Subsurface Moderately Cold in Equatorial East Pacific as La Nina Likely to Linger well into NH Spring

Since 1979 the subsurface equatorial Pacific Ocean to the east of the Dateline has produced peak subsurface cool signatures during La Nina, most dramatically during late last century with more frequent but less intense peak subsurface cool signatures during La Nina in this century. The JAN-25 subsurface cool anomaly was -1.32 and the coolest monthly signature from the 2024-25 cold ENSO episode.

Taking over! The West/Central North Pacific Marine Heat Wave!

During the current decade, a marine heat wave (MHW) east of Asia has steadily intensified and become the most dominant regional SSTA influence on northern hemisphere climate. During the second half of the previous decade, the Northeast Pacific MHW and North Atlantic warm hole (NAWH) were influential on the northern hemisphere climate pattern. Added during the past 12-18 months is a persistent MHW west and southwest of Europe.
