El Niño Southern Oscillation (ENSO)
ENSO's Effects on Global Temperature and Precipitation
Select temperature or precipitation composite based on season and phase of ENSO:
Temperature and precipitation anomalies have been composited for El Niño and La Niña years (from Kiladis and Diaz). Composites were done for overlapping seasons from the year preceding a peak event to the year following the peak event. The dataset used was the GHCN dataset available at NCDC (1857-1994). Anomalies were computed by removing the monthly means from 1951 to 1980 but were not standardized. Units are millimeters/month for precipitation and degrees for temperature Image/Product provided by the NOAA/ESRL Physical Sciences Division, Boulder Colorado from their web site at http://www.esrl.noaa.gov/psd/.
