Default Approx 30-40 day periodicity in synoptic pattern this year

There is a marked periodicity in the top (10-day mean) chart, especially
in the westerly index. In previous years periodicities have come and gone
pretty quickly, and I can't remember seeing one quite as marked as this.

It's not a statistical artifact ... it's easy to remember the westerly
spells in early Jan, early Feb, mid-Mar, early to mid April and late May,
and also the blocked spells between.


I'm sure that I would find this interesting if I could only follow it.

Where do you get your backgrounds from?
