The Blob Lives: Update from Rick Thoman

Hello Blob fans,
The blob lives! At least in the form of the highest April PDO (Pacific Decadal Oscillation) Index in the 117 years of the JISAO time series (+2.62). Here’s a plot of Mar-Apr 2016 mean SST anomalies, from ERSSTv4 on the left, and on the right the Mar-April 2016 anomalies minus the Mar-Apr 2014 anomalies. –Rick
