>Mid-May 2009 ENSO and AMO Update

>NINO3.4 SST ANOMALIES

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.

AMO

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.
