How does clouds work




















Clouds are made up of tiny water droplets or ice crystals, usually a mixture of both. The water and ice scatter all light, making clouds appear white. If the clouds get thick enough or high enough all the light above does not make it through, hence the gray or dark look.

Also, if there are lots of other clouds around, their shadow can add to the gray or multicolored gray appearance. Why do clouds float? A cloud is made up of liquid water droplets. A cloud forms when air is heated by the sun. As it rises, it slowly cools it reaches the saturation point and water condenses, forming a cloud. As long as the cloud and the air that its made of is warmer than the outside air around it, it floats!

How do clouds move? Clouds move with the wind. High cirrus clouds are pushed along by the jet stream, sometimes traveling at more than miles-per-hour. When clouds are part of a thunderstorm they usually travel at 30 to 40 mph. W hy do clouds form at different heights in the atmosphere? The characteristics of clouds are dictated by the elements available, including the amount of water vapor, the temperatures at that height, the wind, and the interplay of other air masses.

How is fog formed? There are many different types of fog, but fog is mostly formed when southerly winds bring warm, moist air into a region, possibly ending a cold outbreak. As the warm, moist air flows over much colder soil or snow, dense fog often forms. Warm, moist air is cooled from below as it flows over a colder surface. If the air is near saturation, moisture will condense out of the cooled air and form fog.

With light winds, the fog near the ground can become thick and reduce visibility to zero. They are composed of ice and are thin, wispy clouds blown in high winds into long streamers.

Cirrus clouds are usually white and predict fair to pleasant weather. By watching the movement of cirrus clouds you can tell from which direction weather is approaching.

When you see cirrus clouds, it usually indicates that a change in the weather will occur within 24 hours. Common price models include monthly or yearly rates, depending on the services you are using. Other cloud based services include cloud hosting and servers, offered by companies such as Rackspace. You can see PaaS in action with the Fastmetrics cloud phone service, which offers a cloud PBX phone system , hosted securely in the cloud.

Another example is this server for free video conference calls , for anyone from anywhere, without the use of software.

To understand the workings of a cloud system, it is easier to divide it into two sections: the front end and the back end. They are connected to each other through a network, usually the Internet. The front end is the side of the computer user or client.

Also the application essential to access the cloud system. It is not necessary that all cloud computing systems have the same user interface. On the back end of the cloud technology system, there are various computers, servers and data storage systems that make up the cloud.

A cloud computing system could potentially include any computer program, from data processing to video games. But how does the water and ice that makes up clouds get into the sky?

And why do different types of clouds form? The water or ice that make up clouds travels into the sky within air as water vapor, the gas form of water. Water vapor gets into air mainly by evaporation — some of the liquid water from the ocean, lakes, and rivers turns into water vapor and travels in the air.

When air rises in the atmosphere it gets cooler and is under less pressure. The vapor becomes small water droplets or ice crystals and a cloud is formed. These particles, such as dust and pollen, are called condensation nuclei. He offers a fuller answer: "Most clouds form in rising air.

As a volume, or parcel, of air rises, it expands and cools. In addition, the relative humidity of the rising air increases. As the parcel approaches the point of saturation, water vapor condenses to form tiny water droplets or ice particles, creating a cloud. Saturation occurs at a distinct altitude, which varies depending on the temperature and humidity structure of the atmosphere.

Below this condensation level clouds do not form; this cutoff explains why cloud bases have a distinct appearance and are usually flat. Some clouds are more diffuse at their edges than others.

How sharp the cloud edges appear depends on the type of cloud, the humidity of the surrounding clear air and how close you are to the cloud. In this system, there are two fundamental cloud structures layered or convective and two basic compositions water droplets or ice particles. The categories also include clouds that are precipitating. Stratus or layered clouds do have the appearance of fog. Cumulus clouds, the upper parts of which resemble cauliflower, are a type of convective cloud.

These clouds form in rapidly rising air and are composed of many small water droplets. The small drops scatter light effectively and make the cloud appear bright. Likewise, if you smash up glass and separate the small pieces from the large, the grouping of small pieces will appear brighter.

As a result, the cloud's boundaries appear sharp. In contrast is the cirrus uncinus, a type of ice cloud that resembles a comma.
