What are the forms of precipitation? In the weather forecast, precipitation is divided into

Precipitation is the phenomenon that water in the cloud falls to the ground in liquid or solid form. It includes rain, snow, sleet, rice snow, frost, hail, ice particles and ice needles.

According to different physical characteristics, precipitation can be divided into liquid precipitation and solid precipitation. Liquid precipitation includes rain, rainstorm, thunderstorm, freezing rain and shower in Mao Mao, solid precipitation includes snow, hail and graupel, and liquid-solid mixed precipitation, such as sleet.

Meteorology uses precipitation to distinguish the intensity of precipitation, which is divided into: light rain, moderate rain, heavy rain, heavy rain, heavy rain, heavy rain, light snow, medium snow, heavy snow and blizzard.

Light rain: raindrops are clearly visible without floating; The ground does not splash; The water in the depression is very slow; The rain on the house is weak, and there is only dripping water on the eaves; 12 hour precipitation is less than 5mm or 24 hour precipitation is less than10mm.

Moderate rain: the rain falls like a line, and the raindrops are not easy to distinguish; Fall heavily and splash; Water accumulated in depression is faster; There is rustling rain on the roof; 12 hour precipitation 5 ~10 ~ 25mm or 24 hour precipitation10 ~ 25mm.

Heavy rain: the rain falls like a downpour, blurred into pieces; The water in the depression is extremely fast; There is rain on the roof; 12 hour precipitation15 ~ 30mm or 25 ~ 50mm 24 hour precipitation.

Rainstorm: Any rainfall process with precipitation exceeding 50 mm within 24 hours is collectively referred to as rainstorm. According to the intensity of rainstorm, it can be divided into: rainstorm, heavy rainstorm, and there are three kinds of rainstorm. Rainstorm: a rainfall process in which the precipitation is 30 ~ 70 mm in 12 hour or 50 ~ 100 ~ 250 mm in 24 hours. Rainstorm: the rainfall process with precipitation of 70 ~140mm within 2 hours or 0/00 ~ 250mm within 24 hours.

Light snow: the snowfall process in which the snowfall is less than10.0 mm within 12 hours (equivalent to melting rainfall, the same below) or less than 2.5mm within 24 hours.

Snowfall: 12 hour snowfall1.0 ~ 3.0mm, or 24-hour snowfall of 2.5 ~ 5.0mm or snow depth of 3cm.

Heavy snow: 12 hour snowfall of 3.0 ~ 6.0mm or 24-hour snowfall of 5.0 ~10.0mm or snowfall with snow depth of 5cm.

Blizzard: A snowfall process in which 12 hour snowfall is greater than 6.0 mm or 24 hours snowfall is greater than 10.0 mm or the snow depth reaches 8 cm.
