High rainfall refers to a significant amount of precipitation that falls in a specific area over a certain period. It is typically measured in millimeters or inches and can lead to various environmental effects, such as increased river flow and soil saturation. Regions that experience high rainfall often have lush vegetation and diverse ecosystems. Areas with high rainfall are commonly found in tropical climates, where warm air holds more moisture. This phenomenon can also occur in temperate zones during specific seasons. Excessive rainfall can lead to flooding, impacting infrastructure and communities, while also replenishing water supplies in drought-prone regions.
