Further studies of temporal coherence in North Pacific Sea surface temperatures

Temporal coherence between monthly mean space-averaged sea surface temperature anomalies over the North Pacific is appreciably greater than pattern coherence, and thus some conservatism of anomalies as they are redistributed by the North Pacific Ocean gyres is indicated. When they are stratified by initial month, autocorrelations show strong recurrence from one nonsummer month to subsequent months out to 2 years except for summer. The autocorrelations drop between May and June and rise between September and October, changes which appear to be related to wind strength and wind mixing in the oceanic surface layers.
