When cumulus congestus clouds produce rain they are called cumulonimbus clouds. Cumulonimbus clouds often form flat, anvil-like tops. These are known as thunderheads and usually bring rain, thunder, and lightning.

Do cumulus clouds indicate fair weather?
Towering cumulus clouds usually indicate fair, dry conditions. The bases of these clouds form at altitudes below 2000 m. They are mostly made of drops of water. Cumulus – known as fair-weather clouds because they usually indicate fair, dry conditions.
Do cumulus clouds mean rain?
Normally, cumulus clouds produce little or no precipitation, but they can grow into the precipitation-bearing congestus or cumulonimbus clouds. Cumulus clouds can be formed from water vapour, supercooled water droplets, or ice crystals, depending upon the ambient temperature.
What kind of weather does the cumulus cloud bring?
What weather is associated with cumulus clouds? Mostly, cumulus indicates fair weather, often popping up on bright sunny days. Though if conditions allow, cumulus can grow into towering cumulus congestus or cumulonimbus clouds, which can produce showers.
Which cloud is most likely to cause rain?
Most forms of heavy precipitation fall from cumulus clouds. The weather they bring depends on their height and size. The higher the base of a cloud is, the drier the atmosphere and the fairer the weather will be. Clouds located close to the ground mean heavy snow or rain.
What is the 4 types of clouds?
The Four Core Types of Clouds
- Cirro-form. The Latin word 'cirro' means curl of hair. ...
- Cumulo-form. Generally detached clouds, they look like white fluffy cotton balls. ...
- Strato-form. From the Latin word for 'layer' these clouds are usually broad and fairly wide spread appearing like a blanket. ...
- Nimbo-form.
Why do cirrus clouds indicate a change in weather?
What weather is associated with cirrus clouds? They often form in advance of a warm front, where the air masses meet at high levels, indicating a change in the weather is on the way. Technically these clouds produce precipitation but it never reaches the ground. Instead, it re-evaporates, creating virga clouds.
Do cirrus clouds bring rain?
They are wispy, being composed entirely of ice crystals falling through the atmosphere. If Cirrus are carried horizontally by winds moving at different speeds, they take a characteristic hooked shape. Only at very high altitudes or latitudes do Cirrus produce rain at ground level.
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.
Is fog a cloud?
Fog is a kind of cloud that touches the ground. Fog forms when the air near the ground cools enough to turn its water vapor into liquid water or ice. There are many different types of fog, too. Ice fog forms when the air near the ground is cold enough to turn the water in fog into ice crystals.
What is the most dangerous type of cloud?
Cumulonimbus can form alone, in clusters, or along cold front squall lines. These clouds are capable of producing lightning and other dangerous severe weather, such as tornadoes and hailstones. Cumulonimbus progress from overdeveloped cumulus congestus clouds and may further develop as part of a supercell.
Why are cumulus clouds fluffy?
The word "cumulus" is Latin for the word "heap.". When warm, moist air rises, water vapor eventually cools and condenses on particles (called condensation nuclei) into tiny water droplets. As the process continues, water droplets continue to accumulate upwards, creating heaps visible in the sky as white, fluffy clouds.
What are 5 major types of clouds?
Ten Basic Clouds
- Cirrus (Ci), Cirrocumulus (Cc), and Cirrostratus (Cs) are high level clouds. ...
- Altocumulus (Ac), Altostratus (As), and Nimbostratus (Ns) are mid-level clouds They are composed primarily of water droplets. ...
- Cumulus (Cu), Stratocumulus (Sc), Stratus (St), and Cumulonimbus (Cb) are low clouds composed of water droplets.
