    The exterior of a tipping bucket rain gauge The interior of a tipping bucket rain gauge. The tipping bucket rain gauge consists of a funnel that collects and channels the precipitation into a small seesaw-like container. After a pre-set amount of precipitation falls, the lever tips, dumping the collected water and sending an electrical signal.

    Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind direction; Wind vane (also called a weather vane or a weathercock) for showing the wind direction; Present Weather/Precipitation Identification Sensor for identifying falling precipitation; Disdrometer for measuring drop ...

  4. 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 ...

    The letters in the top row stand for months: January, February, etc. The bars and numbers convey the following information: The blue bars represent the average amount of precipitation (rain, snow etc.) that falls in each month. The blue numbers are the amount of precipitation in either millimeters (liters per square meter) or inches.

    Ascent rate times ascent time yields the ceiling height. A disdrometer is an instrument used to measure the drop size distribution and velocity of falling hydrometeors. Rain gauges are used to measure the precipitation which falls at any point on the Earth's landmass.

    Precipitation [1]; Rain gauge – rainfall depth (unit) and intensity (unit time −1); Disdrometer – raindrop size, total precipitation depth and intensity; Doppler weather radar – raindrop size, total precipitation depth and intensity, rain cloud reflectivity converted to precipitation intensity through calibration to rain gauges

    en.wikipedia.org/wiki/Precipitation_gauge

    The term "Precipitation gauge" may refer to: Disdrometer, an instrument used to measure the drop size distribution and velocity of falling hydrometeors; Rain gauge, also known as an udometer, a pluviometer, an ombrometer or a cup is a type of instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over a set period of time

  9. Pan evaporation - Wikipedia

    en.wikipedia.org/wiki/Pan_evaporation

    Pan evaporation is a measurement that combines or integrates the effects of several climate elements: temperature, humidity, rain fall, drought dispersion, solar radiation, and wind. Evaporation is greatest on hot, windy, dry, sunny days; and is greatly reduced when clouds block the sun and when air is cool, calm, and humid. [ 1 ]
