How do clouds form

Airplanes create hole-punch clouds — but just how do they do it?

How Long do Contrails Last?

He said people who look out their airplane window in flight can see for themselves how the wing changes a cloud. Lenticular clouds are caused by a wave wind pattern created by the mountains. Water vapor gets into air mainly by evaporation — some of the liquid water from the ocean, lakes, and rivers turns into water vapor and travels in the air.

How air becomes saturated[ edit ] Main article: They often grow into cumulonimbus clouds, which produce thunderstorms. This is called condensation. The latter has been horizontally compressed in this depiction.

Why do clouds float when they have tons of water in them?

There are a few species, each of which can be associated with genera of more than one physical form. As it rises, its pressure and temperature drop causing water vapor to condense. Because contrails are generally made of ice crystals. From satellite imagery you could see holes just pocketing the sky, holes and long channels where aircraft had been flying at that level of the cloud for a while.

They might list things such as the sun, stars, the moon, rain, birds and clouds. Altostratus is usually composed of water droplets but may be mixed with ice crystals at higher altitudes. Then the second thing we did was say, okay, why do these long channels last for the period of time it would take for a satellite to take a snapshot of them?

How Clouds Form

He believed that the changing cloud forms in the sky could unlock the key to weather forecasting. They resemble fog that doesn't reach the ground. Within these layers of the atmosphereair can become saturated as a result of being cooled to its dew point or by having moisture added from an adjacent source.

The clouds usually cover the entire sky. These forms are commonly used for the purpose of satellite analysis. Clouds that produce rain like nimbostratus and cumulonimbus are also common at warm fronts.

At a warm front, where a warm air mass slides above a cold air mass, the warm air is pushed upward forming many different types of clouds — from low stratus clouds to midlevel altocumulus and altostratus clouds, to high cirrus, cirrocumulus and cirrostratus clouds.

There are a few species, each of which can be associated with genera of more than one physical form. By watching the movement of cirrus clouds you can tell from which direction weather is approaching. The cloud base takes on a darker grey coloration and the top commonly resembles a cauliflower.

And the cooling produces a cloud.In August, we posted a photograph of some odd, rare clouds known as Morning Glory clouds without providing an explanation for how they form.

How Clouds Form

In response to reader interest, we followed up with. How do hurricanes form? Hurricanes only form over warm ocean waters of about 80°F.

This is why it is common in the tropics where temperatures are high all year round. How do clouds form?: Clouds form when the water vapour goes up into the sky and creates a cloud What is a cloud cloud is a hard uncomfortable soft looking thing.

The Aeronomy of Ice in the Mesosphere (AIM) NASA satellite mission is exploring PMCs. duplicatus, undulatus fibratus nebulosus Cirrostratus undulatus, lacunosus stratiformis lenticularis castellanus floccus Cirrocumulus intortus, radiatus, vertebratus.

How Do Clouds Form?

In meteorology, a cloud is an aerosol consisting of a visible mass of minute liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body. Water or various other chemicals may compose the droplets and crystals.

On Earth, clouds are formed as a result of saturation of the air when it is cooled to its dew point.
