Why Do Clouds Have Flat Bottoms?
As warm air rises the water vapour remains invisible until the air cools enough for it to condense into water droplets. The altitude where that happens marks the bottom of the cloud. Providing that more air feeds in from below new cloud will form there and preserve the flat bottom.
Why are clouds flat underneath?
You are referring to cumulus clouds (and to cumulonimbus). Cumulus clouds are indeed flat-bottomed because they ride atop currents of rising warm air (warmer than the air surrounding them).
Cumulus clouds those puffy clouds common in the sky during warm days especially in the summer are indeed flat-bottomed. It’s because of the way they form. They exist at the top of columns of warm air rising into the sky from the ground. Sunshine heats the ground and the ground heats the air above it.
What does a flat cloud mean?
Why are clouds fluffy on top?
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.
Why do clouds float?
What is a white fluffy cloud called?
Do altostratus clouds rain?
Altostratus clouds are “strato” type clouds (see below) that possess a flat and uniform type texture in the mid levels. … However altostratus clouds themselves do not produce significant precipitation at the surface although sprinkles or occasionally light showers may occur from a thick alto- stratus deck.
Which clouds bring heavy rain?
These low-level clouds are full of moisture. Cumulonimbus clouds are also called thunderheads. Thunderheads produce rain thunder and lightning. Many cumulonimbus clouds occur along cold fronts where cool air is forced under warm air.
What does it mean if you see a baby in the clouds?
BABY: As babies are a symbol of ‘new beginnings’ seeing their image in a cloud can indicate a new phase or fresh start in your life. It may also indicate the undertaking of a new important project.

Why do clouds not fall?
Water is not lighter than air – water does not float. So why don’t clouds fall out of the sky? The two biggest reasons that clouds stay in the sky are 1) small drops and 2) wind. … Because small drops have less mass and more surface area than large drops they have a harder time pushing the air out of the way.
Can you physically touch a cloud?
Why do clouds turn GREY?
When clouds are thin they let a large portion of the light through and appear white. But like any objects that transmit light the thicker they are the less light makes it through. As their thickness increases the bottoms of clouds look darker but still scatter all colors. We perceive this as gray.
What are the four families of clouds?
For identification purposes you need be con- cerned only with the more basic cloud types which are divided into four “families.” The families are: high clouds middle clouds low clouds and clouds with extensive vertical development.
What are dark clouds called?
Cumulonimbus clouds are cumulus clouds that have grown very high into the atmosphere. Also called thunderheads cumulonimbus clouds have bases that are usually dark and their tops often resemble the shape of an anvil.
Do clouds have names?
Well clouds have names too! Some cloud names are cirrus cumulus and stratus. … “Names” can be for individual things or for groups of things (e.g. a cirrus cloud may be one individual cloud or it may refer to that group of cloud types.

What clouds produce snow?
Altostratus Clouds – Altostratus clouds also known as snow clouds are gray or blue-gray clouds that completely cover the sky. They’re made of dense ice crystals and water droplets that can precipitate either continuous rain or snow.
How long does a cloud last?
The average lifespan of a cumulus cloud is less than one hour after which it either turns to a cumulonimbus cloud or tends to disintegrate.

Does a tornado have to have a wall cloud?
Why do clouds look like cotton balls?
This warmed air rises by convection and forms Cumulus. 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.
What do black clouds mean?
A: Very dark looking or black clouds are probably those that contain a lot of rain in them and part of a thunderstorm McRoberts adds. “In general the severity of a storm is related to cloud height which is why dark clouds are usually an indicator of bad weather.
