El Niño, a natural climate pattern, occurs when ocean surface temperatures in the central and eastern Pacific Ocean rise above normal. This phenomenon can influence weather patterns worldwide, but it does not guarantee heavy rainfall in all regions. The article explains that El Niño's effects vary depending on location and other climatic factors. In some areas, it may lead to droughts, while in others, it could bring increased precipitation. Understanding these variations is crucial for predicting and preparing for climate-related impacts. The explanation highlights the complexity of weather systems and the need for accurate forecasting.
