Scientists said it is likely that the record-breaking El Nino has been bolstered by climate change.
This year’s El Nino is larger than the 1997-98 record event, NASA said.
“El Nino 2015 has already created weather chaos around the world,” NASA said.
“Over the next few months, forecasters expect the United States to feel its impacts as well.”A comparison between satellite images of the Pacific sea surface shows the classic pattern of a fully developed El Niño.
“The images show nearly identical, unusually high sea surface heights along the equator in the central and eastern Pacific: the signature of a big and powerful El Niño. Higher-than-normal sea surface heights are an indication that a thick layer of warm water is present,” Alan Buis writes in a post published on NASA’s website.
“El Ninos are triggered when the steady, westward-blowing trade winds in the Pacific weaken or even reverse direction, triggering a dramatic warming of the upper ocean in the central and eastern tropical Pacific.
