The team examined details of 33 El Niño events from 1901 to 2017, evaluating for each event the onset location of the warming, its evolution, and its ultimate strength. Foster also confirmed El Nino conditions threaten to make tropical cyclones more prevalent during hurricane season, which spans the months of June to November. Climate warming promises more frequent extreme El Niño events. They also found that four of five identified extreme El Niño events formed after 1970. Wang and his co-authors focused on the factors that seemed to be controlling these shifts, including increased sea surface temperatures in the western Pacific warm pool and the easterly winds in the central Pacific, and found that with continued global warming, those factors may lead to a continued increase in frequency in extreme El Niño events. El Niño events cause serious shifts in weather patterns across the globe, and an important question that scientists have sought to answer is: how will climate change affect the generation of strong El Niño events?

El Niño is a … The classification system derived in this study provides an important tool for improvement in climate modeling of El Niño and La Niña events. “December was still neutral conditions,” Foster said, “(But) it would be expected drier than normal over the next few months.”. Following a four-year bleaching period between 2014-17, last year saw West Hawaii come under a coral reef bleaching watch as waters approached threshold temperatures and held elevated temperatures for a duration of several weeks.

El Nino was only one of several factors, both natural and human-driven, that led to the extreme bleaching event of 2015. University of Hawaii at Manoa.

This is the weakened Walker Circulation pattern, due to more rising air than average over the central Pacific as the warmth of the ocean is transferred to the air above.

Because of this, and despite rainfall through last summer and fall that left green grass crop in several areas across the state, large fire potential is expected to increase to above normal levels from January to March.
