About every 4 years, faltering easterly trade winds over the tropical Pacific Ocean cause warm waters to linger, generating an anomalously warm wet period in the eastern Pacific for about 6 months. During these times, the western Pacific becomes cooler and drier. A few years later, a reversal of these conditions occurs when trade winds amplify, pushing warm waters even farther west, leading to unusually cool waters across a broad expanse of the equatorial Pacific.
