Types Of Rain
Transcript of Types Of Rain
For convectional rainfall to occur the sun first heats the ground and then the warm air rises. As it rises, it cools and water vapour condenses to form clouds. As a result, heavy rainfall falls and it is sometimes accompanied by thunderstorms.
There are various types of rain: conventional rainfall, relief rainfall and frontal rainfall. Frontal rainfall occurs when two masses of air, one cold and the other warm, meet, causing a front. Precipitation eventually occurs and the rain falls over a wide area. It is the most common type of rainfall in the UK; UK receives heavier frontal rainfall compared to convection rainfall.
Relief rainfall refers to rain that falls on the windward side of a mountain. It occurs when wet onshore winds meet a barrier and thus forced to rise where it condenses due to low temperatures eventually falling as rain on the windward side of the slope. It is also referred to as orographic rainfall
Building a rain gauge to measure the amount of rain your area receives in a week is an easy and educational project for children and adults. Rain measurement helps farmers and others make decisions about planting, harvesting, and irrigating crops; it also enables engineers to design effective storm drains, bridges, and other structures. By using a few household items and the steps below, you can make your own gauge to measure the rainfall in your neighborhood.
