PRELIMINARY July 2011 SST Anomaly Update

The July 2011 Reynolds OI.v2 Sea Surface Temperature (SST) data through the NOAA NOMADS website won’t be official until Monday, August 8th. 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 July 2011 that the NOMADS website prepares based on incomplete data for the month. I’ve also included the weekly data through July 27, 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 -0.075 deg C. And that’s a drop from last month.

Monthly NINO3.4 SST Anomalies

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

The preliminary global SST anomaly is +0.140 deg C. I’d be surprised if that was the peak for this year, since global SST anomalies lag NINO3.4 SST anomalies by three to six months.

WEEKLY DATA

The weekly NINO3.4 SST anomalies for the week centered on July 27, 2011 are less than zero at -0.154 deg C. Many models are predicting a La Niña for the 2011/12 ENSO season. Have NINO3.4 SST anomalies reached their high for the year?

Weekly NINO3.4 SST Anomalies

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

Weekly Global SST Anomalies are presently at +0.148 deg C.

    Wondering.. have you found an equally interesting area on/in the World’s ocean that seems to act as a precurser to Nino 3.4?

  2. Bob Tisdale says:

    Pascvaks: I looked around a couple of years ago, but I don’t recall any one place being a consistent precursor to NINO3.4 SST anomalies. ENSO events evolve differently and of course there are Central equatorial Pacific (El Nino Modoki) ENSO events and Central/Eastern equatorial Pacific ENSO events. Why, have you found one?

  3. Pascvaks says:

    Oh no! But it’s one of those things that, intuitively, I just know is out there;-). I’ve been coming here hoping you’d find it and show me how the blinking thing works one day; after you’d found it of course;-). Between the Global Ocean Conveyor, the Solar Cycles and Space Weather, the Global Cloud Cover thing, and all the other widgits, it just seems there’s something somewhere in all that we’re seeing that gives a convoluted signal of which way that NINO3.4 SST Anomoly is going to go next and by how much. I’m one of those “kids” that thinks there’s an answer to everything and there’s no such thing as a stupid question; well.. almost never. Don’t let me waste your time, I know you’re a busy guy. I’ll try to stay quiet in the peanut gallery as much as I can. Sometimes I just have to wave my arm and stammer a question out. Best to you!
