If they've got the timing of the big wiggles right, that would be a good thing.Bob Tisdalehttps://www.blogger.com/profile/15462377647970214137noreply@blogger.comtag:blogger.com,1999:blog-2220966763638300672.post-62959918748409685312009-10-29T16:38:35.704-04:002009-10-29T16:38:35.704-04:00A bit of an eyeball correlation and certainly just...A bit of an eyeball correlation and certainly just simply an observation, but their ENSO reconstruction appears to start experiencing significant variance increases around 1910, right when the temperature anomalies start their upward march (at least when looking at the 1880 - present HADSST).<br /><br />I wonder what happened then.Johnnoreply@blogger.comtag:blogger.com,1999:blog-2220966763638300672.post-65545834680249716532009-10-29T15:21:55.364-04:002009-10-29T15:21:55.364-04:00Robin: Thanks for the link.

Monthly anomalies are: June 0.113, July 0.188, August 0.128, September 0.07, October 0.041 (until 24.10.) Anomalies are versus 2003-2008 baseline.<br />Unisys gif also does not indicate any warm-up of North Atlantic, but quite the opposite: http://weather.unisys.com/archive/sst/sst_anom_loop.gif<br /><br />Juraj V.Unknownhttps://www.blogger.com/profile/01284441733104541252noreply@blogger.comtag:blogger.com,1999:blog-2220966763638300672.post-3933306904174865792009-10-27T14:08:33.332-04:002009-10-27T14:08:33.332-04:00John: I haven't the slightest idea how or why...John: I haven't the slightest idea how or why the preliminary data shows up over a week in advance, but it does some months.

There are at least 3 weeks of Oct reading at .46 or below and the new level for the month appears to be .56ish. <br /><br />Somehow I can't see that being accurate. <br /><br />Plus, how can it even be preliminary without October 28th's reading, which won't get published until Nov 2 or so anyway?Johnnoreply@blogger.com
