Scientists from the National Oceanic and Atmospheric Administration (NOAA) along with its partners are working across land… air and sea platforms in the tropical Pacific to study like never before El Niño… in hopes of improving short and long term weather forecasts.

Scientists will be collecting important data from the large expanse of ocean in the tropical Pacific where El Niño-driven weather systems develop.

This has never been done with a major El Niño before.

El Niño happens in a regular pattern… and is characterized by unusually warm ocean temperatures in the equatorial Pacific. El Niño is the warm phase of the what is called the El Niño-Southern Oscillation… or ENSO for short.

La Niña is the cool phase. The pattern can shift back and forth every two to seven years… disrupting weather patterns across the globe.
