What is precipitation in simple words?
Precipitation is a form of water from the atmosphere.
It is a term in meteorology, and includes rain, snow, sleet, ice pellets dew, frost, and hail.
These form by condensation from atmospheric water vapor, and fall under gravity.
Fog and mist are not precipitation but suspensions..

What does the precipitation percentage mean?
The “Probability of Precipitation” (PoP) simply describes the probability that the forecast grid/point in question will receive at least 0.01″ of rain. So, in this example, there is a 40 percent probability for at least 0.01″ of rain at the specific forecast point of interest!
What does 30% precipitation mean?
More generally, a 30% chance of precipitation means there is, in the opinion of the forecaster, a 30% chance of measurable precipitation in the time period to which it applies ( ”measurable precipitation” is 0.01 inch of precipitation or more). …
Does precipitation mean rain?
A probability of precipitation (POP), also referred to as chance of precipitation or chance of rain, is a measure of the probability that at least some minimum quantity of precipitation will occur within a specified forecast period and location. It is often published with weather forecasts.
What does 60 percent precipitation mean?
If they say 60% chance of rain, 60% of their area will experience rain at some point during the forecast period. … Keep in mind, PoP only refers to the chance of precipitation, NOT how much rain you will get. A 100% chance of rain could mean buckets of rain all day or just a light sprinkle in the afternoon.
Does precipitation mean?
Precipitation is rain, snow, sleet, or hail — any kind of weather condition where something’s falling from the sky. Precipitation has to do with things falling down, and not just from the sky. It’s also what happens in chemical reactions when a solid settles to the bottom of a solution.
What does 40% precipitation mean?
So… if the forecaster knows precipitation is sure to occur ( confidence is 100% ), he/she is expressing how much of the area will receive measurable rain. … If a forecaster is only 50% certain that precipitation will happen over 80 percent of the area, PoP (chance of rain) is 40% (i.e., . 5 x . 8).
What is a high chance of precipitation?
4 or 40%)But, most of the time, the forecaster is expressing a combination of degree of confidence and areal coverage. If the forecaster is only 50% sure that precipitation will occur, and expects that, if it does occur, it will produce measurable rain over about 80 percent of the area, the PoP (chance of rain) is 40%.
Is 30 precipitation a lot?
The forecast of a 30 percent chance of rain can mean all of the area will get rain if it rains, but the forecaster has only a 30 percent confidence that rain will indeed arrive. It can also mean that scattered rain is a certainty, but it will affect only 30 percent of the area.
What is 100% precipitation?
A precipitation chance is a probability that precipitation will occur at a particular location in the forecast area. … A 100% chance guarantees precipitation will occur. A 100% chance will be issued when it is already precipitating or mechanisms are in place to guarantee precipitation.
Is 0.04 inches of rain a lot?
Rainfall rate is generally described as light, moderate or heavy. Light rainfall is considered less than 0.10 inches of rain per hour. Moderate rainfall measures 0.10 to 0.30 inches of rain per hour.
What does 20% precipitation mean?
When a meteorologist says that there is a 20 percent chance of rain, that is not a ”cover your rear” percentage. It usually means that the atmosphere is generally stable but there’s just enough of a particular ingredient (i.e. moisture, heat, lift) to squeeze out a shower of a very limited area.
What is difference between precipitation and rain?
