Sea Surface Temperature Anomaly Plot from 1950 to 2015

Sea surface temperature anomalies (SSTA) from NOAA are used to determine when El Nino and La Nina conditions have occurred. This visualization shows a plot over time of SSTAs over a region of the Pacific Ocean called "Oceanic Nino Index Region 3.4". An El Nino happens when the SSTA is greater than 0.5 degrees C (shown in red); a La Nina happens when SSTA is less than -0.5 degrees C (shown in blue).

Over this period, several El Nino events occurred including: 1957-1958, 1972-1973, 1982-1983, and 1997-1998.

This visualization is based on the following NOAA data:
