VERY PRELIMINARY June 2011 SST Anomaly Update

The June 2011 Reynolds OI.v2 Sea Surface Temperature (SST) data through the NOAA NOMADS website won’t be official until Monday, July 1th. Refer to the schedule on the NOAA Optimum Interpolation Sea Surface Temperature Analysis Frequently Asked Questionswebpage. The following are the preliminary Global and NINO3.4 SST anomalies for June 2011 that the NOMADS website prepares based on incomplete data for the month. I’ve also included the weekly data through June 22, 2011, but I’ve shortened the span of the weekly data, starting it in January 2004, so that the variations can be seen.

PRELIMINARY MONTHLY DATA

Based on the preliminary data Monthly NINO3.4 SST anomalies are at -0.011 deg C.

The preliminary global SST anomaly is +0.155 deg C.

WEEKLY DATA

The weekly NINO3.4 SST anomalies for the week centered on June 22, 2011 are just above zero at +0.032 deg C. They well within ENSO-neutral range.

    Bob,

    There are some material inconsistencies in the Nino3.4 index, depending on which source is used to download historical data. What is your take on these disconcerting discrepancies?

  3. Bob Tisdale says:

    sky: I assume you’re asking about the differences between the NOAA ERSST.v3b-based and the Hadley Centre’s HADISST- and HADSST2-based NINO3.4 SST anomalies. The major differences between them occur in the pre-1950s era, and those are due primarily to the methods used to infill the missing data. Also, NOAA apparently is of the opinion that the eastern equatorial Pacific SST anomalies should have a trend, but the Hadley Centre’s data there is pretty flat. Which would be consistent with an area dominated by upwelling, an upward trend or no trend? GCM hindcasts have a trend in the eastern equatorial Pacific but I find it hard to find anything that GCMs do right.
