It is distinguished from cloud and virga in that it must reach the ground. A fall or descent of rain; the water, or amount of water, that falls in rain; as, the average annual rainfall of a region. A reaction that leads to the formation of a heavier solid in a lighter liquid; the precipitate so formed at the bottom of the container.
A deposit on the earth of hail, mist, rain, sleet, or snow; also, the quantity of water deposited. In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds. The main forms of precipitation include drizzling, rain, sleet, snow, ice pellets, graupel and hail. Published: 23 Apr, Rainfall noun meteorology the amount of rain that falls on a single occasion. Precipitation noun meteorology Any or all of the forms of water particles, whether liquid or solid, that fall from the atmosphere e.
Rainfall noun A fall or descent of rain; the water, or amount of water, that falls in rain; as, the average annual rainfall of a region. Precipitation noun A hurried headlong fall. Rainfall noun water falling in drops from vapor condensed in the atmosphere.
Precipitation noun A reaction that leads to the formation of a heavier solid in a lighter liquid; the precipitate so formed at the bottom of the container. Precipitation noun figuratively Unwise or rash rapidity; sudden haste. Precipitation noun The act of precipitating, or the state of being precipitated, or thrown headlong. Precipitation noun A falling, flowing, or rushing downward with violence and rapidity. Precipitation noun Great hurry; rash, tumultuous haste; impetuosity.
Precipitation noun The act or process of precipitating from a solution. Precipitation noun A deposit on the earth of hail, mist, rain, sleet, or snow; also, the quantity of water deposited.
Precipitation noun the process of forming a chemical precipitate. Raindrops frequently fall when small cloud particles strike and bind together, creating bigger drops.
As this process continues, the drops get bigger and bigger to an extent where they become too heavy to suspend on the air. As a result, the gravity pulls then down to the earth. When high in the air, the raindrops start falling as ice crystals or snow but melt when as they proceed down the earth through the warmer air.
Rainfall rates vary from time to time, for example, light rain ranges from rates of 0. Rain is the most common component of the water cycle and replenishes most of the freshwater on the earth. Snow occurs almost every time there is rain. It is precipitation in the form of virga or flakes of ice water falling from the clouds. Snow is normally seen together with high, thin, and weak cirrus clouds.
Snow can at times fall when the atmospheric temperatures are above freezing, but it mostly occurs in sub-freezing air. When the temperatures are above freezing, the snowflakes can partially melt but because of relatively warm temperatures, the evaporation of the particles occurs almost immediately.
This evaporation leads to cooling just around the snowflake and makes it to reach to the ground as snow. Snow has a fluffy, white, and soft structure and its formation is in different shapes and ways, namely flat plates, and thin needles. Each type of snow forms under specific combinations of atmospheric humidity and temperatures. The process of snow precipitation is called snowfall.
Sleet takes place in freezing atmospheric conditions. The following equivalents show the relationship between the volume and weight of water and between the volume and speed of flowing water.

Higher in the sky where it is colder than at the land surface, invisible water vapor condenses into tiny liquid water droplets—clouds. When the cloud droplets combine to form heavier cloud drops which can no longer "float" in the surrounding air, it can start to rain, snow, and hail Perhaps you've never seen snow. Or, perhaps you built a snowman this very afternoon and perhaps you saw your snowman begin to melt.
Regardless of your experience with snow and associated snowmelt, runoff from snowmelt is a major component of the global movement of water, possibly even if you live where it never snows. The air is full of water, as water vapor, even if you can't see it. Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.
Ice and glaciers are part of the water cycle, even though the water in them moves very slowly. Ice caps influence the weather, too. The color white reflects sunlight heat more than darker colors, and as ice is so white, sunlight is reflected back out to the sky, which helps to create weather patterns.
Read on to learn how glaciers and ice caps are part of the water cycle. We all know that raindrops are shaped like teardrops, right? Actually, that is not true. Read on to find out the facts. Data from rain gages that provide real-time data are relayed to the USGS and are transmitted from each station at hourly intervals. Real-time data available on these web pages are provisional data that have not been reviewed or edited.
Here is a classic rainstorm during the summer, as that is when more localized storms occur. Other rain events are more "frontal" in nature, with large formations of featureless and uniform nimbostratus types of clouds bringing precipitation over a large area.
But often you see a landscape similar to. There are actually three rainbows in the sky, with three more being seen in the lake reflection. When they get larger than a radius of about 4. When the cloud droplets combine to form heavier cloud drops which can no longer "float" in the surrounding air, it can start to rain, snow, and hail.
When rain hits the ground it begins to flow overland downhill. These are different types of precipitation, but what does 'precipitation' mean? When we talk about precipitation, we are talking about water that is falling out of the sky, this could be rain, drizzle, snow, sleet, hail or something rarer!
But most of the time in the UK it's rain, so if you hear someone using the word 'precipitation' it probably means that the weather is going to bring a mix of different types or phases of water falling out of the sky, such as a mix of rain and hail. It is important to know which type of precipitation the weather is going to bring as it can tell you about other things going on in the atmosphere, as well as what you might need to do, like taking an umbrella or getting ready to build a snowman!
Rain is the type of precipitation we see most of the time in the UK; it is water in its liquid state.
