Cirrus clouds are often seen during fair weather. ![]() They are commonly known as 'mare's tails' because they are shaped like the tail of a horse. ( Geophysical Research Letters, doi:10.1002/2015GL066795, 2015)Ĭitation: Stanley, S. Cirrus clouds are made of ice crystals and look like long, thin, wispy white streamers high in the sky. ![]() Meanwhile, the researchers call for more modeling studies to explore its potential effects. Still, cirrus cloud thinning is a very new idea, and it is uncertain whether the technique is even feasible. It studied the impact of human-produced air pollution on greenhouse gases and on chemically reactive gases in the atmosphere. The Atmospheric Tomography Mission (ATom) was a NASA Earth Venture Suborbital-2 mission. This would keep precipitation up in regions that are prone to drought. These data have been applied to better understand the role of mineral dust in cirrus cloud formation. Found at the same altitude as their cirrus and cirrocumulus counterparts, these clouds are more widely known. Cirrostratus clouds can best be described as a cloud blanket high up in the troposphere, spread out across the sky. ![]() The team found that unlike other radiation management techniques, cirrus cloud thinning could potentially alleviate the disruption of the water cycle while keeping global temperatures down. Definition: Thin, transparent, high-altitude cloud layer capable of producing a 22° halo. This would allow more longwave radiation to escape from the atmosphere into space. In the real world, scientists would thin out cirrus clouds by using aircraft to seed the cloud formation regions-where the icy wisps form-with small particles to reduce the clouds’ thickness and lifetime. Cirrus (cloud classification symbol: Ci) is a genus of atmospheric cloud generally characterized by thin, wispy strands, giving the type its name from the Latin word cirrus meaning a ringlet or curling lock of hair.12 The strands of cloud sometimes appear in tufts of a distinctive form referred to by the common name of 'mares. Our patented, proven technology solutions will enable you to start using your new storage technology up to 90 sooner. Cirrus Data has successfully completed block-level data migrations for over 500 organizations worldwide. The researchers used a global climate model to simulate the effects of cirrus cloud thinning. Cloud, hybrid, on-premise, vendor agnostic: you can migrate your data securely, with no business disruption. examined the effects of so-called cirrus cloud thinning to find out if the technique could avoid some of the problems that might accompany other radiation management approaches, including suppression of the water cycle. Understanding how climate engineering techniques might affect the water cycle is important for evaluating their potential usefulness. The best part about all of our plans They come with our enhanced local support from migration to helpdesk support, weve got you. Evidence suggests that climate change is already affecting the global water cycle low-latitude and midlatitude land regions could see increased droughts in the future, whereas global precipitation will increase overall. Along those same lines, a newer approach proposes disrupting the formation of cirrus clouds-the thin, wispy clouds found above 20,000 feet-to let out more longwave radiation that would otherwise remain trapped in the atmosphere.Įarlier climate model studies found that radiation management can suppress the water cycle, reducing rainfall and causing droughts in vulnerable regions throughout the world. Some proposed projects involve reflecting incoming solar radiation back into space, keeping it from warming the atmosphere. Often however, they mark the high-altitude front of an approaching depression, with rain from low-altitude stratus clouds following with 12 hours.Sign up now Source: Geophysical Research LettersĪs climate change progresses, researchers are exploring climate engineering methods to slow it down or lessen its extent. Cirrus generally occur in fair weather and point in the direction of air movement at their elevation. Typically found at heights greater than 20,000 feet (6,000 meters), cirrus clouds are composed of ice crystals that originate from the freezing of supercooled water droplets. The most common form of high-level clouds are thin and often wispy cirrus clouds. High-level clouds are typically thin and white in appearance, but can appear in a magnificent array of colours when the Sun is low on the horizon. High-level clouds form above 20,000 feet (6,000 meters) and since the temperatures are so cold at such high elevations, these clouds are primarily composed of ice crystals.
