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.

    >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.

  3. Bob Tisdale says:

    >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.
