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.

Ice crystals that fall from the sky-?

Ice crystals falling from the sky are not branched like snowflakes, but tend to be more needle-like. They weigh less than snowflakes, and therefore can seem almost suspended in the air. They often cause strange optical illusions as light reflects off them; at night, light appears to shoot straight up into the sky like a pillar. They are also responsible for "sun dogs", the rainbow like bars that can appear on either side of the sun.

What is fluffy Cotton like clouds called?

"Fluffy cotton-like clouds are called cumulus clouds."

Which layer does hail occur?

Hail typically forms in the troposphere, which is the lowest layer of Earth's atmosphere. Specifically, it forms in the region of the troposphere where thunderstorms develop, typically between 6,500 to 16,500 feet above the ground.

How the water droplets appear on the underside of the cover?

Water droplets form on the underside of a cover due to condensation. When warm, moist air comes into contact with a cooler surface, such as a cover exposed to the elements, the air cools down and reaches its dew point, causing water vapor to condense into liquid water droplets.

What is cloud called at ground level?

Cloud at ground level is called fog. It forms when the air near the ground becomes cooled to the point where it can no longer hold its moisture in a vapor state, causing it to condense into tiny water droplets.

Do clouds have a definite volume?

Given a sufficiently rigorous definition for "cloud" and at a particular point in time, yes.

However, it's not necessarily constant, and determining exactly what what it is at any given moment could be extremely difficult.

What type of clouds is called fair weather clouds and looks like floating cotton?

Cumulus clouds are often referred to as fair weather clouds and have a fluffy, cotton-like appearance. They are typically associated with stable weather conditions and are common on calm, sunny days.

A low-level cloud that often produces fog and drizzle is called?

A low-level cloud that often produces fog and drizzle is called a stratus cloud. Stratus clouds are characterized by their flat and layered appearance, covering the sky like a blanket. They are typically found below 6,500 feet and are associated with stable weather conditions.

Do clouds cover the sun at night?

No and yes in the same time because if the sun didnt evaporate water in day time for example it was foggy or something the air won't rise and there will be no clouds but in other cases it was sunny in daytime we would get clouds at night

How does water enters the air?

Water vapor enters the air as water at the surface evaporates or as plants transpire water vapor from their leaves.

Why do vegetables create water droplets?

This is most likely perspiration. Perspiration occurs when excess water from the plant is evaporated by the heat or light, and is carried into the air, but since the produce is bagged, the only place the water can go is on the top of the bag, which is why the water droplets form there.

Does a gas dissolves in a liquid most rapidly when under low pressure?

Yes, a gas dissolves in a liquid more rapidly under low pressure because there is a concentration gradient favoring the movement of gas into the liquid. Lower pressure reduces the amount of gas above the liquid, allowing more gas molecules to dissolve.

What type of heat energy occurs when warm air rises and cool air falls?

Are you asking about heat transfer or latent heat? As warm air rises, decreasing air pressure will allow moisture present to cool and condense. Once condensation occurs, latent heat , or the energy hidden within water molecules, is released. This is an example of adiabatic cooling, by air pressure change alone. As that same parcel of air falls, air pressure will compress the air (adiabatically) and warm it. As the falling air warms, its ability to hold moisture increases.

When was Nimbus Communications Limited created?

Nimbus Communications Limited was created in 1997.

When was RM Nimbus created?

The RM Nimbus series of computers was first introduced in 1985. It was a range of desktop computers developed by Research Machines, a British computer company.

When was Bouncing off Clouds created?

"Bouncing off Clouds" by Tori Amos was released in 2007 as part of her album "American Doll Posse."

Does warm air rise because of density?

Yes..Low density rises. As the particle gain more kinetic energy from being heated the density decreases as the particles move further apart causing a lower density. This could then form a convenction current but that is a different topic!

What is water vapor in clouds called?

This is known as the "humidity" of the air. Warmer air can hold more water than colder air.

The percentage of water vapor in the air, compared to the maximum amount possible at that temperature, is called the relative humidity.

Air that contains 100% of the possible water vapor is said to be saturated. In some cases, more water is added to the air, causing it to become supersaturated (relative humidity over 100%).

What causes clouds to reflect sunlight back to space?

Clouds reflect sunlight back to space due to their high albedo, or reflectivity. This happens because clouds are made up of tiny water droplets or ice crystals that scatter incoming sunlight. The more dense and widespread the clouds, the more sunlight they can reflect back into space.

Can low cumulonimbus clouds bring both thunderstorms and tornadoes?

Low-topped cumulonimbus clouds can easily bring thunderstorms. Tornadoes are less likely than in a high-topped storm, but are still possible.

If you are referring to cumulonimbus clouds with a low base, then yes. In fact, tornadoes develop mor easily in low-based storms.

What clouds are thunderstorms and tornadoes associated with?

Thunderstorms and tornadoes are typically associated with cumulonimbus clouds, also known as thunderstorm clouds. These clouds are vertically developed and can produce severe weather conditions due to the strong updrafts and downdrafts that exist within them.

What is the refractive index of fog?

Fog is made out of water droplets in suspension in the air. The refractive index of these droplets is 1.3330. However the body of fog as seen on mass is opaque (enough of it will stop light) and opaque substances do not have a refractive index.

When was Nimbus Sans created?

Nimbus Sans was created in 1987 by the company URW (Underware Ready-made / Altsys Library). It is a typeface that is commonly used for digital applications and is known for its clean and modern design.

When was Blanket of Fog created?

Blanket of Fog was created in 1998.
