The current El Nino has moved into the record books… tying 1997-1998 as the strongest on record.
El Nino is a natural warming of the central tropical Pacific that changes weather patterns worldwide.
Mike Halpert… deputy director of NOAA’s Climate Prediction Center… says data for October/November/December equal the same period in 1997 for the strongest El Nino.
Records date back to 1950.
El Nino is measured based on the warmth over parts of the central Pacific for three consecutive months.
