Always interesting before peak TC season to compare SST with recent years (difference plots show it best). 2020 (at this point) shows the following compared to:
2019: +AMO, -ENSO
2018: ++AMO, -ENSO, +IOD
2017: -AMM but also -ENSO
2016: Slight +AMO, --PDO
We'll see how it evolves! pic.twitter.com/cqFNLiUUis
