El Nino shifts weather across the Pacific

Weakened trade winds leave warm water spread east and disrupt rainfall In a normal year trade winds pile warm surface water in the western Pacific. During El Nino those winds slacken, warm water spreads eastward and rainfall follows it. The pattern repeats every two to seven years and can bring drought to Australia and floods to Peru. It sits in Mondo's science collection, one of 200 facts that each trace back to the reference below.
