Well they don’t call it the Pacific DECADAL oscillation for nothing.
Much like the AMO, there's usually still windows of opposite expression in the middle of broader phases. In other words it's not unusual to get a year of +PDO within a broader regime of -PDO. Easy to fact check this:
https://oceanview.pfeg.noaa.gov/erddap/ ... e?time,PDOThe last -PDO had many, many periods of positive values. PDO was positive from January to May 2010. Most of 2005. Even the very positive 2014-19 regime had negative values in 2016, 2017, and 2018. June 2018 (a 318 ace season) had a pdo of -0.5. It’s just surprising that we haven’t managed even a single positive monthly even within the context of a very strong negative regime.
The last positive monthly occurred in the 2010s. Just nuts.
