As more moist air forms along the surface, the process repeats, resulting in a series of discrete packets of moist air rising to form clouds. [6] This process occurs when one or more of three possible lifting agents—cyclonic/frontal, convective, or orographic—causes air containing invisible water vapor to rise and cool to its dew point, the ...
Clouds in the troposphere assume five physical forms based on structure and process of formation. These forms are commonly used for the purpose of satellite analysis. [ 31 ] They are given below in approximate ascending order of instability or convective activity.
A cap cloud is a special form of the lenticular cloud with a base low enough that it forms around and covers the peak, capping it. [3] A chinook arch cloud is an extensive wave cloud. It has this special name in North America where it is associated with the Chinook wind. It forms above the mountain range, usually at the beginning of a chinook ...
Cloud formation is a complex process that begins with the condensation of water vapor in the atmosphere. This process typically occurs when moist air rises and cools to its dew point, leading to the formation of water droplets or ice crystals. [5]
Mammatus cloud seen at Puthenpeedika, India Mammatus clouds formation in Coimbatore, India Mammatus clouds over the Nepal Himalayas. Mammatus (also called mamma [1] or mammatocumulus, meaning "mammary cloud") is a cellular pattern of pouches hanging underneath the base of a cloud, typically a cumulonimbus raincloud, although they may be attached to other classes of parent clouds.
Scud clouds are a type of cloud formation that are "low, ragged cloud fragments that can sometimes be located near the updraft region of the storm," according to a storm spotting guide from the ...
A typical raindrop is about 2 mm in diameter, a typical cloud droplet is on the order of 0.02 mm, and a typical cloud condensation nucleus is on the order of 0.0001 mm or 0.1 μm or greater in diameter. [1] The number of cloud condensation nuclei in the air can be measured at ranges between around 100 to 1000 per cm 3. [1]
High clouds form in the highest and coldest region of the troposphere from about 5 to 12 km (16,500 to 40,000 ft) in temperate latitudes. [9] [10] At this altitude water almost always freezes so high clouds are generally composed of ice crystals or supercooled water droplets.
