August 2008 SST and SOI Update

CORRECTION - November 7, 2008

In the opening paragraph of this post, I make the following statement: “I’ve added graphs of NINO3.4 SST anomaly, since it’s a driver of global temperature anomaly (lag 3 to 5 months), and the Southern Oscillation Index, because it precedes NINO3.4 by a few months.”

The NINO3.4 SST anomaly does NOT always follow the SOI, though it has been doing so for the past few months. They do correlate remarkably well, but there are times when the changes in NINO3.4 will precede the SOI and times when they can become slightly out of synch. Therefore, I’ll retract the blanket statement of the SOI preceding NINO3.4 by a few months.

All graphs are from January 1978 to August 2008.

I’ve added graphs of NINO3.4 SST anomaly, since it’s a driver of global temperature anomaly (lag 3 to 5 months), and the Southern Oscillation Index, because it precedes NINO3.4 by a few months. For those not familiar with the SOI, I’ve also inverted it to permit a comparison to NINO3.4 SST anomaly.

1. NINO3.4 SST Anomaly – Monthly Change = +0.181 deg C

2. SOI – Monthly Change = +6.9

3. Inverted SOI – Monthly Change = -6.9

I’ve also added the following SST anomaly graphs:

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.

Please use the search feature in the upper left-hand corner of the page for posts on specific subjects.

NOTE: I’ve discovered that some of the links to older posts provide blank pages. While it’s possible to access that post by scrolling through the history, that’s time consuming. There’s a quick fix for the problem, so if you run into an absent post, please advise me. Thanks.
