Ocean currents, particularly during El Niño and La Niña events, influence global climate patterns. El Niño, characterized by warmer-than-average sea surface temperatures in the central and eastern Pacific, can lead to increased rainfall in some regions and drought in others, impacting weather patterns globally. Conversely, La Niña, marked by cooler-than-average sea surface temperatures, can result in the opposite effects, influencing precipitation and temperature patterns across different regions.
