PRECIPITATION

Precipitation is moisture that falls from the atmosphere as rain, snow, sleet, or hail. Precipitation varies in amount, intensity, and form by season and geographic location. These factors impact whether water will flow into streams or infiltrate into the ground. In most parts of the world, records are kept of snow and rainfall. This allows scientists to determine average rainfalls for a location as well as classify rainstorms based on duration, intensity and average return period. This information is crucial for crop management as well as the engineering design of water control structures and flood control.
