Heavy rainfall refers to a significant amount of precipitation that falls in a short period, often leading to water accumulation on the ground. It is typically measured in millimeters or inches and can result from various weather systems, including storms and tropical systems. Heavy rainfall can cause flooding, soil erosion, and other environmental impacts. In many regions, heavy rainfall is a crucial part of the water cycle, replenishing rivers, lakes, and groundwater supplies. However, excessive rainfall can disrupt daily life, damage infrastructure, and pose risks to safety. Understanding heavy rainfall patterns is essential for effective flood management and disaster preparedness.
