Thickness of the layer of water which accumulates on a horizontal surface, as the result of precipitation, in the absence of infiltration or evaporation
The total liquid product of precipitation or condensation from the atmosphere as received and measured in a rain gauge in past 24 hours at 03 UTC. Classification of rainfall is as follows: Very heavy Rainfall more than 12.5 cm Heavy Rainfall 6.5 to 12.5 cm Rather heavy Rainfall 3.5 to 6.5 cm Moderate Rainfall 0.8 to 3.5 cm Light rain Rainfall 0.3 to 0.7 cm Very light rain Rainfall up to 0.2 cm No rain When there is zero rainfall. Rainfall Distribution: Spatial distribution of rainfall is highly variable. The following criteria are used in forecasting practices . Isolated When rainfall occurred 25 % or less of the total area under observation Scattered When rainfall occurred 26 to 50 % of the total area under observation. Fairly Widespread When rainfall occurred 51 to 75 % of the total area under observation. Light rain Rainfall 0.3 to 0.7 cm Very light rain Rainfall up to 0.2 cm No rain When there is zero rainfall.
The quantity of water that falls as rain only.
the amount of precipitation (rain, hail, etc.) expressed in millimeter depth, of the layer of water which has fallen. (Philippine Atmospheric, Geophysical and Astronomical Services Administration)
Point Precipitation: That which registers at a single gauge. Area Precipitation: Adjusted point rainfall for area size.
The amount of precipitation of any type (including the liquid equivalent of frozen hydrometeors); usually taken as that amount measured by means of a rain gauge (thus a small, varying amount of direct condensation is included). A more accurate term would be precipitation or precipitation amount. However, the broad use of "rainfall" is firmly established in meteorology, especially in hydrologic and climatological literature. Its best utilization would confine it to liquid precipitation, and so would provide a distinction between precipitation immediately accessible to soil and streams and that delayed in storage as snow or ice on the earth's surface.
Rainfall is drops of water that falls from clouds in the sky. Rainfall is measured as the depth of water that falls on a level surface.
(DOD) The water that is precipitated from the base surge clouds after an underwater burst of a nuclear weapon. This rain is radioactive and presents an important secondary effect of such a burst.
The amount of precipitation of any type, primarily liquid. It is usually the amount that is measured by a rain gauge.
