On the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating. Most precipitation occurs within the tropics and is caused by convection. [3] Precipitation is a major component of the water cycle, and is responsible for depositing most of the fresh water on the planet.
For the first time, precipitation and the clouds from which precipitation fell were called meteors, which originate from the Greek word meteoros, meaning 'high in the sky'. From that word came the modern term meteorology , the study of clouds and weather.
Typical precipitation types associated with a warm front advancing over frigid air Precipitation in the form of a sunshower. In meteorology, the different types of precipitation often include the character, formation, or phase of the precipitation which is falling to ground level. There are three distinct ways that precipitation can occur.
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
Drizzle is a light precipitation which consists of liquid water drops that are smaller than those of rain – generally smaller than 0.5 mm (0.02 in) in diameter. [1] Drizzle is normally produced by low stratiform clouds and stratocumulus clouds. Precipitation rates from drizzle are on the order of a millimetre (0.04 in) per day or less at the ...
Extraterrestrial "snow" includes water-based precipitation, but also precipitation of other compounds prevalent on other planets and moons in the Solar System. Examples are: Examples are: On Mars , observations of the Phoenix Mars lander revealed that water-based snow crystals occur at high latitudes. [ 107 ]
On July 29, 2010, a record breaking 280 millimetres (11 in) of rain was recorded in Risalpur in 24 hours. [38] On July 29, 2010, a record breaking 274 millimetres (10.8 in) of rain was recorded in Peshawar in 24 hours. [38] On August 9, 2011 176 millimetres (6.9 in) of rainfall was recorded in 3 hours in Islamabad flooded main streets. [39]
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. [1] On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, [2] [3] just below the stratosphere.
