WebWispy cirrus clouds, which are made of ice crystals, occur only at higher altitudes. On a typical day and at altitudes less than 11 km , the temperature at an altitude y is given by T=T0−αy , where T0 = 30.0 ∘C and α= (6.00∘C)/ (1000m). Find the altitude y … Cirrus (cloud classification symbol: Ci) is a genus of high cloud made of ice crystals. Cirrus clouds typically appear delicate and wispy with white strands. Cirrus are usually formed when warm, dry air rises, causing water vapor deposition onto rocky or metallic dust particles at high altitudes. Globally, they form … See more Cirrus are wispy clouds made of long strands of ice crystals that are described as feathery, hair-like, or layered in appearance. First defined scientifically by Luke Howard in an 1803 paper, their name is derived from the See more Random, isolated cirrus do not have any particular significance. A large number of cirrus clouds can be a sign of an approaching frontal system or upper air disturbance. The … See more Scientists have studied the properties of cirrus using several different methods. Lidar (laser-based radar) gives highly accurate information on the cloud's altitude, length, and … See more Cirrus clouds are one of three different genera of high-level clouds, all of which are given the prefix "cirro-". The other two genera are cirrocumulus and cirrostratus. High-level clouds usually form above 6,100 m (20,000 ft). Cirrocumulus and cirrostratus are … See more Cirrus clouds are usually formed as warm, dry air rises, causing water vapor to undergo deposition onto rocky or metallic dust particles at high altitudes. The average cirrus cloud altitude increases as latitude decreases, but the altitude is always capped by the See more Cirrus clouds cover up to 25% of the Earth (up to 70% in the tropics at night ) and have a net heating effect. When they are thin and translucent, the clouds efficiently absorb outgoing infrared radiation while only marginally reflecting the incoming sunlight. When … See more Cirrus clouds can produce several optical effects like halos around the Sun and Moon. Halos are caused by interaction of the light with hexagonal ice crystals present in the clouds which, depending on their shape and orientation, can result in a wide variety of white … See more

Cirrus clouds are thin, wispy clouds that are often seen in the sky in a streaky pattern. They are made up of ice crystals and are typically very high in the atmosphere. Cirrus clouds can indicate fair weather, as they are often found in strong high pressure systems. smart ass instructions

Web3.1.6.2 Ice Clouds Ice clouds, also called cirrus clouds, are made up of ice crystals and start to form at altitudes of 5.5 km in temperate regions and of 6.5 km in tropical regions, making them the highest clouds in the troposphere. A small seed particle, or INP, is needed for heterogeneous ice nucleation. WebComposed of ice crystals, cirro-form clouds are whitish and hair-like. There are the high, wispy clouds to first appear in advance of a low-pressure area such as a mid-latitude storm system or a tropical system such as a … WebFeb 24, 2024 · Cirrus clouds: Cirrus clouds are high-level clouds that are thin, wispy, and made up of ice crystals. They are often white or gray and are often a sign of a change in weather. Nimbus clouds: Nimbus clouds are classified as low-level clouds, typically below 6,500 feet, and are composed of water droplets. These are your storm clouds. smart ass humor
