How does El Niño affect climate?
Winds blow the warm water southward, making coastal Alaska cooler.
Winds blow the warm waters northward, making coastal Alaska warmer.
Warm water move westward, making coastal South America cooler.
Warm waters move eastward, making coastal South America warmer.
The correct answer is Warm waters move eastward, making coastal South America warmer. El Niño is a natural, periodic warming of the central and eastern tropical Pacific Ocean, which affects weather patterns around the world. The warming of the ocean leads to changes in atmospheric circulation, resulting in altered rainfall patterns and temperature extremes in many regions. In particular, El Niño often leads to increased rainfall in parts of South America, as well as warmer temperatures and droughts in some parts of Asia and Australia.

El Niño is a climate phenomenon that occurs in the tropical Pacific Ocean and it has various effects on climate patterns around the world. El Niño refers to the abnormal warming of the sea surface temperatures in the central and eastern tropical Pacific.
During El Niño, the trade winds, which are the prevailing winds blowing from east to west along the equator, weaken or even reverse. This weakening of the trade winds has a significant impact on ocean currents and surface temperatures, leading to a series of climate impacts.
One of the effects of El Niño is that winds blow the warm waters northward, making coastal Alaska warmer. This is due to the change in ocean currents and the redistribution of warm water across the Pacific Ocean. As the trade winds weaken or reverse, warm water that is typically in the western Pacific is transported eastward towards the coast of Alaska, resulting in an increase in sea surface temperatures and warmer weather conditions.
On the other hand, the impact of El Niño on coastal South America is different. During El Niño, the warm waters that are normally in the western Pacific move eastward towards the coast of South America. This results in an increase in sea surface temperatures and makes coastal South America warmer. This warming of the waters can have significant impacts on weather patterns, including changes in rainfall, drought conditions, and even disruptions in marine ecosystems.
Overall, El Niño has wide-ranging effects on global climate patterns, influencing weather conditions and ocean currents in various regions. Understanding these impacts helps scientists and researchers predict and monitor climate variations associated with El Niño events.
