Guest post by Paul Vaughan, M.Sc.
Awhile back I drew attention to temporal patterns shared by the <i>rate of change</i> of solar cycle length (SCL’) and the Atlantic Multidecadal Oscillation (AMO). (See here.)
Correspondence I received later alerted me to the existence of fairly widespread misunderstandings about fundamental differences between the following:
a) Pacific Decadal Oscillation (PDO).
b) North Pacific SST (SST = Sea Surface Temperature).
Some folks, thinking of the PDO, seemed troubled by a <b>mis</b>perception that the Atlantic tracks SCL’ <i>much</i> better than the larger Pacific.
Supplementary graphs may help motivate efforts to overcome misunderstandings:
