Although the cesnrs r€sponse to the decrease in the equatorial winds is well-knownt
the reasons for this change in wind petterns is tnknown. This question will have to be
answered if a forecest of El Nino is to be rnade several rmnlhs in advance. TNs will require
further obsarvation of the ocean-atmosphere system and the mechanisms which govern it.
Research progremrnes efe now being set up at the national and international levels for this
pur?ose. The results of this effort will provide us with a better understanding of the
npchanism which causes the decrease in the equatorial winds.
