Final answer:

Large El Niño events affect ocean conditions by bringing warm water to the eastern Pacific, disrupting upwellings, and influencing global weather patterns.


Explanation:

During large El Niño events, warm water from the western equatorial Pacific moves to the eastern equatorial Pacific, causing the eastern Pacific Ocean to become warmer than usual. This warm water moving eastward prevents cold-water upwellings along the western coast of South America by deepening the thermocline.

The changes in water temperature, winds, and currents during El Niño affect climates worldwide. This can lead to heavier rainfall in some areas and drought conditions in others, impacting global weather patterns.

The high pressure system over the eastern Pacific diminishes during El Niño, weakening trade winds and causing warm surface water to flow eastward across the Pacific. This influx of warm water prevents upwelling along the western coast of South America, impacting marine life and productivity.
