Paleoclimatic aspects of El Niño/Southern Oscillation

Authors


Abstract

A workshop on paleoclimatic aspects of the El Niño/Southern Oscillation (ENSO) phenomenon was held May 2–4 in Boulder, Colo. Sponsored by the National Geophysical Data Center of the National Oceanic and Atmospheric Administration, goals of the workshop were to review the state of knowledge of the ENSO phenomenon based on instrumental and historical records and modeling experiments; to review paleoclimatic proxy evidence from records of tree rings, sea corals, tropical glacier ice cores, and fluvial and lacustrine sediment sequences from North and South America, Australasia and the equatorial Pacific for their sensitivity to ENSO, and to assess their potential for reconstructing past ENSO variability; to explore ways to integrate different aspects of ENSO paleoclimatic information with contemporary observations and numerical models of ENSO; and to identify strategies and goals for future interaction and collaboration between climatologists and paleoclimate researchers working on ENSOsensitive proxy records.
