El Nino Has Significantly Changed In Recent Years, A New Groundbreaking Study Revealed

New research suggests that El Nino has changed in recent years, and different versions of the phenomenon have been spotted.
A new type of El Niño has been observed in recent decades to appear more often in comparison to previous incarnations of the phenomenon which were observed over 400 years. Within the same timeframe, the event has become more aggressive.

Select climate models inferred that the altered El Nino might have caused by climate change, but the amount of reliable information was limited. A new paper aims to address this issue by constructing a map of all the El Nino events observed in the last four centuries. El Nino is a term used to describe a year-long cycle during which the surface waters found in the tropical region of the Pacific are warming. The consequences of this phenomenon are quite severe, and they can be felt across the globe.

El Nino has changed a lot in recent years, according to new research

When El Nino events are intense, some areas of the world, among which we can count Australia and select Asian regions, will receive a lower amount of rainfall. The situation is quite different in the western areas of the two American continents, were abundant precipitations will often tend to lead to massive floods. It is also interesting that many of the hottest periods appear to be in synchronized with the primary.

These problems stem from the fact that the phenomenon can exert visible influence on atmospheric circulation. Usually, a circulation cell known as the Walker circulation will move air.

The new type of El Nino has been tracked in the central Pacific where warm ocean temperatures were detected. While it may not be as sturdy as another version, this localized version of the phenomenon has often been resurfacing in the last years. It is likely that some of these recent events triggered some of the disease outbreaks which are present around the world. The study was published in a peer-reviewed journal.
