Rainfall is the result of water vapor condensing and precipitating, forming droplets that fall from clouds due to gravity. It is an important part of the water cycle.Know More
Condensation occurs when the air cools and becomes saturated. Clouds form when water condenses on particles in the air. The air can be cooled in several ways. Adiabatic cooling is caused by rising and expanding air. Conductive cooling occurs when air is affected by a colder surface. Radiative cooling is caused by infrared radiation, and evaporative cooling occurs when the air is saturated due to evaporation.
All of these forms of cooling can lead to the saturation of the air, condensation and precipitation. These processes may lead to the formation of clouds and water droplets, which leave the air as rainfall.Learn more about Rain
The Arab Republic of Egypt receives an average of 2 inches of rain a year. The amount of rain varies by region: the area along the Mediterranean Sea gets about 8 inches a year, while in the rest of the country, rain is very scarce.Full Answer >
A convectional rainfall diagram gives a visual representation of the process through which atmosphere produces convectional rain. The diagram starts with warming land, which heats the air above it and causes the air to expand and rise. Clouds form and rain falls as the air condenses and cools.Full Answer >
The country with the highest rainfall worldwide is the South American nation of Colombia. Based on yearly average precipitation measurements collected between 2010 and 2014, Colombia received an average annual rainfall of 127.6 inches as reported by the World Bank Group. The African nation of Sao Tome and Principe is a close second with average annual rainfalls during the same time period reported as 126 inches.Full Answer >
The average rainfall in the Amazon rainforest is about 108 inches per year. The high amount of rain combined with a warm year-round climate makes the Amazon rainforest the most biodiverse place on Earth.Full Answer >
