15Summary of Normal Conditions Warm, wet weather in western Pacific (Indonesia)Cooler, dry weather in eastern Pacific (Peru)Upwelling causes good fishing off the coast of Peru
16El Niño Conditions Winds blowing from east to west become weaker Less water moves from east to west (sometimes moves from west to east!)More warm water in the Eastern Pacific
17El Niño Conditions More warm water in the Eastern Pacific causes A. Less upwellingB. Less fishingC. Changes in weather in the Eastern and Western PacificD. All of the above!
18El Niño Conditions More warm water in the Eastern Pacific causes A. Less upwellingB. Less fishingC. Changes in weather in the Eastern and Western PacificD. All of the above!
