Why are clouds fluffy?

If a cloud contains more ice particles than water droplets (or all ice particles) it appear to have a "fluffy" edge to it (example: Cirrus

Cirrus

Cirrus (cloud classification symbol: Ci) is a genus of high cloud made of ice crystals. Cirrus clouds typically appear delicate and wispy with white strands. Cirrus are usually formed when warm, dry air rises, causing water vapor deposition onto rocky or metallic dust particles at high altitudes.

clouds). The wind blows the ice crystals giving a wispy, thin white appearance.

Why are clouds fluffy on top but flat on bottom?

As the air continues to rise, that first chunk of cloud gets pushed up as more cloud forms beneath, resulting in a cloud that's puffy on top but flat on the bottom. That level is called the lifting condensation level (LCL) or convective condensation level (CCL), depending on the lifting mechanism.

Are clouds always fluffy?

“Although most clouds look light and fluffy, they are in fact highly turbulent with very strong air currents within them and an enormous mass of suspended water,” he says.

How do clouds stay up if they are so heavy?

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.

How does water fluff into clouds?

They are made of liquid water. As the water vapour condenses, the beginnings of a cloud can be seen. As the rest of the warm, moist air pocket rises, it will also cool and condense. This is what creates a cloud with a flat bottom that appears to grow tall and fluffy!

Ask Ellen: Why do some clouds have flat bottoms and puffy tops?

Are clouds gas or liquid?

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.

What holds clouds in the sky?

Water droplets in air behave the same way as dust⁶. The second reason that clouds can float in the air is that there is a constant flow of warm air rising to meet the cloud: the warm air pushes up on the cloud and keeps it afloat.

Can planes fly through clouds?

Moreover, the turbulence inside a cloud can become extreme and break apart an aircraft. Thus, it is extremely dangerous to fly inside such a system.

Why do clouds turn GREY?

As the size and concentration of the hydrometeors increases, less and less sunlight penetrates the cloud, resulting in multiple scattering. We perceive these clouds as dark clouds in varying shades of grey.

What pulls rain down?

Eventually, the droplets in the clouds are heavy enough to be pulled down by gravity — and that's rain!

Why do clouds get big?

Turbulent currents in the clouds provide the first collisions between droplets. The combination forms a larger drop which can further collide with other droplets, thus growing rapidly in size. As the drops grow, their fall velocity also increases, and thus they can collide with slower falling droplets.

Why are rain clouds dark?

When it's about to rain, clouds darken because the water vapor is clumping together into raindrops, leaving larger spaces between drops of water. Less light is reflected. The rain cloud appears black or gray. Clouds form when air becomes saturated, or filled, with water vapor.

How heavy can clouds get?

Answer: Thus, a 'typical' fair weather cumulus cloud "weighs" about 1 billion 400 million pounds, or about 800 million pounds less than dry air of equal volume. Thats a lot of weight!

Why are clouds white?

In a cloud sunlight is scattered equally, meaning that the sunlight continues to remain white and gives clouds their distinctive white appearance.

What are clouds made of?

A cloud is made of water drops or ice crystals floating in the sky. There are many kinds of clouds. Clouds are an important part of Earth's weather.

Is it colder when there are no clouds?

On clear nights, there are no clouds in the sky to trap heat. As a result, heat is able to escape Earth's atmosphere. The temperature drops. That's why clear nights can be quite a bit colder than cloudy nights.

Would a cloud be wet?

Clouds are composed of liquid suspended water droplets in about a 100% RH environment.

Do clouds ever go away?

Do Clouds Really Disappear? Clouds do not disappear. They just become invisible water vapor by different mechanisms. Usually, the micro-droplets of water are transformed into another form of water.

How do pilots see at night?

At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres. Using this instrument, the pilot can determine whether the aircraft is in a climb, a dive, or rolling.

What clouds should you avoid flying?

Cumulonimbus: Nature's detour sign for planes can cause a bumpy flight. As you might guess, storm clouds – specifically cumulonimbus – are the types of clouds that pilots most want to avoid. Cumulonimbus clouds generally contain heavy rain, lightning, hail, strong winds and occasionally tornadoes.

Why do planes shake in clouds?

The most common cause of turbulence is due to turbulent air in Earth's atmosphere. The jet streams around Earth can cause sudden changes in the wind speed that can rock airplanes. Thermal turbulence can occur; this is created by hot rising air from cumulus clouds or thunderstorms.

Can you touch the clouds in the sky?

For reference, raindrops are usually 1 or 2 mm but can be as large as 4 - 5 mm, so this is at least 100 times smaller than a raindrop. Nonetheless, if you were to be able to touch a cloud, it wouldn't really feel like anything, just a little wet.

How does rain come out of the clouds?

What causes rain? Clouds are made of water droplets. 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.

What is it called when a cloud falls from the sky?

Fallstreak holes, also known as hole-punch clouds, are the result of cold air temperatures and atmospheric instability. Viewed from below, it can appear as if part of the cloud is falling out of the sky. As it turns out, that is actually what's happening.
