Can we keep this one going for at least a week? Western ridging has consistently underperformed w/rt long range model projections this year, but this is the most favorable large scale forcing structure for a +TNH response in quite awhile. And you’d also expect at least some +TNH in a canonical post-niño environment (we’ve had almost none this year so far).
Come mid-June, subsidence returns to the IPWP/WPAC, so it ain’t gonna stick around. But it’ll be interesting to see how long it can hold on.
At long last, the majority of guidance projects a clean mid-latitude response to WPAC MJO forcing (+TNH). Very delayed but not denied.
Note how the projected height anomalies are fairly similar to map of correlations to heat content within the pacific warm east of the dateline (WHWP).
