Equatorial Pacific Meridional Wind Anomaly Index Since 1850

[ Get Data ]

Abstract: The University of Washington Joint Institute for the Study of the Atmosphere
and Ocean (JISAO) offers an Equatorial Pacific Meridional Wind Anomaly Index
dataset for the years 1850-2005. This is an ENSO meridional wind anomaly index
calculated for the region 12-2N, 160E-70W from the COADS data. This region was
chosen from a map of meridional wind regressed onto an index of eastern
equatorial Pacific SST for the period 1950-79. The anomalies are with respect
to a 1950-79 climatology.
