VERY PRELIMINARY December 2011 SST Anomaly Update

STANDARD OPENING PARAGRAPH

The December 2011 Reynolds OI.v2 Sea Surface Temperature (SST) data through the NOAA NOMADS website won’t be official until Monday, January 9th. 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 December 2011 that the NOMADS website prepares based on incomplete data for the month. I’ve also included the weekly data through the week centered on December 21, 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 -0.95 deg C, which is still within the range of a weak La Niña. It’s unlikely to reach too much lower since December and January are the normal peak months for ENSO.

Monthly NINO3.4 SST Anomalies

######################

The preliminary global SST anomaly is +0.04 deg C.

WEEKLY DATA

The weekly NINO3.4 SST anomalies for the week centered on December 21, 2011 have not changed considerably over the past few weeks. They are presently at -0.88 deg C.

Weekly NINO3.4 SST Anomalies

######################

Weekly Global SST Anomalies have rebounded. They are presently at +0.061 deg C.

    Bob,

    Have you noticed that….climate scientists are trying to keep separate the sst from the atmospheric temperatures?
    This then would keep the trends flat and allow more time to figure a way to secure more funding while hyping climate change that is NOT of AGW origin.

  2. George says:

    I find:

    The preliminary global SST anomaly is +0.04 deg C.

    and

    Weekly Global SST Anomalies have rebounded. They are presently at +0.061 deg C.

    To be somewhat confusing. When is a global SST not a global SST?

  3. Bob Tisdale says:

    George: One is a preliminary average for the month of December; the other is an average for the week centered on Wednesday December 21, 2011.
