What is the Niño 4 index?
This is the operational definition used by NOAA. Niño 4 (5N-5S, 160E-150W): The Niño 4 index captures SST anomalies in the central equatorial Pacific. This region tends to have less variance than the other Niño regions.
How are El Niño and La Niña anomalies calculated?
Usually the anomalies are computed relative to a base period of 30 years. The Niño 3.4 index and the Oceanic Niño Index (ONI) are the most commonly used indices to define El Niño and La Niña events. Other indices are used to help characterize the unique nature of each event.
What are the different Nino SST indices?
Nino SST Indices (Nino 1+2, 3, 3.4, 4; ONI and TNI) Niño 1+2 (0-10S, 90W-80W): The Niño 1+2 region is the smallest and eastern-most of the Niño SST regions, and corresponds with the region of coastal South America where El Niño was first recognized by the local populations. This index tends to have the largest variance of the Niño SST indices.

What is the niniño 1+2 region?
Niño 1+2 (0-10S, 90W-80W): The Niño 1+2 region is the smallest and eastern-most of the Niño SST regions, and corresponds with the region of coastal South America where El Niño was first recognized by the local populations. This index tends to have the largest variance of the Niño SST indices.
How does El Nino affect human communities?
Ecosystems and human communities can be positively or negatively affected. For example, in the Southern United States, during the fall through spring, El Niño usually causes increased rainfall and sometimes destructive flooding.
When does El Niño become full-fledged?
More… onset of El Niño declared when Niño 3.4 anomaly exceeds +0.5°C for 3-month period to be “full-fledged” El Niño (or La Niña), onset conditions must be met for 5 consecutive 3-month periods
