Antwort Can it rain inside a cloud? Weitere Antworten – How does rain form in clouds
Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain. Come to think of it, what makes it snow, hail, and sleet All these forms of water don't fall out of a clear, blue sky.Cloud seeding is the opposite of cloud busting.Even though a cloud weighs tons, it doesn't fall on you because the rising air responsible for its formation keeps the cloud floating in the air. The air below the cloud is denser than the cloud, thus the cloud floats on top of the denser air nearer the land surface.
What are clouds made of : Clouds appear when there is too much water vapour for the air to hold. The water vapour (gas) then condenses to form tiny water droplets (liquid), and it is the water that makes the cloud visible. These droplets are so small that they stay suspended in the air.
Why are clouds white
But in a cloud, sunlight is scattered by much larger water droplets. These scatter all colours almost equally meaning that the sunlight continues to remain white and so making the clouds appear white against the background of the blue sky.
Which cloud produces rain : Cumulonimbus and nimbostratus clouds are the types that bring us the majority of our rain. The term "nimbus" originates from Latin and means rain, so its prefix and suffix forms nimbo- and -nimbus are fitting to denote clouds that give us rain.
Most cloud seeding operations, including those run by DRI, use a compound called silver iodide (AgI) to aid in the formation of ice crystals. Silver iodide exists naturally in the environment at low concentrations, and is not known to be harmful to humans or wildlife.
Some of the potential environmental risks of cloud seeding include: Altering the natural balance of precipitation: Cloud seeding can alter the natural balance of precipitation, which could have negative impacts on the environment. For example, it could lead to flooding in some areas and drought in others.
Why do clouds turn GREY
So why are clouds sometimes grey Cloud bases are often grey as a result of the same scattering that makes them white. When light is scattered in a cloud it usually is sent back upwards, or out to the sides of the cloud, making the tops and sides of the cloud whiter than the base which receives less light.While it's true that clouds contain water, they actually aren't made of water vapor. If they were, you wouldn't be able to see them. The water that makes up clouds is in liquid or ice form. The air around us is partially made up of invisible water vapor.Depending on their type, clouds can consist of dry air mixed with liquid water drops, ice particles, or both. Low, shallow clouds are mostly made of water droplets of various sizes. Thin, upper level clouds (cirrus) are made of tiny ice particles.
A cloud is defined as 'a visible aggregate of minute droplets of water or particles of ice or a mixture of both floating in the free air'. Each droplet has a diameter of about a hundredth of a millimeter and each cubic meter of air will contain 100 million droplets.
Why did clouds turn grey : Clouds are made up of tiny water droplets or ice crystals, but usually a mixture of both. The water and ice scatter all light, making clouds appear white. If the clouds become thick enough or high enough, all the light above does not make it through the cloud. Therefore, it looks gray or dark.
Why do clouds turn grey : Thicker clouds look darker than thinner ones, which let more light through and so appear white. Richard Brill, a professor at Honolulu Community College, gives this answer: It is the thickness, or height of clouds, that makes them look gray. Clouds are made of tiny droplets of water or ice.
Which cloud has no rain
Stratus clouds are uniform and flat, producing a gray layer of cloud cover which may be precipitation-free or may cause periods of light precipitation or drizzle.
A 1 cubic kilometer (km3) cloud contains 1 billion cubic meters. Doing the math: 1,000,000,000 x 0.5 = 500,000,000 grams of water droplets in our cloud. That is about 500,000 kilograms or 1.1 million pounds (about 551 tons).meteorologist Vincent J. Schaefer
The first experiments with cloud seeding were conducted in 1946 by American chemist and meteorologist Vincent J. Schaefer, and since then seeding has been performed from aircraft, rockets, cannons, and ground generators.
How good is cloud seeding : Although not a panacea for drought-stricken regions, cloud-seeding can increase seasonal precipitation by about 10%. In the Reno area alone, winter cloud-seeding efforts are estimated to add enough water to supply about 40,000 households for a year. Microscopic view of snowflakes by Wilson Bentley.
