Mid-July SST Anomaly Update

I’ve moved to WordPress.  This post can now be found at 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.

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?

Bob Tisdale said...

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?

Bob Tisdale said...

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?

Bob Tisdale said...

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

The Smith and Reynolds SST Posts DOES NOT LIST ALL SST POSTS. I stopped using ERSST.v2 data for SST when NOAA deleted it from NOMADS early in 2009.

Please use the search feature in the upper left-hand corner of the page for posts on specific subjects.

NOTE: I’ve discovered that some of the links to older posts provide blank pages. While it’s possible to access that post by scrolling through the history, that’s time consuming. There’s a quick fix for the problem, so if you run into an absent post, please advise me. Thanks.
