Nice severe-weather jet we're having over the US this week, aren't we?
Sucker swings in from way down low off Baja, below 30N, where you don't
normally see it.

Watch that bugger swirl over Hawaii, a big sink spiral for the strong,
broad, persistant convection to the southwest. It buckles the
trans-Pacific jet, creating a down-stream trough off the west-coast.

Studing this associated pair of systems might lead to better modeling of
sub-tropical jets and "standing-wave" patterns.
