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 warm water pools toward the rest
c equatorial winds are particularly strong
d areas of north america have a colder winter

The correct answer is:

a) Areas see significant changes in temperature and levels of precipitation.

During an El Niño year, the weakening of trade winds prevents the warm currents from traveling westward and instead pushes them eastward into South America. This results in significant changes in temperature and precipitation patterns in various regions across the globe. Some areas experience warmer temperatures and increased rainfall, while others may have drier conditions than usual. Therefore, the end result of this difference in an El Niño year is that areas see significant changes in temperature and levels of precipitation.
