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.

What do you call liquid that changes to gas?

The process of a liquid changing to a gas is called vaporization.

A large temperature lapse rate would occur in a layer with?

A large temperature lapse rate would occur in a layer with rapid changes in temperature over a short vertical distance. This could happen in the troposphere near the Earth's surface, especially in regions with strong convection or temperature inversions.

What does rain fall in?

Drops. Raindrops form in clouds and grow until they can no longer remain suspended. While falling, they are not in the shape of a "teardrop", but rather a sphere which is slightly flattened on the bottom by air resistance.

Why do some clouds pass over without producing any rain?

In order for a cloud to rain it needs enough water molecules to build up. When the water molecules condense enough together they make the clouds heavy and therfore drop water. So clouds that don't rain at the time probably will eventually.

What are the four factors that interact to cause weather?

  • What is at least one type of factor's is the air pressure that is pulling down on the evaporation on the ground , do that the sky's are nice and clear and bright so know water droplet's goes in the atmosphere, so cloud's don't make any condensation

What is the halo that is around the sun at 45 degrees from the sun?

This could be one of a couple of halo phenomena, with one much rarer than the others. Two arcs that form at this distance from the sun are the 46-degrees halo and the supralateralarc. Both are quite rare and they are difficult to distinguish at times, although they are caused by different types of ice crystals in the atmosphere.

The 46-degrees halo, the rarer of the two, is formed when light is refracted by randomly-aligned ice crystals. These crystals are usually hexagonal prisms, with two hexagonal end faces and six rectangular side faces. The supralateral arc forms when light is refracted by crystals falling so that their side faces are horizontal.

Distinguishing between the two can be tricky, as they both form at about the same distance from the sun. However, some features can be used to tell them apart:

If the sun is higher than 32 degrees, a supralateral arc cannot form, so it must be a 46-degrees halo.

If a circumzenithal arc is present (a bright arc directly overhead), this can be useful - a supralateral arc alwaystouches the circumzenithal arc, so if there is no overlap, it is a 46-degrees halo.

Supralateral arcs are brightest at the top, whereas 46-degrees halos are uniformly bright - variations in clouds can be misleading, though.

Supralateral arcs often display a better distinction of blue and green colours (although this is not a reliable indicator).

What type of clouds produce most thunderstorms?

Cumulonimbus clouds are responsible for producing most thunderstorms. These large, towering clouds are capable of generating intense updrafts and downdrafts, leading to the formation of lightning, thunder, and heavy rainfall.

What is the ideal relative humidity for a basement in Ohio?

For any interiors the ideal relative humidity is between 30% to 50%. More than 50% causes growth of bacteria/fungi/mould. Less than 30% will cause health problems skin cracks other health issues.

When a rock falls from the sky, it hits the ground much faster than a feather or leaf would...partly because of it's higher weight and density, and partly because of its shape slowing itself down. Well...the water molecules that individually comprise a cloud don't fall to the ground that quickly either (which is why they look like they're floating)...Sometimes clouds ARE falling to the ground, but only at a speed of 0.0003 feet per second

A gas is most likely to change to the liquid phase when the pressure on the gas?

A gas is most likely to change to the liquid phase when the pressure on the gas is increased. This is because the same number of molecules will have less space to occupy.

When the cloud pass over hills or mountains what do they drop?

When clouds pass over hills or mountains, they can drop precipitation in the form of rain or snow. As the air rises over the elevated terrain, it cools and condenses, leading to the formation of clouds and eventually precipitation. This process is known as orographic lift.

Why the sky changes color at sunset?

During sunset, sunlight passes through more of the Earth's atmosphere, scattering shorter wavelengths like blue and violet, leaving longer wavelengths like red and orange to dominate the sky. This scattering effect causes the sky to change color as the sun sets.

Which of the following occurs as water vapor cools in the atmosphere?

Condensation occurs as water vapor cools in the atmosphere, leading to the formation of clouds or fog.

How much Water in fog over a city block?

The amount of water in fog over a city block can vary widely depending on factors like temperature, humidity, and fog density. However, on average, fog can contain around 0.05 to 0.5 grams of water per cubic meter. This means that over a city block, which can cover an area of 10,000 to 20,000 square meters, there could be between 500 to 10,000 grams (or 0.5 to 10 kilograms) of water in the fog.

What does air do in a high pressure area?

In a high pressure area, air molecules are densely packed together, causing the air to sink and compress. This leads to stable weather conditions with clear skies and minimal cloud formation. High pressure systems are often associated with fair weather.

If a low pressure system follows a typical storm track across new york state it will move toward?

It will move toward the North East.

When does fog form in inlets and bays?

Fog in inlets and bays tends to form when warm air moves over cooler water, causing the air to cool and reach its dew point, leading to condensation and the formation of fog. This commonly occurs during the early morning or evening when the temperature difference between the air and water is greatest.

What latitudes cause warm air masses in summer and cold ones in winter?

Low latitudes, closer to the equator, tend to have warm air masses in summer due to more direct sunlight and high temperatures. High latitudes, closer to the poles, tend to have cold air masses in winter due to limited sunlight and low temperatures.

Is wind formed by air masses that meet?

Wind is primarily formed by differences in air pressure caused by the uneven heating of the Earth's surface by the sun. When air masses of different temperatures and densities meet, these pressure differences lead to the movement of air, creating wind.

Air has more capacity to hold water at what?

Air has more capacity to hold water when the air is warmer. The colder the air is, the less water it can hold.

When warm air rises and cool air sinks what current is created?

When warm air rises and cool air sinks, a convection current is created. This is due to the difference in air density caused by temperature variations. Warm air is less dense and rises, while cool air is denser and sinks, creating a circular flow of air.

Localwho was the man with the black cloud over him in lil abner?

The man with the black cloud over him in "Li'l Abner" is Joe Btfsplk. He is a character who brings bad luck to everyone around him, and wherever he goes, a rain cloud follows him, symbolizing his misfortune.

A cloud is a dense visible mass of?

A cloud is a dense visible mass of suspended water droplets or ice crystals in the atmosphere.
