If you are someone who wants more or stronger ENSO events in the future, I have great news for you–research supports that. If you are someone who wants fewer or weaker ENSO events in the future, don’t worry–research supports that too.

Forecasters are still calling for a 65% chance of El Nino conditions being met in the next few months. Isn't this late for the start of an ENSO event?

How do changes in the equatorial Pacific Ocean impact places much farther away? The answer for the tropics, at least, lies in changes to the equator-wide atmospheric circulation called the Walker Circulation.

Why hasn't El Niño been declared yet? The answer might lie in the gradients of sea surface temperatures across the tropical Pacific Ocean.

Sea surface temperatures are up. So why haven't forecasters declared El Niño conditions?

One of ENSO’s most important influences is to the Indian Monsoon—the large-scale circulation pattern that brings the Indian subcontinent the vast majority of its yearly rainfall. And while La Niñas tend to increase monsoon rainfall, the monsoon’s relationship with El Niño can be a little more complicated.

How does El Niño affect U.S. winter temperature and precipitation?

ENSO arises from changes across the tropical Pacific Ocean. So why does ENSO affect the climate over sizable portions of the globe, including some regions far removed from the tropical Pacific Ocean?
