PRELIMINARY September 2010 SST Anomaly Update

I’ve moved to WordPress.  This post can now be found at PRELIMINARY September 2010 SST Anomaly Update
Sorry this is late. I’ve been working on a project that’s been occupying my thoughts.


The September 2010 SST data through the NOAA NOMADS website won’t be official until October 11. Refer to the schedule on the NOAA Optimum Interpolation Sea Surface Temperature Analysis Frequently Asked Questions webpage. The following are the preliminary Global and NINO3.4 SST anomalies for September 2010 presented by the NOMADS website. I’ve also included the weekly data through September 22, 2010, but I’ve shortened the span of the weekly data, starting it in January 2004, so that the wiggles are visible.

Based on the preliminary data, monthly NINO3.4 SST anomalies are continuing to drop, and the drop has them at -1.5 deg C.
Monthly NINO3.4 SST Anomalies

Monthly Global SST anomalies, according to the preliminary data, are still stalled. With the step up in the South Atlantic and its effect on the North Atlantic, it will be interesting to see how much global SST anomalies will decline.

The weekly NINO3.4 SST anomaly data have dropped again over the past week. They are still below -1.5 deg C.
Weekly NINO3.4 SST Anomalies

Weekly Global SST Anomalies are still flat. There continue to be some minor wiggles, but the Global SST anomalies are still lagging the drop in NINO3.4 SST anomalies.

Hi Bob -

Thanks for the update as always. Just out of curiosity, and no need to post it, but is this transition period still similar to the prior ones, as you chart in this graph?


No need to reproduce it, just curious.

Thanks, as always.

John: 2010 is just about at the point where the 2007 data intersects with week 38. It's still within the bounds of the other transitions. I'll try to remember to update that graph when I post the monthly update.

The Smith and Reynolds SST Posts DOES NOT LIST ALL SST POSTS. I stopped using ERSST.v2 data for SST when NOAA deleted it from NOMADS early in 2009.
