El Nino and La Nina
El Niño and La Niña are parts of an oscillation in the ocean-atmosphere system (called the El Niño Southern Oscillation, or ENSO cycle) that can impact weather and climate conditions across the globe. El Niño features warmer-than-average temperatures in the waters of the equatorial Pacific Ocean, while La Niña features colder-than-average waters. Read our stories below on the latest ENSO conditions and research into how the cycle affects global weather patterns.
