Easterly trade winds from near-equatorial islands in the central Pacific weakened before each El Ni�o between 1950 and 1978, except for the 1963 El Ni�o. The weakening of the easterlies and their later collapse did not occur uniformly over several months, but rather through a series of strong westerly wind bursts lasting 1 to 3 weeks. The bursts may force equatorial Kelvin waves in the ocean that can both initiate and sustain the sea surface warming characteristics of El Ni�o events.
