Cloud
« on: March 13, 2012, 08:06:18 PM »
Cloud : Cloud is formed as a result of condensation of water vapor present in the air. When air is cooled below its dew point the excess water vapor condenses out as visible water droplets. If the condensation occurs near the ground level it takes the form of dew, mist or fog. When condensation occurs above the ground level it takes the form of cloud. Clouds are mainly of 10 types. I m just discussing low clouds as these kinds of clouds will mostly be available in upcoming days.
Low level clouds :
Stratus Cloud  (St) :  A uniform layer of cloud resembling fog, but not resting on the ground.
Stratocumulus (Sc) :  This kind of cloud are usually grey with darker parts.
Nimbostratus (Ns) :  A dense layer of dark grey colony and nearly uniform appearance and of great vertical thickness; it usually gives precipitation rain, sleet or snow.
Clouds with vertical development:
Cumulus (Cu) :   Thick clouds with vertical development; the upper surface is dome shaped and exhibits pro-turbulence while the base is nearly horizontal
Cumulonimbus (Cb) :   Cumulonimbus clouds are clouds of vertical development. These clouds are found in weather like hail, strong winds and thunder storms. They can go up to 6,000 meters from the grown or maybe even bigger. The flat top, also known as the “anvil top” is white but the base is not. When these clouds are in a line it is called a squall line. Most of cumulonimbus clouds are made of water droplets and as you go up to the top, it get colder. Some may be formed by ice crystals though. When the clouds are cumulus, they may form into cumulonimbus clouds. This types of cloud is very dangerous. Lots of lightening may take place from this cloud.
I hope these little information’s will help all of you to have an idea about the cloud and to take necessary measures accordingly……. 
