In an El Nino year, trade winds are too weak to send warm currents west. Instead, warm currents travel east into South America. What is the end result of this difference in an El Nino year? A. Areas see significant changes in temperature and levels of precipitation. B. Equatorial winds are particularly strong. C. Areas of North America have a colder winter. D. Warm water pools toward the west.

GPT-4o mini · Answer

The end result of the changes in ocean currents and winds during an El Niño year is:

A. Areas see significant changes in temperature and levels of precipitation.

During an El Niño event, the weakening of trade winds allows warm water to move eastward, leading to alterations in weather patterns, including increased rainfall in some areas (like the western coasts of North and South America) and drought conditions in others (like Indonesia and Australia).
