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.

Does weather move from west to east in the southern hemisphere?

Weather generally in southern hemisphere moves from the west to the east. eg. Weather in Perth AU arrives in Adelaide AU 2 days later and in Sydney AU 5 days later.

There are different circumstances if there is an offshore low or Cyclone off the East coast where sometimes it will move East to West but only until landfall where it dissipates after hitting the Great Dividing Range.

What are the tall puffy kinds of clouds that form by vertical motion in warm and relatively humid air?

The tall puffy clouds that form by vertical motion in warm and humid air are called cumulus clouds. These clouds typically appear isolated, with a flat base and a dome-shaped top. They are often associated with fair weather, but can develop into larger storm clouds if the atmosphere becomes more unstable.

What clouds determine a pending thunderstorm?

Cumulonimbus clouds are the type of clouds that indicate a pending thunderstorm. These clouds are tall, dense, and have an anvil shape at the top. They can produce heavy rain, lightning, thunder, and even hail during a thunderstorm.

What cloud is wispy and forms very high in the sky?

Cirrus clouds are wispy, high-altitude clouds typically found at altitudes above 20,000 feet. These clouds are composed of ice crystals and often indicate fair weather.

Does a tornado need a wall cloud?

No, some tornadoes will form without a wall cloud. In most cases there are of a variety called landspouts, which are tornadoes that do not form in association with the mesocyclone of a supercell. These tornadoes are typically weak, though on occasion have been known to cause damage as high as F3.

What is the name given to a towering cloud that has not fully developed into a thunderstorm?

The name given to a towering cloud that has not fully developed into a thunderstorm is a cumulus congestus cloud. These clouds are large, puffy clouds with vertical growth, indicating instability in the atmosphere.

What do clouds do for nature?

They are a part of the water cycle. After water evaporates (it becomes gas and rises) it condenses into clouds. Once the cloud is large or heavy enough, the gas becomes a liquid again and rain falls.

Why do tornadoes have a spiral shape?

Tornadoes take on a spiral shape because the winds in them spin and move upward. This is because tornadoes originate from the rotating updraft of a supercell thunderstorm. The updraft gets this rotation from wind shear.

Is a cirrocumulus cloud a rain cloud?

No. those clouds are to high to produce precipitation.

What happens when Mumbo Jumbo sees Mingy Jongo in Cloud Cuckooland?

I just did this and it does nothing. Mingy Jongo stays asleep and if you touch him or try and shock him you get hurt and lose life. However, if you die by touching him too much then you will see him wake up and stand as you die.

Why is it bright during a cloudy night?

Even on cloudy nights, some light from the moon and city lights can still filter through the clouds, causing the sky to appear brighter than if it were a completely overcast night. Additionally, the clouds themselves can reflect light back towards the ground, further contributing to the brightness.

What is scatter radiation and film fog?

Scatter radiation is the radiation that is deflected from its original path and interacts with other objects or tissues in the image. This can lead to a decrease in image quality and detail. Film fog refers to unwanted exposure of the film, resulting in a loss of contrast and detail in the image.

Which of the following air results when warm moist meets cold dry air over land?

The warm moist air will be forced to rise over the cold dry air, leading to the formation of clouds and potentially precipitation. This is a common process in the creation of thunderstorms and rain showers.

When warm air expands and rised it creates an area of what?

When warm air expands and rises, it creates an area of low pressure. As the warm air rises, it cools and condenses, forming clouds and potentially leading to the development of thunderstorms or other weather systems.

Will it snow much in winter 2012-2013 in the UK?

It will snow somewhere in the United Kingdom this Winter and I suspect a rather significant amount at high altitude in the Scottish Mountains (i.e the Cairngorm Plateau).

On a more serious note there is evidence to suggest that Northern blocking may become predominant this winter and if high pressure builds around and to the South of Greenland we may get some significant snow falls.

Does sunlight and heat help water enter the atmosphere to form clouds?

As the sun evaporates the water and the water turns into water vapour and rises up. When it reaches a certain height in the atmosphere, the water vapour condenses to form tiny droplets of water and thus forms clouds

How do cumulus clouds form tornadoes?

Cumulus clouds can develop into cumulonimbus clouds, which are usually thunderstorms. All thunderstorms contain an updraft, which is a rising air current. Under the right conditions this updraft can start rotating, becoming a mesocyclone. The thunderstorm is now called a supercell. Sometimes the bottom of the mesocyclone can tighten and intensify to produce a tornado.

Do clouds reflect sun's radiation?

Yes, clouds can reflect incoming solar radiation due to their high albedo, which is the measure of how much sunlight is reflected off a surface. This reflection can have a cooling effect on the Earth's surface by reducing the amount of solar radiation that reaches it.

What is the maximum Water Vapour content in the atmosphere?

The maximum water vapor content that the atmosphere can hold varies with temperature, but under normal conditions, it does not exceed around 4% by volume. This maximum is known as the saturation vapor pressure and is higher in warmer air than in cooler air.

What is the name for cloud seeding compound?

Silver iodide is commonly used as a cloud seeding compound to encourage precipitation in clouds.

Why do your glasses fog up on one side in the morning?

When your glasses fog up in the morning, it's likely due to a temperature difference between your warm skin and the cooler air. Moisture from your skin condenses on the cooler lens surface, causing it to fog up. This effect can be more pronounced on one side if that side is closer to a heat source or if there are uneven air currents hitting your glasses.

What are cloud seeding materials?

Common cloud seeding materials include silver iodide, potassium iodide, and sodium chloride. These materials can help promote the formation of ice crystals in clouds and potentially enhance precipitation.

What are clouds formed by ice crystals?

Clouds formed by ice crystals are typically found at high altitudes where temperatures are below freezing. These clouds, known as cirrus clouds, are wispy and thin in appearance, often indicating fair weather. Ice crystal clouds can also form in mid-level altitudes as altocumulus clouds, showing a mix of ice crystals and water droplets.

Why is harder to run at high altitudes?

At high altitudes, the air pressure is lower which means there is less oxygen available for the body to use during exercise. This can lead to decreased aerobic capacity, making it harder to breathe and for muscles to perform optimally during running. Additionally, the body needs time to acclimatize to the lower oxygen levels at high altitudes.

Can you see beyond the oort cloud?

As of now, we have not observed any objects or phenomena beyond the Oort Cloud. The Oort Cloud is the theoretical boundary of the solar system, so anything beyond it would be in interstellar space. Technology limitations make it difficult to observe objects at such extreme distances.
