Types of Clouds

There are cirrus clouds, cirrocumulus clouds, cirrostratus clouds, altocumulus clouds, altostratus clouds, cumulus clouds, stratocumulus clouds, stratus clouds, nimbostratus clouds, cumulonimbus clouds, mammatus clouds, enticular clouds.
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.

How Clouds float

Clouds move with the wind. High cirrus clouds are pushed along by the jet stream, sometimes traveling at more than 100 miles-per-hour. When clouds are part of a thunderstorm they travel 40 mph.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.

Cumulus clouds are often described as "puffy" or "cotton-like" in appearance. Cumulus clouds may appear alone, in lines, or in clusters.  
Cumulus clouds are part of the larger category of
cumuliform clouds, which include cumulus, cumulus congestus, and cumulonimbus clouds, and others.  
usaually form in rows with blue sky visible in between them.
Rain rarely occurs with stratus clouds, however, they can turn into nimbostratus clouds.

Nimbostratus clouds form a dark gray, wet looking cloudy layer associated with continuously falling rain or snow. They often produce precipitation that is usually light to moderate.

Mammatus clouds are low hanging bulges that droop from cumulonimbus clouds.

Green Clouds are often associated with severe weather.The green color is not completely understood, but it is thought to have something to do with having a high amount of liquid water drops and hail inside the clouds.

Stratocumulus clouds are low, puffy and gray. Most form in rows with blue sky visible in between them. Rain rarely occurs with stratocumulus clouds, however, they can turn into nimbostratus clouds.

Stratus clouds are uniform grayish clouds that often cover the entire sky.They resemble fog that doesn't reach the ground. Light mist or drizzle sometimes falls out of these clouds. Storm clouds are when clouds get filled with to much water so they release the water,but instead of raining,it pours down.

Altocumulus clouds are mid level clouds that are made of water droplets and appear as gray puffy masses. They usually form in groups. If you see altocumulus clouds on a warm, sticky morning, be prepared to see thunderstorms late in the afternoon.

Altostratus clouds
are gray or blue-gray mid level clouds composed of ice crystals and water droplets. The clouds usually cover the entire sky. In the thinner areas of the clouds, the sun may be dimly visible as a round disk. Altostratus clouds often form ahead of storms with continuous rain or snow.

Cirrocumulus clouds appear as small, rounded white puffs that appear in long rows. The small ripples in the cirrocumulus clouds sometime resemble the scales of a fish. Cirrocumulus clouds are usually seen in the winter and indicate fair, but cold weather.

Cirrostratus clouds are thin, sheet like high clouds that often cover the entire sky. They are so thin that the sun and moon can be seen through them.

Fog is a collection of water droplets or ice crystals suspended in the air at or near the Earth's surface.Fog is a type of stratus cloud.Fog reduces visibility 
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. 

Frozen Fog
Frozen fog is any kind of fog where the droplets have frozen into extremely tiny crystals of ice in midair. Generally this requires temperatures at or below −30 °F,making it common only in and near the Arctic and Antarctic regions.It is most often seen in urban areas.Urban ice fog can become extremely dense and will persist day and night until the temperature rises.

Tropospheric clouds are also known as Nacreous clouds.They can be divided into three main categories.They are too thin tobe seen from the ground.They are most common when strong winds  cross over a long mountain range.
