Final answer:
El Niño is a weather phenomenon in the Pacific Ocean that affects global weather. It causes increased rainfall and alters wind patterns.
Step-by-step explanation:
El Niño is a climate pattern that occurs in the Pacific Ocean, affecting weather conditions worldwide. It is caused by the warming of the South Pacific Ocean and can last for several months to a few years.
Two ways in which El Niño changes the weather of a region are:
- Increased Rainfall: El Niño can cause increased rainfall in some regions, leading to floods and landslides. For example, it can bring heavy rainfall to the western coast of South America.
- Altered Wind Patterns: El Niño can cause changes in wind patterns, affecting global weather systems. For instance, it can weaken trade winds in the Pacific, leading to reduced upwelling and potentially impacting fisheries.
