Final answer:
El Niño is a climate pattern characterized by changing wind patterns that reverse oceanic currents near the equator, leading to shifts in weather patterns worldwide.
Step-by-step explanation:
El Niño is a climate pattern characterized by the changing wind patterns that reverse oceanic currents near the equator. During El Niño, warm ocean currents flow eastward along the equator, causing shifts in weather patterns worldwide. This phenomenon typically leads to increased rainfall in areas such as the western coast of South America and can have significant impacts on global weather patterns.
