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.

Is a cumulus cloud a rain cloud?
Cumulus clouds are puffy clouds that sometimes look like pieces of floating cotton. The base of each cloud is often flat and may be only 1000 meters (3300 feet) above the ground. … These clouds grow upward, and they can develop into a giant cumulonimbus, which is a thunderstorm cloud.
What do cumulus clouds indicate?
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.
What type of clouds indicate rain?
(«Nimbus» comes from the Latin word for «rain.») Two examples are the nimbostratus or cumulonimbus clouds. Nimbostratus clouds bring continuous precipitation that can last for many hours. These low-level clouds are full of moisture. Cumulonimbus clouds are also called thunderheads.
Do all clouds produce rain?
We know that not all clouds produce rain that strikes the ground. Some may produce rain or snow that evaporates before reaching the ground, and most clouds produce no precipitation at all. When rain falls, we know from measurements that the drops are larger than one millimeter.
Do stratus clouds bring rain?
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 the 4 types of clouds?
The different types of clouds are cumulus, cirrus, stratus and nimbus.
Are cumulus clouds dangerous?
Thus, cumulonimbus are known to be extremely dangerous to air traffic, and it is recommended to avoid them as much as possible. Cumulonimbus can be extremely insidious, and an inattentive pilot can end up in a very dangerous situation while flying in apparently very calm air.
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 is the most dangerous 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 do clouds look dark before it rains?
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 clouds do not indicate a dangerous storm?
2. The following clouds do not indicate a dangerous storm: A. cirrus, stratus and cumulonimbus.
Do cirrus clouds bring rain?
Only at very high altitudes or latitudes do Cirrus produce rain at ground level. But if you notice that Cirrus begins to cover more of the sky, and gets lower and thicker, this is a good indication that a warm front is approaching.
Why do clouds not result in 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.
Why dont all rain clouds bring rain?
The droplets of water in a cloud have weight, so gravity gradually polls them down and they sink lower and lower. As most of them fall, they reach a warmer layer of air, and this warmer air causes them to evaporate.So here we have clouds that don’t produce rain.
Can you touch a cloud?
It’s the same with water droplets. Although we can see clouds, if you were to try to touch one your hand would go straight through it. … Although we can’t really touch clouds you could walk through one. In fact that’s what fog is: a cloud that’s formed close to the ground instead of high in the sky.
