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.
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.
Effect of a rain shadow The Tibetan Plateau (center), perhaps the best example of a rain shadow. Rainfalls from the southern South Asian monsoon do not make it far past the Himalayas (seen by the snow line at the bottom), leading to an arid climate on the leeward (north) side of the mountain range and the desertification of the Tarim Basin (top).
Precipitation is very irregular in tropical deserts. The average annual precipitation in low latitude deserts is less than 250 mm. Relative humidity is very low – only 10% to 30% in interior locations, and even the dewpoints are typically very low, often being well below the freezing mark. Some deserts do not have rainfall all year round ...
Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.
Drylands are zones where precipitation is balanced by evaporation from surfaces and by transpiration by plants (evapotranspiration). [1] The United Nations Environment Program defines drylands as tropical and temperate areas with an aridity index of less than 0.65. [2] One can classify drylands into four sub-types: Dry sub-humid lands; Semi ...
For example, Burlington, Vermont has a summer maximum and a winter minimum. In contrast, Portland, Maine has a fall and winter maximum, with a summer minimum in precipitation. [61] Temporally, a maximum in precipitation is seen around three peak times: 3 a.m., 10 a.m., and 6 p.m. During the summer, the 6 p.m. peak is most pronounced. [62]
A rain of fish was recorded in Singapore in 1861, when during three days of torrential rain numerous fish were found in puddles. Raining snakes, 1680. A rain of animals is a rare meteorological phenomenon in which flightless animals fall from the sky.
