PDO has nothing to do with the ongoing trashy pattern. It’s an element of subseasonal variability tied to circulation/andes terrain torque in the SH and echoes of prior MJO/BSISO activation at inception of E-Hem monsoonal forcing a month ago on the in-situ AAM budget conspiring to produce pseudo Niña type circulation in the extratropics. Horrible timing of all subseasonal elements here.
However, as seasonally-linked teleconnective modes mature heading into late summer/autumn and low frequency ENSO coupling becomes more efficient near/after the fall equinox, the pattern will begin resembling that of a canonical Niño more consistently.
Nasty day but I'm off on a quick trip to Beaver Lake Arkansas where it's also hot. Here's the conditions back home.
