No sustained negative AO, been stormy at the pole. No blocking.
Haven't had a negative AO since the end of Dec. Models were always wrong in the long range, seasonal models weren't bad as they indicated that would happen.
After a long sustained -AO for months before winter, it had to flip back to balance out.
The EPO wasn't able to sustain itself either.
End result. Fast moving zonal systems with mostly Pacific air.
