>Mid-July SST Anomaly Update

>This post uses weekly SST anomaly data (OI.v2) available through the NOAA NOMADS website:

The NINO3.4 SST anomaly is at 0.88 deg C, the same value it was two weeks ago.

Global SST anomalies have dropped a little over the past few weeks.

It is likely that NINO3.4 SST anomalies will increase over the next four to five months. It is unlikely (but not impossible) for the Global SST anomalies to continue their decline while NINO3.4 SST Anomalies are rising.

  1. >Hi Bob,The SOI is continuing to go positive, as shown here: http://www.bom.gov.au/climate/enso/On July 8, the last time they updated the page, they said that the SOI had gone positive because of local weather over Tahiti. Yet the SOI has continued to rise. Have you found gridded daily or weekly sea level pressure data?

  2. Bob Tisdale says:

    >climatechange1: I haven't kept track of the SOI for six months. Back then I used the Australian BOM data. Sorry, I don't have a link for daily or weekly SLP data.

    >Bob, Does ARGO have the ability to collect SST data?

  4. Bob Tisdale says:

    >d: The ARGO floats cycle from the surface to depths of 2,000 meters every 10 days, I believe. So there would be surface readings every ten days per float.There are other float datasets. TAO, for example, has been monitoring SST and other variables of the tropical Pacific since 1979.

    >Why is Wednesday chosen for centering? Does it matter? are there significant variations on that timescale?

  6. Bob Tisdale says:

    >Andrew: I believe Wednesday was chosen so they can update their weekly data on Mondays.
