A rainstorm is a weather event characterized by the falling of water droplets from clouds. It occurs when moisture in the atmosphere condenses and becomes heavy enough to fall to the ground. Rainstorms can vary in intensity, from light drizzles to heavy downpours, and they often bring cooler temperatures and increased humidity. Rainstorms can also be accompanied by other weather phenomena, such as thunder and lightning. These storms play a crucial role in the water cycle, replenishing groundwater and providing essential moisture for plants and ecosystems. They can also lead to flooding if the rainfall is excessive or prolonged.
