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 ...
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 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
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 ]
The Plain English Campaign objected to the Met Office's use of the phrase "probability of precipitation" in 2011. [ 14 ] [ 15 ] The Met Office explained that the proposed alternative, "chance of rain", would not describe all the forms of precipitation included in the forecast.
The raindrop size distribution (DSD), or granulometry of rain, is the distribution of the number of raindrops according to their diameter (D). Three processes account for the formation of drops: water vapor condensation, accumulation of small drops on large drops and collisions between sizes.
Gauge and gage are often used as alternative spellings. To the extent that there is a difference, a weather gauge can be a form of meteorological instrumentation for measuring weather quantitatively, such as a rain gauge, thermometer, anemometer, or barometer.
