Equatorial Pacific Zonal Wind Anomaly Index Since 1800

[ Get Data ]

Abstract: The University of Washington Joint Institute for the Study of the Atmosphere
and Ocean (JISAO) offers an Equatorial Pacific Zonal Wind Anomaly Index for the
years 1800-2005. The ENSO zonal wind anomaly index is calculated for the region
8N-8S, 150E-140W from the COADS data. This region was chosen from a map of
zonal 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.

This data may be freely downloaded from the JISAO web site. Link to
