Summarizes the findings to date, and places them in a regional and historical context. Discusses the SEAFRAME gauge in Manus Island, Papua New Guinea, which records sea level, air and water temperature, atmospheric pressure, wind speed and direction. It is one of an array designed to monitor changes in sea level and climate in the Pacific.
This paper addresses the question of whether the increased occurrence of central Pacific (CP) versus Eastern
Pacific (EP) El Niños is consistent with greenhouse gas forced changes in the background state of the tropical Pacific as inferred from global climate change models.
The analysis uses high‐quality satellite and in situ ocean data combined with wind data from atmospheric reanalyses for the past 31 years (1980–2010).
