Résumé
"The effects of El Niño Southern Oscillation 1997-1998 on the Eastern Tropical Pacific Ocean are evaluated for the Tehuantepec (Mexico) and Papagayo (Costa Rica) upwelling regions. The influence of this phenomenon was observed by comparing sea surface temperature anomalies over a 3-year period, from winter 1996-1997 to winter 1999-2000. Satellite observations reveal an increment of 3 and 4ºC during the El Niño year 1997- 1998 compared with previous and subsequent years, and the inhibition of upwelling events. It was also observed that during ‘La Niña’, winter 1998-1999, conditions for upwelling events were re-established."
