The Intergovernmental Panel on Climate Change. (4) They can detect water vapor, which is invisible to the eye. the long term prevailing weather conditions at a particular place based upon records taken, distance from the equator measured in degrees north or south of the equator, the short term periodic change in the location of warm and cold water masses in the Pacific Ocean, the water in the eastern Pacific Ocean is cooler than usual, an area in the stratosphere where ozone is highly concentrated, a class of human-made chemicals that scientists thought were damaging the ozone layer, a thinning of stratospheric ozone that occurs over the poles during the spring, high-altitude clouds made of water and nitric acid that form when temperatures fall below about -80 degrees C, increase in the average temperature of earth's surface, requires developed countries to decrease emissions of carbon dioxide and other greenhouse gases by an average of 5 percent below their 1990 levels by 2012. Log in Sign up. Polar stratospheric clouds form at very high altitudes in polar regions of the stratosphere. Arctic ozone decreases of as much as 40 percent have been measured. Though CFC production has been curtailed, the threat to upper atmospheric ozone continues because CFCs. Observations of polar stratospheric clouds (PSCs) date back to the end of the 19th century. PLAY. The clouds can also be associated with very high surface winds, which may indicate the presence of, or induce, winds and waves in the stratosphere. The Polar Stratospheric Clouds that form during the polar winter in the stratosphere, altitudes of 15,000 to 25,000 meters. A thinning of stratospheric ozone that occurs over the poles during the spring. A multitude of feedbacks also occurred in the models due to the polar stratospheric clouds' presence. Polar stratospheric clouds at about 80,000 feet altitude. The particles that form typically consist of a mixture of water and nitric acid (HNO3). This photograph shows polar stratospheric clouds lit from below near Kiruna, Sweden. NASA’s Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite was in the right place at the right time in early 2011. ə s /, from nacre, or mother of pearl, due to its iridescence), are clouds in the winter polar stratosphere at altitudes of 15,000–25,000 meters (49,000–82,000 ft). Polar stratospheric clouds only form in temps -78C. Search. Arctic ozone decreases of as much as 40 percent have been measured. I've gotten into polar stratospheric cloud formations, and I'm not quite sure how they are formed. The distance from the equator measured in degrees north or south of the equator. Greenhouse Effect . 11 terms. diff of the 2 C-O stretching coordinates; one C-O bond length increases while the other decreases. These reactions lead to the production of free radicals of chlorine in the stratosphere which directly destroy ozone molecules. C22-Polar Vortex-Ozone Hole-Ozone Depletion-Polar Stratospheric Clouds - Geography, Environment - Duration: 17:49. In this visualization, sequential temperature readings taken in the research area for SOLVE (Stratospheric Ozone Loss and Validation Experiment) are plotted against a threshold temperature for PSC formation. I want to know the origin of nitric acid or the sulfuric acid within these clouds. Yet, these inclusions of Nitric or Surffic acids, are they from human activities? Water is cooler than usual in the eastern Pacific Ocean. As a consequence, Arctic stratospheric air is generally much warmer than in the Antarctic, and fewer clouds form there. The clouds … Test. PSCs provide surfaces upon which heterogeneous chemical reactions take place. A polar winter vortex also forms in the Northern Hemisphere. Should the temperature rise, clouds won't form. Global Warming & Stratospheric Ozone Exam. high-altitude clouds made of water and nitric acid that form when temperatures fall below about -80 degrees C Winds push warm water eastward in the Pacific Ocean. Phytoplankton, Tropical Rain Forests, and Oceans. International agreement to limit CFC production. Subscribe to our newsletters Image. Image of the Day Atmosphere. La Nina is the _______ phase of the El Nino-Southern Oscillation (ENSO) cycle. PSCs appear in the lower stratosphere near the poles in winter. When temperatures fall below about -80 degrees, high-altitude clouds made of water and nitric acid begin to form. Latitude strongly influences climate because _______ solar energy falls on areas that are closer to the equator than to the poles. Polar stratospheric clouds have a great impact on radiative forcing. Atmospheric Window. A continues record of annual average atmospheric CO2 concentrations from Mauna Loa, Hawaii Revels. Polar stratospheric clouds (PSCs), also known as nacreous clouds from nacre, or mother of pearl, due to their iridescence, are clouds in the winter polar stratosphere. The … STUDY. At even lower temperatures(188 K … UV-B. We show that the ozone hole develops and the clouds dissipate in the same place and at the same time. Learn. Any ice growth was slowed immensely and would lead to any present ice melting. tinachmielewski. An area in the stratosphere where ozone is highly concentrated. Polar stratospheric clouds easily top the aurora borealis when it comes to sheer “wow” factor, but there’s just one problem with their staggering beauty: they’re a sign of something bad. (2) They can monitor hurricane movement. This pho - tograph of an Arctic polar stratospheric cloud (PSC) was taken from the ground at Kiruna, Sweden (67°N), on 27 January 2000. When temperatures fall below about -80 degrees, high-altitude clouds made of water and nitric acid begin to form. Air motions move ozone depleting substances to the atmosphere. Antarctica has 5-6 months of these temperatures. PSCs were sighted between 10 and 25 km and were usually first observed by mid‐June. what does ozone shield us from. 17:49. Create. Polar-Stratospheric Clouds. Polar stratospheric clouds (PSCs) play a central role in the formation of the ozone hole in the Antarctic and Arctic. 32.
