What is the difference between El Nino and El Nino Modoki?
El Nino can further be classified into two types— traditional El Nino which is characterized by strong anomalous warming in the eastern equatorial Pacific and the El Nino Modoki that is associated with strong anomalous warming in the central tropical Pacific and cooling in the eastern and western tropical Pacific.
When did La Niña last occur?
Recent years when La Niña Modoki events occurred include 1973–1974, 1975–1976, 1983–1984, 1988–1989, 1998–1999, 2000–2001, 2008–2009, 2010–2011, and 2016–2017. The recent discovery of ENSO Modoki has some scientists believing it to be linked to global warming.
What is El Nino effect?
El Nino is a climate pattern that describes the unusual warming of surface waters in the eastern Pacific Ocean. El Niño has an impact on ocean temperatures, the speed and strength of ocean currents, the health of coastal fisheries, and local weather from Australia to South America and beyond. …
What is La Niña phenomenon?
La Nina. La Niña is a climate pattern that describes the cooling of surface ocean waters along the tropical west coast of South America. La Nina is considered to be the counterpart to El Nino, which is characterized by unusually warm ocean temperatures in the equatorial region of the Pacific Ocean.
Why is La Niña bad?
“La Niña can contribute to an increase in Atlantic hurricane activity by weakening the wind shear over the Caribbean Sea and tropical Atlantic Basin, which enables storms to develop and intensify,” Halpert said in 2020.
How many years does La Niña last?
Although La Niña can sometimes persist for two years, seasonal forecasting agencies, such as the Bureau of Meteorology, are predicting neutral conditions for the rest of the year and next summer. The strong La Niña event of 2010/2011 resulted in massive floods in Queensland.
When did the Modoki version of El Nino develop?
Modoki El Niños may have been around going back to the 13th century, possibly before. The El Niño which developed in 2015 is a Modoki version of the phenomenon. Thanks for contributing an answer to Earth Science Stack Exchange!
Where did the term Modoki come from in meteorology?
(The word Modoki was introduced by T. Yamagata during 2004 while explaining a probable cause behind the abnormal summer climatic conditions over Japan. It has been often used since then by various Japanese Mass Media. “Modoki” is a classical Japanese word which means “similar but different.”
Why is Modoki condition increasing in central Pacific?
Yeh et al.3 argue that the increasing frequency of the Modoki condition is due to anthropogenic warming, and that these events in the central Pacific will occur more frequently if global warming increases.
