I’ve moved to WordPress.  This post can now be found at September 2009 SST Anomaly Update

MONTHLY SST ANOMALY MAP

The map of Global OI.v2 SST anomalies for September 2009 downloaded from the NOMADS website is shown below.

September 2009 SST Anomalies Map (Global SST Anomaly = +0.23 deg C)

MONTHLY OVERVIEW
Global SST anomalies dropped 0.053 deg C between August and September, the majority of the decline coming from the Northern Hemisphere. The only two datasets with increases were the South Atlantic and NINO3.4. However, the equatorial Pacific continues to show weak El Nino conditions (Monthly NINO3.4 SST Anomaly = +0.87 deg C and Weekly NINO3.4 SST Anomaly = +0.66 deg C). Monthly NINO3.4 SST anomalies rose a small amount (+0.05 deg C) in September, while the weekly data shows NINO3.4 SST anomalies have been decreased slightly over the past few weeks.

A QUICK NOTE ABOUT THE ERSST.v3b GLOBAL SST ANOMALY FOR SEPTEMBER

The Global ERSST.v3b SST anomaly data dropped 0.07 deg C between August and September 2009.

There should be no claims this month about record SST or SST anomaly levels.

John: I lost your comment but the supplier assures me there's no problem.

Hi Bob -

Any thoughts on the bump in the South Atlantic this year to record levels? I don't recall any posts from you dealing with its trends, though I could be mistaken.

Bob Tisdale said...

John: Sorry. Each time I post the monthly update I consider looking into the South Atlantic anomaly over the past year. So far, I haven't done any further breakdowns to see if the high temps are centralized somewhere.

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.

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.
