  2. Precipitation - Wikipedia

    en.wikipedia.org/wiki/Precipitation

    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.

  3. Cloud - Wikipedia

    en.wikipedia.org/wiki/Cloud

    The origin of the term "cloud" can be found in the Old English words clud or clod, meaning a hill or a mass of stone. Around the beginning of the 13th century, the word came to be used as a metaphor for rain clouds, because of the similarity in appearance between a mass of rock and cumulus heap cloud.

  4. Graupel - Wikipedia

    en.wikipedia.org/wiki/Graupel

    Graupel (/ ˈ ɡ r aʊ p əl /; German: [ˈɡʁaʊpl̩] ⓘ), also called soft hail or snow pellets, [1] is precipitation that forms when supercooled water droplets in air are collected and freeze on falling snowflakes, forming 2–5 mm (0.08–0.20 in) balls of crisp, opaque rime. [2] Graupel is distinct from hail and ice pellets in both ...

  5. Earth rainfall climatology - Wikipedia

    en.wikipedia.org/wiki/Earth_rainfall_climatology

    Geographic distribution of rain is largely governed by climate type, topography and habitat humidity. In mountainous areas, heavy precipitation is possible where the upslope flow is maximized within windward sides of the terrain at elevation. On the leeward side of mountains, desert climates can exist due to the dry air caused by compressional ...

  6. Weather - Wikipedia

    en.wikipedia.org/wiki/Weather

    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.

  7. Precipitation types - Wikipedia

    en.wikipedia.org/wiki/Precipitation_types

    Precipitation is measured using a rain gauge, and more recently remote sensing techniques such as a weather radar. When classified according to the rate of precipitation, rain can be divided into categories. Light rain describes rainfall which falls at a rate of between a trace and 2.5 millimetres (0.098 in) per hour. Moderate rain describes ...

  8. Rain of animals - Wikipedia

    en.wikipedia.org/wiki/Rain_of_animals

    A rain of animals is a rare meteorological phenomenon in which flightless animals fall from the sky. Such occurrences have been reported in many countries throughout history, an example being Lluvia de peces , a phenomenon that has occurred many times in Honduras . [ 1 ]

  9. Cloud seeding - Wikipedia

    en.wikipedia.org/wiki/Cloud_seeding

    They believe that it increases the amount of rain over several increasingly arid regions, including its capital city, Beijing, by firing silver iodide rockets into the sky where rain is desired. There is even political strife caused by neighboring regions that accuse each other of "stealing rain" using cloud seeding. [ 46 ]
