they present a non-RegEM infilling approach. The method appears to be exactly the same as one that I (independently) implemented and illustrated about a month ago – what I termed “truncated PC”. This was actually the very first thing that I did […]
There has been a good deal of discussion regarding the correlation between temperatures at various locations throughout Antarctica. Several people have looked at the relationship between correlation and distance by creating graphs linking the two. IMO, one of the difficulties in interpreting these is that they are affected by a variety of factors, including the […]
Update Mar 28: Here is Luboš version replacing my much less pretty monochrome version showing the spatial decorrelation of the “Comiso” version of the data recently archived a couple of days ago by Steig. Figure 1. Spatial Correlation for Sample of “Comiso 2009” Antarctic Gridcells Jeff Id has compared this to corresponding surface stations at […]
Back in Toronto after two weeks in Thailand. One of my sons got married and my wife and I spent time traveling with my son and new daughter-in-law and my daughter. I left New York on Monday Mar 9 back to Toronto and left the next morning for Thailand, pretty groggy when I arrived on […]
