Clouds
A cloud is a visible body of very fine water droplets or ice particles suspended in the atmosphere at altitudes up to several miles above sea level. They are generally produced by the condensation of water vapor. Other clouds, less commonly seen, are composed of smokes or dusts.

How much precipitation do cumulus clouds produce?
Cumulus clouds can produce varying amounts of precipitation, typically in the form of rain showers. The amount of precipitation produced by cumulus clouds depends on factors such as the size and vertical development of the cloud, atmospheric conditions, and location.
What types of clouds are in a tornado?
Tornadoes are associated with cumulonimbus clouds, which are large, dense, and vertically developed clouds that can produce severe weather. These clouds have strong updrafts that can lead to the formation of tornadoes when conditions are conducive.
Is water heated from water vapour?
Water is typically heated from a liquid state, not from water vapor. Water vapor forms when liquid water is heated to its boiling point and evaporates into the air. To heat water using water vapor, one would need to first condense the vapor back into liquid water before further heating it.
What type of clouds form winds?
Wind is caused by air flowing from high pressure to low pressure. Since the Earth is rotating, however, the air does not flow directly from high to low pressure, but it is deflected to the right (in the Northern Hemisphere; to the left in the Southern Hemisphere), so that the wind flows mostly around the high and low pressure areas.
This effect of the wind "feeling the Earth turn underneath it" is important for very large and long-lived pressure systems. For small, short-lived systems (such as in the cold outflow of a thunderstorm) the wind will flow directly from high pressure to low pressure.
The closer the high and low pressure areas are together, the stronger the "pressure gradient", and the stronger the winds. On weather maps, lines of constant pressure are drawn (as in the example, above) which are called "isobars". These isobars are usually labeled with their pressure value in millibars (mb). The closer these lines are together, the stronger the wind.
Clouds do not form winds.
The curvature of the isobars is also important to the wind speed. Given the same pressure gradient (isobar spacing), if the isobars are curved anticyclonically (around the high pressure in the above example) the wind will be stronger. If the isobars are curved cyclonically (around the low pressure in the example above) the wind will be weaker.
Near the surface of the Earth, friction from the ground slows the wind down. During the day, when convective mixing is stirring up the lower atmosphere, this effect is minimized. At night, however, when convective mixing has stopped, the surface wind can slow considerably, or even stop altogether.
Wind can be thought of one way that the atmosphere moves excess heat around. Directly or indirectly, wind forms for the promary purpose of helping to transport excess heat either away from the surface of the Earth, where sunlight causes an excess of energy buildup, or from warm regions (usually the tropics) to cooler regions (usually the higher latitudes).
Extratropical cyclones accomplish much of this heat transport outside of the tropics, while in the tropics the trade winds, monsoons, and hurricanes transport much of the heat.
Is air thickest near the ground?
no mid air in the sky says the scientist from steefal areobotics
New answer. I'm not sure who the scientist from steefal areobotics is or where he got his information but the air is thinner the higher you go in altitude. At sea level the atmospheric pressure is 14.7psi and as you increase the altitude the air pressure becomes less and less. There is 78%nitrogen, 21%oxygen and 1% other inert gases in the atmosphere and that reamins constant but as the air thins out the gases are spread farther apart making the air thinner. When you go up in a jetliner you wouldn't be able to breathe without having the aircraft cabin pressurized. They pressurize the cabin to about the same atmospheric pressure as you would find at 8000 feet and that allows you to breathe without having to add oxygen.
Fog is a type of low-lying cloud that forms when moist air near the ground cools down to the point where it can no longer hold its moisture in vapor form. This causes the water vapor to condense into tiny droplets, forming the visible mist characteristic of fog.
What takes photos from space of clouds and storm systems?
Satellites equipped with cameras and sensors that capture images of Earth from space take photos of clouds and storm systems. These satellites are part of different space agencies and organizations around the world. The images captured are used for weather forecasting, climate monitoring, and scientific research.
What does the relative humidity have to be far a cloud to form?
Clouds can form at any relative humidity level, but typically they form when the relative humidity is close to 100%. This is when the air is nearly saturated with water vapor and begins to condense into liquid droplets, forming a cloud.
What types of clousd are wispy?
Cirrus clouds are wispy and thin, made of ice crystals at high altitudes. These clouds often have a feathery appearance and are commonly seen in fair weather conditions.
How do cloud droplets become large enough to fall as precipitation?
Cloud droplets grow in size through a process called coalescence, where smaller droplets collide and merge together to form larger droplets. Once the droplets reach a size that gravity can overcome air resistance, they fall as precipitation. Additionally, the presence of ice crystals in clouds can lead to the formation of snowflakes that eventually fall as snow.
At what condition will water vapor behave most ideally?
Water vapor will behave most ideally at low pressures and high temperatures. This is because at these conditions, water molecules are far apart and have higher kinetic energy, resulting in less intermolecular interactions.
Because as my earth science teacher always told me "Warm wet air rises"
It's a density related matter, and as clouds are less dense than air, they float in the sky rather than falling down.
More: Think about this: Liquid helium doesn't fall up and splash on the ceiling.
Clouds are LIGHTER than air, and the barometer indicates LESS air pressure on a cloudy day because of that.
Water vapor is H2O which is Half the mass of air molecules (N2 and O2) because it has only one O (and two hydrogens which are even lighter than one helium atom).
Clouds are not liquid, and you can't swim or drown in them, unless they become liquid and then a lot of Rain falls down.
Clouds are not solid, and you can't walk on them, but if it snows, the snow may be something like 10 times deeper than if it had rained.
Clouds are volumes of relatively concentrated water vapor.
A volume of water vapor weighs only half of what a volume of air does.
Water is common but strange stuff, because as a liquid it is heaver and denser than it should be, and when its a gas or a solid, it is a lot lighter and less dense than it should be, and that's not obvious.
Well because they have already fallen down and are lying on the ground. Due to the vertically changing air pressure, temperature and water density the lower cloud part is mainly transparent( and therefore invisible ) and the top part like a fog respectively. The higher cloud part is transparent again.
If some piece of foggy cloud descended and crossed the bottom boundary of the visible cloud, the environmental conditions ( mainly the pressure ) let this cloud piece to transform to invisible vapour and vise versa.
Sometimes for the same reason there is a pack of bigger number the transparent and nontransparent layers -- so called multilayer clouds. Due to the approximately exponentially falling air pressure with the height the bottom boundary of visible clouds seems often to be more flat ( plain ) in comparison with the top cloud boundary.
Seeding is not always necessary, but it can help improve the growth and health of plants by establishing a strong root system early on. Seeding can also aid in preventing erosion, improving soil quality, and restoring ecosystems in certain environments. Ultimately, the decision to seed depends on the specific goals and conditions of the area being considered.
How do you prevent fog in an scba mask?
To prevent fogging in an SCBA mask, you can apply an anti-fog solution specifically designed for the mask's lens. Additionally, ensure a proper seal on the mask to prevent warm exhaled air from infiltrating and causing condensation. Regularly cleaning the mask with a mild soap solution can also help maintain clarity.
Not technically. It is the beginning of a tornado, but they are categorized differently.
It is not considered a tornado until it reaches the ground with damaging winds.
What do white clouds symbolize?
White clouds are often seen as symbols of purity, peace, and clarity. They can represent freedom, tranquility, and a sense of lightness or simplicity. In some cultures, white clouds also symbolize spirituality, divine presence, or a higher realm of consciousness.
What is call when there is a lot of water vapor in the air?
When there is a lot of water vapor in the air, it is known as high humidity. This can make the air feel sticky and heavy, and may contribute to feelings of discomfort or difficulty breathing for some individuals. High humidity levels can also lead to increased likelihood of precipitation or fog formation.
What most occur for rain to fall from a cloud?
Clouds are really water vapor and when water vapor gets heavy, water just drips down to the ground, causing rain fall.
Cumulus and nimbus clouds hold water in the form of water droplets or ice crystals. These clouds are typically associated with precipitation and can release water in the form of rain, snow, or hail.
What whether does a cirrus cloud bring?
Cirrus clouds typically indicate fair weather. They are thin and wispy clouds found at high altitudes, and often appear as strands or patches across the sky. While they don't usually bring precipitation, their presence can sometimes signal a change in the weather ahead.
What cloud is wispy feathery looking cloud that forms above six-thousand meters?
The cloud that forms above six-thousand meters is likely cirrus clouds. Cirrus clouds are thin, wispy clouds that form at high altitudes and are composed of ice crystals. They often indicate fair weather but can also signal a change in the weather.
Why do cold fronts produce hail and tornadoes?
A cold front occurs when a mass of relatively cool or cold air plows into a mass of warmer air. The warmer hair gets force upwards because it is less dense. As it rises it expands and cools and the moisture in it condenses, producing rain and thunderstorms.
Sometimes these storms are strong enough to produce hail and tornadoes
How did the sky get its color?
The sky appears blue during the day because molecules in the air scatter sunlight in all directions. This scattering of shorter wavelength light - like blue and violet – is more prevalent, which gives the sky its blue color. At sunrise and sunset, the sky appears orange or red because the sunlight has to pass through more of Earth's atmosphere, scattering the blue and violet light and leaving the longer wavelength red and orange light dominate.
What kind of clouds often bring drizzle?
Stratus clouds are often associated with drizzle. These low-level clouds form a uniform layer and are known for their ability to produce light precipitation like drizzle or light rain.
Are clouds made of gas and dust?
Clouds are primarily made up of water droplets or ice crystals, not gas and dust. Water vapor in the atmosphere condenses into tiny water droplets or ice crystals, which then come together to form clouds. Dust and other particles can also contribute to cloud formation by serving as nuclei around which water vapor can condense.
