PRELIMINARY June 2010 SST Anomaly Update

I’ve moved to WordPress.  This post can now be found at PRELIMINARY June 2010 SST Anomaly Update
The June 2010 SST data through the NOAA NOMADS website won’t be official for another week, on Monday July 5th. 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 June 2010 presented by the NOMADS website. I’ve also included the weekly data through June 23, 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 put them closer to the La Niña threshold.
Preliminary Monthly NINO3.4 SST Anomalies

Monthly Global SST anomalies, according to the preliminary data, have stalled in their lagged decline, but as you will see with the weekly data, the uptick is temporary and normal.

The weekly NINO3.4 SST anomaly data have dropped just below the -0.5 deg C threshold of a La Nina.

Weekly Global SST Anomalies are declining but there was a minor uptick during the past few weeks.

Thanks, Diane.

Bob, FWIW, back in December 2008 you compared the Southern Ocean graph with an inverted graph of the hours of sunshine at Armagh.

DB: Yup. It was on this thread:

I thought it was a curiosity and was looking for similar curves.

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.
