What kind of clouds have flat bottoms?
Cumulus clouds are, indeed, flat-bottomed because they ride atop currents of rising warm air (warmer than the air surrounding them).
What does flat-bottomed clouds mean?
These “fair weather” clouds look like cotton wool. If you look at a sky filled with cumulus, you may notice they have flat bases, which all lie at the same level. At this height, air from ground level has cooled to the dew point. Cumulus clouds do not generally rain – you're in for fine weather.
Why do clouds look flat on the bottom and fluffy on top?
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.
Why do clouds flatten at the top?
The cool shape that you see with the flat top is due to rising air in storms. The air expands and spreads out as the air hits the bottom of the stratosphere. The name anvil comes from its similar look to a tool that is used by metal workers.
Why are clouds straight?
The line is so straight because Sun's light is just barely grazing the bottom of the wispy clouds. That line is the geometric projection of only the bit of the cloud that's throwing the shadow at just the right altitude.
What cloud is called mares tail?
cirrus cloud These are a type of cirrus cloud, known as cirrus uncinus. The name is derived from Latin and means "curly hooks". The clouds occur at very high altitudes, at a temperature of about −50 to −40C. They are commonly known as mares' tails because of their likeness to horse tails.
Why are clouds flat on the bottom Reddit?
Add in the fact that warm air rises because it's less dense, and warm sea-level-pressure air can hold more dissolved invisible moisture than cold lower-pressure air, and you have your ingredients to a flat-bottomed cloud.
What do anvil clouds mean?
A cumulonimbus incus (Latin incus, "anvil") also known as an anvil cloud is a cumulonimbus cloud which has reached the level of stratospheric stability and has formed the characteristic flat, anvil-top shape. It signifies the thunderstorm in its mature stage, succeeding the cumulonimbus calvus stage.
What is the highest cloud ever recorded?
Astronomers have discovered the largest and oldest mass of water ever detected in the universe — a gigantic, 12-billion-year-old cloud harboring 140 trillion times more water than all of Earth's oceans combined.
What is the rarest cloud?
Kelvin Helmholtz Waves are perhaps the rarest cloud formation of all. Rumored to be the inspiration for Van Gogh's masterpiece “Starry Night”, they are incredibly distinctive. They are mainly associated with cirrus, altocumulus, and stratus clouds over 5,000m.
What are the straight clouds called?
Cloud streets are long rows of cumulus clouds that are oriented parallel to the direction of the wind. Their technical name, more specifically, is horizontal convective rolls.
What are the clouds that look like cotton balls?
Cumulus clouds are puffy shaped. They may look like popcorn or cotton and have flat bottoms. They are low in the sky.
What do herringbone clouds mean?
It appears as a rippling type pattern in the sky and it can look like fish scales in the sky. This is caused by moisture in the mid levels that get trapped between dry air at the surface and dry cold air in high levels of in the atmosphere.
Why are clouds puffy?
The fluffy appearance of the tops of some clouds are evidence of convection, when buoyant air parcels within the cloud literally bubble to the top. As the air rises, it encounters environments with lower and lower pressure and cools by expansion. This cooling increases the relative humidity of the air.
What is the rarest type of cloud?
Kelvin Helmholtz Waves are perhaps the rarest cloud formation of all. Rumored to be the inspiration for Van Gogh's masterpiece “Starry Night”, they are incredibly distinctive. They are mainly associated with cirrus, altocumulus, and stratus clouds over 5,000m.
Are anvil clouds rare?
(WMC) – The thunderstorm anvil cloud is a common cloud and they can be spotted on any given hot summer day in the Mid-South. An anvil cloud is made of ice particles; these frozen particles form in the highest levels of thunderstorms or cumulonimbus clouds.
How old is the oldest cloud?
12-billion-year-old Astronomers have discovered the largest and oldest mass of water ever detected in the universe — a gigantic, 12-billion-year-old cloud harboring 140 trillion times more water than all of Earth's oceans combined.
Can we touch clouds?
Clouds are made of millions of these tiny liquid water droplets. The droplets scatter the colors of the sunlight equally, which makes clouds appear white. Even though they can look like cushy puffballs, a cloud can't support your weight or hold anything up but itself.
Why do clouds have holes?
As a plane flies through mid-level clouds, it forces air to expand rapidly and cool. Water droplets in the cloud freeze to ice and then turn to snow as they fall. The gap expands to create spectacular holes in the clouds.
What do clouds look like before a tornado?
Tail cloud Tail clouds look like a funnel or tornado in many ways. They are often bent on an axis that is not quite horizontal and not quite vertical. While they are not themselves dangerous, like a wall cloud, tail clouds are often indicative of severe weather and potential tornadic activity.
What are flat gray clouds called?
Stratus clouds 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.
What is a buttermilk sky?
noun. a cloudy sky resembling the mottled or clabbered appearance of buttermilk.
What are nimbus clouds?
A nimbus cloud is a cloud that produces precipitation. Usually the precipitation reaches the ground as rain, hail, snow, or sleet. Falling precipitation may evaporate as virga. Since nimbus clouds are dense with water, they appear darker than other clouds.
How long does a cloud last?
Although they typically last for only 4-6 hours, some clusters have been observed to last more than 14 hours and travel thousands of kilometers before dissipating.
What are GREY clouds called?
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.
What will happen if you touch a cloud?
Clouds are made of millions of these tiny liquid water droplets. The droplets scatter the colors of the sunlight equally, which makes clouds appear white. Even though they can look like cushy puffballs, a cloud can't support your weight or hold anything up but itself.
What is the rarest cloud type?
Kelvin Helmholtz Waves are perhaps the rarest cloud formation of all. Rumored to be the inspiration for Van Gogh's masterpiece “Starry Night”, they are incredibly distinctive. They are mainly associated with cirrus, altocumulus, and stratus clouds over 5,000m.
What is the weirdest type of cloud?
Lenticular clouds take the visual form of a flying saucer, which gives them their nickname of “UFO clouds.” These clouds form in mountainous regions (this particular picture is from Mauna Kea, HI). When stable, moist air streams over a mountain and is heated, it condenses into this lens-shaped cloud.
Can you touch a cloud?

What happens if you touch a rainbow?
In short, you can touch someone else's rainbow, but not your own. A rainbow is light reflecting and refracting off water particles in the air, such as rain or mist. The water particles and refracted light that form the rainbow you see can be miles away and are too distant to touch.
