El Nino is a climate phenomenon that occurs in the Pacific Ocean. It refers to the abnormal warming of sea surface temperatures in the central and eastern equatorial Pacific, which has significant impacts on global weather patterns. During a typical El Nino event, the trade winds that blow from east to west across the Pacific weaken or reverse. This weakens the upwelling of cold, nutrient-rich water in the eastern Pacific, leading to warmer surface temperatures. As a result, the atmospheric circulation patterns change, influencing weather conditions around the world. The impacts of El Nino can vary depending on its intensity and duration. Some common effects include: 1. Changes in rainfall patterns: El Niño can lead to increased rainfall in the central and eastern Pacific, including regions like Peru and Ecuador. Conversely, it can cause reduced rainfall in Southeast Asia and parts of Australia. 2. Temperature anomalies: El Niño often brings warmer temperatures to the eastern Pacific a...
