El Nino phenomena occurs after every 3-7 years(Barnabe and Regine,2000 p 30 ) and the surface temperatures in the western and eastern equatorial pacific ocean usually drops by I° c and rise by either 2 or 3° c. During the El Nino events in 1997-98,the sea surface temperatures in the eastern equatorial pacific increased by 5-6° c ,thus creating a uniform surface temperature in the regions lying along the equator and the entire band with of the pacific, that forms nearly the a half of the circumference of the earth. The El Nino phenomena are at its climax in the months of December. ...
