    Moderate rain describes rainfall with a precipitation rate of between 2.6 millimetres (0.10 in) and 7.6 millimetres (0.30 in) per hour. Heavy rain describes rainfall with a precipitation rate above 7.6 millimetres (0.30 in) per hour, and violent rain has a rate more than 50 millimetres (2.0 in) per hour. [11]

    Precipitation induced by orographic lift in Andalusia. Precipitation induced by orographic lift occurs in many places throughout the world. Examples include: The Mogollon Rim in central Arizona; The western slope of the Sierra Nevada range in California. The western slope of the Wasatch Range in Utah. Specifically the Little and Big Cottonwood ...

    Rain forests are characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1,750 and 2,000 mm (69 and 79 in). [98] A tropical savanna is a grassland biome located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes, with rainfall between 750 and 1,270 mm (30 and 50 in) a year.

  5. Weather front - Wikipedia

    en.wikipedia.org/wiki/Weather_front

    However, precipitation along warm fronts is relatively steady, as in light rain or drizzle. Fog, sometimes extensive and dense, often occurs in pre-warm-frontal areas. [23] Although, not all fronts produce precipitation or even clouds because moisture must be present in the air mass which is being lifted. [1]

  6. Orography - Wikipedia

    en.wikipedia.org/wiki/Orography

    Orographic precipitation is known to occur on oceanic islands, such as the Hawaiian Islands and New Zealand; much of the rainfall received on such islands is on the windward side, and the leeward side tends to be quite dry, almost desert-like. This phenomenon results in substantial local gradients in the amount of average rainfall, with coastal ...

    Frontal cirrostratus is a precursor to rain or snow if it thickens into mid-level altostratus and eventually nimbostratus, as the weather front moves closer to the ...

    Rainfall in these regions averages between 300 and 600 millimeters (11.8 and 23.6 in) per year, with lower amounts across Baja California Norte. Average rainfall totals are between 600 and 1,000 millimeters (23.6 and 39.4 in) in most of the major populated areas of the southern altiplano, including Mexico City and Guadalajara.

  9. Synoptic scale meteorology - Wikipedia

    en.wikipedia.org/wiki/Synoptic_scale_meteorology

    An L represents low pressure, which frequently accompanies precipitation. Various symbols are used not just for frontal zones and other surface boundaries on weather maps, but also to depict the present weather at various locations on the weather map. Areas of precipitation help determine the frontal type and location.
