During late June/early July, emergence of a strong positive phase global atmospheric angular momentum (++GLAAM) regime has returned. The new surge of +GLAAM is related to the onset of an El Nino climate. Previously, a pulse of ++GLAAM was observed during late May/early June, elated to a strong Madden Julian oscillation (MJO) episode, and the correlating U.S. temperature anomalies were extremely warm, especially for the Central U.S.

The North Atlantic warm hole (NAWH) is intensifying, one of the most impressive early July signatures on record. The cold SSTA east of Newfoundland coupled with warm SSTA to the south inspire stronger than normal westerly wind compensated for by stronger easterly trade winds to the south of The Bermuda High.

Upper ocean heat observations for June 2026 reveal record warmth in the equatorial Pacific region with waters east of the Dateline getting close to the record observed during the all-time strongest El Nino in 1997. Fuel to accelerate El Nino 2026-27 to record levels is clearly present.

Upper ocean heat has reached a second peak and will approach the all-time record in July previously produced during the 1997 El Nino. The reaction is oceanic El Nino warming reaching strong intensity with atmospheric El Nino (also) intensifying rapidly.
