>Mid-May 2009 ENSO and AMO Update


NINO3.4 SST anomalies have continued their rise. They are still within ENSO neutral temperatures and have reached (approximately) the levels they had climbed to last July/August.

I’ll use the North Atlantic SST anomalies as a proxy for the AMO. As noted in earlier posts, to illustrate the Atlantic Multidecadal Oscillation, the NOAA Earth System Research Laboratory (ESRL) simply detrends North Atlantic SST anomaly data, but they do this to a long-term SST anomaly dataset. Since the OI.v2 SST dataset that’s updated weekly begins in 1990, it does not seem appropriate to detrend that North Atlantic dataset.

North Atlantic SST anomalies appear to have ended their precipitous decline. They are now hovering at approximately +0.07 deg C.

The OI.v2 SST data is available through the NOAA NOMADS system:

    >Bob,Tim lint here, found some links, as per my last comment and your request.Nature (27 July)2006 ? Atlantic ocean floor tectonic faults called detachment faults.http://www.iceagenow.com/Detachment_Faults.htmhttp://www.iceagenow.com/Ocean_Warming.htm“numerical model, based on the current position of the continents, the structures of the Earth’s mantle obtained through geophysical measurements, and the –current displacement rates on the surface–” linkhttp://www.sciencedaily.com/releases/2009/01/090122100828.htmhttp://www.sciencedaily.com/releases/2008/01/080103144448.htmSATELLITES RECORD WEAKENING NORTH ATLANTIC CURRENT link:http://www.nasa.gov/centers/goddard/news/topstory/2004/0415gyre.htmlhope we find something but Google comes up blank.
