El Niño has become especially powerful this year, with "super El Niño" conditions now officially taking shape.

The National Oceanic and Atmospheric Administration's Climate Prediction Center announced Thursday that the phenomenon, which affects weather and climate around the world, has intensified and continues to strengthen. Its effects through next spring may even be considered historic, the agency said.

Here's everything to know about El Niño:

El Niño is a climate pattern defined by warming waters in a specific region of the Pacific Ocean near the equator. It occurs every two to seven years and usually lasts between nine and 12 months.

When El Niño is active, a large portion of the world gets warmer, too. In September, researchers at the University of Chicago predicted that an estimated 451,000 more people would die worldwide during this year's El Niño, compared with a typical year, because of excessive heat exposure.

The impacts of El Niño vary in different parts of the world, adjusting hurricane frequencies, altering sea levels, and at times triggering mass flooding or severe drought as well as seasonal snowfall amounts that depart from historical averages.
