Precipitation, or rain, is defined in meteorology as any form of water, liquid or solid, that falls from clouds. It is measured by the amount of rain water or snow collected in a cylinder-shaped plastic or metal rain gauge over a period of time. The highest recorded 12-month rainfall of 905 inches was measured in the village of Cherrapunji in Northeastern India in 1861. The town of Lloro, in Choco, Colombia, is a contender for the place with the highest rainfall on Earth because of its average annual rainfalls of about 520 inches.
