Why do clouds look dark before it rains?
White is how our eyes perceive all wavelengths of sunlight mixed together.
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..
Why do clouds not form on the ground?
But the reason most clouds are not is that usually the ground is the warmest part of the troposphere (the part of the atmosphere where clouds form and weather occurs). The warm air rises and cools to saturation, which causes condensation, which forms a cloud.
Do clouds fly?
Clouds do exist, and they do float in the air. … The warm, moist air is less dense than the cold air above it, so that warm air rises2. The warm air cools as it comes into contact with the cooler air above. Cold air cannot hold as much moisture as warm air: the vapor has to condense into a liquid.
Are clouds liquid or gas?
Water vapor is a gas and is absolutely invisible. Liquid water, even in very tiny droplets such as those found in clouds, however, is visible. It is important for students to realize that cloud formation is the result of condensation. The droplets of water in a cloud, however, are much smaller than those in a raindrop.
What do clouds tell us?
Cirrus clouds are usually white and predict fair to pleasant weather. By watching the movement of cirrus clouds you can tell from which direction weather is approaching. When you see cirrus clouds, it usually indicates that a change in the weather will occur within 24 hours. … The clouds usually cover the entire sky.
What is the biggest cloud?
The highest clouds in the atmosphere are cirrocumulus, cirrus, and cirrostratus. Cumulonimbus clouds can also grow to be very high. Mid-level clouds include altocumulus and altostratus. The lowest clouds in the atmosphere are stratus, cumulus, and stratocumulus.
Are clouds heavy?
They may look all light and fluffy, but the reality is that clouds are actually pretty heavy. Researchers have calculated that the average cumulus cloud – which is that nice, white fluffy kind you see on a sunny day – weighs an incredible 500,000 kg (or 1.1 million pounds!).
Why is fog dangerous?
Fog consists of water droplets suspended in the air; driving through heavy fog is a bit like flying through a cloud. … As a result, fog is often heaviest at night and in the morning. If possible, wait until mid- or late afternoon, by which point the fog is likely to have burned off.
Can we make artificial clouds?
Methodology. The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice (solid carbon dioxide). Liquid propane, which expands into a gas, has also been used. This can produce ice crystals at higher temperatures than silver iodide.
What are high clouds formed from?
Clouds at higher and extremely cold levels in the atmosphere are composed of ice crystals – these can be about a tenth of a millimeter long. Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals.
Can you touch clouds?
You cannot “touch” the cloud when it is all around you. It’s something like the air around you. … Fog is a thick cloud of tiny water droplets suspended in the atmosphere at or near the earth’s surface which obscures visibility.
Is fog a cloud?
Clouds can form at many different altitudes. They can be as high as 12 miles above sea level or as low as the ground. 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.
Why do clouds look fluffy?
When warm air rises from the ground, it carries water vapor with it. When the water vapor meets the cold air found high in the sky, the gas condenses to liquid and forms cumulus clouds. While these fluffy-white clouds look like soft pillows of cotton, they are actually composed of small water droplets.
Can I eat a cloud?
Eating parts of a cloud certainly can’t harm you(side note: you can’t eat water, you drink it). … In other words, no, you most certainly cannot eat a cloud. The day somebody does is the day we don’t have water resource problems. Just go ahead, see if you can eat a cloud.
How high can clouds go?
At the upper reaches of the troposphere you’ll find high clouds, which, depending on geographic location, occur between roughly 10,000 and 60,000 feet. Below that is the home of mid-level clouds, which generally occur between 6,000 and 25,000 feet.
Where are the clouds coming from?
A cloud is made up of liquid water droplets. A cloud forms when air is heated by the sun. As it rises, it slowly cools it reaches the saturation point and water condenses, forming a cloud. As long as the cloud and the air that its made of is warmer than the outside air around it, it floats!
Do clouds smell?
Lightning inside of clouds produces ozone—that’s the smell that tells you that a storm is on the way. Ozone is made up of three oxygen atoms, and has sort of a light chlorine smell, says Dalton. Some people might describe it as fresh, others as a little sharp.
Do clouds move?
Clouds move because the wind is carrying the parcel of cloudy air along. Wind occurs at all levels of the atmosphere from the ground up to higher than a jumbo jet can fly. Sometimes there can be no wind on the ground, but cirrus clouds very high up can be seen moving because of the wind where they are.
Why do clouds turn pink?
Red, orange and pink clouds occur almost entirely at sunrise and sunset and are the result of the scattering of sunlight by the atmosphere. … Clouds look darker in the near-infrared because water absorbs solar radiation at those wavelengths.
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.
Do clouds feel wet?
Fog and clouds are both made of tiny water droplets – like the ones you can sometimes see or feel in a hot, steamy shower. Clouds form through evaporation and condensation.
Why are clouds white?
But in a cloud, sunlight is scattered by much larger water droplets. These scatter all colours almost equally meaning that the sunlight continues to remain white and so making the clouds appear white against the background of the blue sky.
What do dark clouds symbolize?
White clouds are associated with happy days, while dark clouds are often used by movie-makers and in our dreamscapes to indicate a more ominous feeling. White is associated with purity, innocence and protection. Blood is the life force.
