The thicker a cloud gets, the less light can pass through it. So when you look up at a rain cloud, the base or bottom of it looks gray. But not all dark clouds bring rain, and sometimes this is hard to predict.

Does dark clouds mean rain?
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. The rain cloud appears black or gray. Clouds form when air becomes saturated, or filled, with water vapor.
What type of clouds bring rain?
Among the various types of clouds, three are responsible for most precipitation that falls to Earth: they are stratus, cumulus, and nimbus. These clouds are capable of producing both rain and snow, mostly by combining in hybrid formations.
Which Colour clouds bring rain?
The colour of the clouds that bring us rain is black or dark grey.
What does the dark clouds bring?
The Latin word nimbus means “dark cloud” or “rain storm,” and meteorologists use it to classify two of the major types of rain-bearing clouds: nimbostratus, layered rain clouds that don’t produce lightning, and cumulonimbus, deep cumulus clouds generating lightning, thunder and heavy downpours.
What are dark rain clouds called?
Nimbostratus clouds are dark, gray clouds that seem to fade into falling rain or snow. They are so thick that they often blot out the sunlight.
Do all clouds bring 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.
Why do clouds turn GREY before it rains?
Thicker clouds look darker than thinner ones, which let more light through and so appear white. Richard Brill, a professor at Honolulu Community College, gives this answer: It is the thickness, or height of clouds, that makes them look gray. Clouds are made of tiny droplets of water or ice.
Which clouds do not produce rain?
Cirrus clouds do not produce precipitation which reaches the ground, though streaks of particles (known as fall streaks) are often observed below these clouds.
Why do some clouds not produce rain?
For example, if there aren’t enough droplets of water in a cloud to collide and form large drops, the tiny droplets will stay suspended in the air and it won’t rain. In some very hot and dry places, rain may start to fall from a cloud but the drops evaporate while they are still high in the air.
Why do clouds get dark before a storm?
Clouds appear dark when they are thicker and denser than normal clouds of a day of mild weather. As a cloud gathers more water droplets and ice crystals, it become thicker and allows less light to pass through it.
How does water vapor turn into rain?
Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.
Why are clouds white 10?
All the suspended particles in cloud have size very larger than the wavelength of visible light falling onto it. So, it suffers almost zero scattering. Hence the clouds which have droplets of water with a>>λ are generally white.
Why are storms black?
Those droplets scatter incoming light from the sun so that only a small fraction of it reaches our eyes. The thicker the cloud, the darker it appears. Clouds with larger water droplets or clouds that are on the taller side scatter even more light and appear even darker.
Why do clouds turn pink?
Excess dust and aerosols suspended in the atmosphere diffuse and scatter light and only the longer wavelength light remains, making the clouds appear pink color or a pinkish-red sky at night.
What are nimbus clouds?
The nimbus clouds are the rain clouds that belong to the category of low-level clouds. The word nimbus in Latin means rainstorm clouds that are found at the lowest altitude of 8000 ft (2400 m), and are usually large grayish-black clouds that cover the entire sky.
Where are nimbus clouds found?
Nimbostratus has a diffuse cloud base generally found anywhere from near surface in the low levels to about 3,000 m (9,800 ft) in the middle level of the troposphere. Although usually dark at its base, it often appears illuminated from within to a surface observer.
What is rain that never reaches the earth?
Sometimes if the air is dry enough at low levels of the atmosphere, it won’t quite reach the surface. The phenomenon that appears instead is called virga. Virga is defined by the National Weather Service as, “streaks or wisps of precipitation falling from a cloud but evaporating before reaching the ground.”
Can it rain without clouds?
Because rain forms when droplets of condensed moisture grow large enough to descend quickly into the air, their absence can make it impossible for rain to occur. That means if there are no clouds overhead, rain cannot happen as well.
What is causing all this rain?
Human-caused climate change intensifies the heaviest downpours. More than 70% of the planet’s surface is water, and as the world warms, more water evaporates from oceans, lakes, and soils. Every 1°F rise also allows the atmosphere to hold 4% more water vapor.
What is the name of the clouds that bring cool dry weather?
In fact, stratus clouds can last for days and bring cool temperatures, persistent rain, drizzle, or even snow.
How do clouds turn GREY?
Basically, clouds look gray when they block out sunlight. A cloud gets thicker as it gathers more water droplets and ice crystals. The thicker a cloud gets, the less light can pass through it. So when you look up at a rain cloud, the base or bottom of it looks gray.
Why is the sky blue while clouds are white?
When sunlight reaches an atmospheric particle in the sky, blue light is scattered away more strongly than other colours, giving the impression that the sky is blue. But in a cloud, sunlight is scattered by much larger water droplets.
Why are storm clouds blue?
The cloud is inherently white/gray (it’s clear water droplets). It’s shadowed from the red light to the west, but exposed to the blue light from the rest of the (apparently mostly clear) sky, so it is mostly illuminated with blue light, and that’s what it will reflect.
What causes a lightning?
In the early stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground. When the opposite charges build up enough, this insulating capacity of the air breaks down and there is a rapid discharge of electricity that we know as lightning.
How dark can storm clouds get?
What does the sky look like before a thunderstorm?
If you’ve watched a thunderstorm during the late afternoon or early evening, you may notice that the sky turns green before it begins to hail. What causes this change in the color of the sky? The effect of the green sky is usually observed with thunderstorms that occur later in the day when the sun angle is lower.
Where does the rain fall?
Where does the rain fall? Answer: Rain falls all around- on field, on tree, on umbrellas and ships.
Why is the sky blue?
The sky is blue due to a phenomenon called Raleigh scattering. This scattering refers to the scattering of electromagnetic radiation (of which light is a form) by particles of a much smaller wavelength.
Why is space dark?
Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there’s virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black. —What color is the sunset on other planets?
What is rain made of?
Rain is liquid precipitation: water falling from the sky. Raindrops fall to Earth when clouds become saturated, or filled, with water droplets. Millions of water droplets bump into each other as they gather in a cloud. When a small water droplet bumps into a bigger one, it condenses, or combines, with the larger one.
Does rain start as snow?
To start off, nearly all precipitation begins as snow. Temperatures are well below freezing where a cloud forms, so when precipitation begins, it often starts as snow. TYPES OF PRECIPITATION: RAIN: defined as water droplets.
Why do clouds float?
The water and ice particles in the clouds we see are simply too small to feel the effects of gravity. As a result, clouds appear to float on air. Clouds are composed primarily of small water droplets and, if it’s cold enough, ice crystals.
Why are nimbus clouds dark?
However, rain clouds are gray instead of white because of their thickness, or height. That is, a cloud gets thicker and denser as it gathers more water droplets and ice crystals — the thicker it gets, the more light it scatters, resulting in less light penetrating all the way through it.
Why are the clouds red at night?
The “red sky” trick gets around this by using the sun. Red wavelengths pass through air more easily than blue ones. When the sun is setting in the west, its light passes through hundreds of miles of atmosphere — becoming extremely red in the process — before hitting the clouds above you.
Are sunsets pollution?
It is often written that natural and manmade dust and pollution cause colorful sunrises and sunsets. Indeed, the brilliant twilight “afterglows” that follow major volcanic eruptions owe their existence to the ejection of small particles high into the atmosphere (more will be said on this a bit later).
Do nimbostratus clouds produce hail?
Cumulonimbus clouds and nimbostratus clouds can also can produce snow, hail, sleet, and other forms of precipitation.
What is this fog?
Fog shows up when water vapor, or water in its gaseous form, condenses. During condensation, molecules of water vapor combine to make tiny liquid water droplets that hang in the air. You can see fog because of these tiny water droplets. Water vapor, a gas, is invisible. Fog happens when it’s very, very humid.
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.
Do cumulonimbus clouds bring thunderstorms?
Cumulonimbus clouds are menacing looking multi-level clouds, extending high into the sky in towers or plumes. More commonly known as thunderclouds, cumulonimbus is the only cloud type that can produce hail, thunder and lightning.
How high up are cumulonimbus clouds?
Cumulonimbus clouds are the kings of all clouds, rising from low altitudes to more than 60,000 feet (20,000 meters) above ground level. They grow due to rising air currents called updrafts, with their tops flattening out into an anvil shape.
What does a virga indicate?
Simply put, virga are trails of precipitation that fall from the underside of a cloud but evaporate or sublime before it can reach the earth’s surface. This happens when falling rain or ice passes through an area of dry or warm air.
Can you see rain from far away?
A precipitation shaft is a weather phenomenon, visible from the ground at large distances from the storm system, as a dark vertical shaft of heavy rain, hail, or snow, generally localized over a relatively small area.
What is virga snow?
Virga is rain (or snow) that evaporates (sublimates) before reaching the ground.
Why is it raining so much in NY?
The reason for the storminess and heavy rain in Upstate New York, meteorologists say, is that we’re caught between the massive heat dome out West and a stubborn high pressure system in the Atlantic Ocean. Those two systems essentially form the sides of a funnel that channels Gulf of Mexico moisture to the Northeast.
Why does Florida rain so much?
Torrential rain in Florida primarily results from the passing of low pressure systems through or close to it. The most well known low pressure system is the tropical hurricane, which is capable of producing truly enormous amounts of precipitation over a short period of time.
Why is it raining so much in Maryland?
Meteorologists say the frequent stretches of rain are the product of frontal boundaries that have remained stubbornly draped over Maryland in recent months. Warm, moist air meets cooler air along those fronts, and when the air is pushed upward, the moisture it carries condenses and falls.
Do white clouds produce rain?
Only clouds that are tall with big water drops can make rain, but they also stop most of the light, which makes them look grey. Read more: Curious Kids: Why do we have bones? There are many different types of clouds, not just white and grey clouds.
What clouds produce tornadoes?
Tornadoes are often accompanied by a wall cloud (murus cloud feature) and are generally associated with large, rotating cumulonimbus clouds known as supercells. Non-supercell thunderstorms can create funnel clouds in the form of landspouts, and when they form over large bodies of water, waterspouts.
What type of clouds bring light rain and fog?
Stratus clouds may produce a light drizzle or a small amount of snow. These clouds are essentially above-ground fog formed either through the lifting of morning fog or through cold air moving at low altitudes over a region.
Why are there no clouds in Arizona?
There’s constantly high air pressure over Arizona because it’s so hot too. Due to the high pressure, air sinks, which means clouds can’t form. Since there’s no rain, there’s no humidity, but that just means the dry air heats up faster without any humidity to absorb heat.
Is lightning possible without clouds?
Some types of lightning, including the most common types, never leave the clouds but travel between differently charged areas within or between clouds. Other rare forms can be sparked by extreme forest fires, volcanic eruptions, and snowstorms.
Can it rain frogs?
Frog rain is a rare meteorological phenomenon in which frogs get swept up in a storm, travel miles and then fall from the sky when the clouds release the water. It doesn’t happen frequently, but it does happen in parts of the world.
