1. Sea level and sea surface temperature anomalies typical of the El Nino-Southern Oscillation (ENSO) http://www.cdc.noaa.gov/people/joseph.barsugli/anim.html

2. Comparison of the evolution of sea surface temperature anomalies for the last big warm events (1982/83 and 1997/98) http://www.cdc.noaa.gov/map/clim/sst_olr/old_sst/sst_anim_2panel.shtml

3. ENSO Impacts

5. Impacts over the U.S: An example from the 1982/83 warm event DJF 200-hPa Geopotential Heights Note the strengthening of the upper-level ridge off west coast and the deepening of the trough over the southeastern U.S. Normal Conditions 1982/83

6. This pattern was associated with anomalously warm conditions along the west coast and in the far northeast (red shading) and heavier than than normal rains in the southern states (blue shading).
