Ocean and air temperatures around the world reached record-high levels last year, and they’ve both remained exceptionally warm throughout most of 2024. Some of the historic warming we saw in ...

The ENSO cycle loosely operates over timescales from one to eight years. An El Niño occurs when sea surface temperatures in the central and eastern tropical Pacific Ocean become substantially warmer ...

The 2015–16 El Niño has likely reached its end. Tropical Pacific Ocean temperatures, trade winds, cloud and pressure patterns have all dropped back to near normal, although clearly the event's impacts ...

Satellite imagery can help determine the strength, size and cohesion of a storm. The stronger a storm becomes, the more ...

A strong El Niño ended this past spring and we’re on the path to a weak La Niña in time for this winter. These patterns of above- and below-seasonal ocean temperatures in the eastern Pacific ...

It affects weather worldwide. El Niño is a natural climate pattern in which surface sea water temperatures in the central and eastern tropical Pacific Ocean are warmer than average. Whether the ...

A new modeling study shows that the El Nino event, a huge blob of warm ocean water in the tropical Pacific Ocean that can change rainfall patterns around the globe, was present at least 250 ...

For the Southeast, El Niño cycles are associated with fewer hurricanes in the Atlantic Ocean, more rainfall and higher flood risks. During La Niña events, trade winds pick up and become ...

The El Niño event, a huge blob of warm ocean water in the tropical Pacific Ocean that can change rainfall patterns around the globe, isn't just a modern phenomenon. A new modeling study from a ...

El Niño, the climate phenomenon associated with a massive warm water patch in the Pacific Ocean that disrupts global weather patterns, isn’t a purely modern occurrence. A new study led by Duke ...
