How Strong Was That El Niño or La Niña? – No One Knows For Sure

Posted on January 14, 2016 by Bob Tisdale

We recently discussed and illustrated how the differences between sea surface temperature datasets prevented us from knowing which of the recent strong El Niño events (the 1982/83, 1997/98 or 2015/16 El Niños) was actually strongest.  See the post here. That … Continue reading →

The Recent Westerly Wind Burst in the Western Equatorial Pacific Could Help to Strengthen the 2015/16 El Niño

Posted on May 18, 2015 by Bob Tisdale

The graphics at the NOAA GODAS website were running a few pentads (5-day periods) behind when I published the May 2015 ENSO Update.  They’re caught up now, and the Hovmoller diagram of the surface zonal wind stress along the equator, … Continue reading →

Wow! ECMWF Long-Term Weather Model Is Predicting a Super El Niño and I Mean Super

Posted on May 16, 2015 by Bob Tisdale

I was notified today of the rather remarkable plume of ENSO forecasts for 2015 from ECMWF (European Centre for Medium-Range Weather Forecasts).  See their System 4 ENSO region sea surface temperature anomaly forecast webpage here.
