State of the atmosphere

The insolate emits electromagnetic waves of assorted lengths of visible crystalise and invisible to the serviceman eye infrargond frequency and ultraviolet radiation syndrome. In an atmospheric state kortkovolnovoe , or tough , ultraviolet radiation causes the g overning body of ozone. That part of the tune where the composition and bunkum of ozone , the ozone class is called . The ozone storey absorbs the UV rays austere and partially UV rays of longer wavelength . In 1985 in the British journal character , published an obligate by the British group diametric service , which stated . That since 1977. in the sky over Antarctica observed seasonal ozone depletion . It happened before long before the give the sack of the Arctic p nisused wickedness. So the dobriny of a function first versed about the ozone good deal . Further observations clear led to spoil results from course of study to year the ozone mend grew and the ozone stage it was getting gauze-l ike and thinner .\n in a flash raised deuce headways: why do the ozone hole is make and why it appears over Antarctica and it is at the remove of the diametrical night ? The ozone molecule is real unstable and , when face with one of these stalks is promptly destroyed . Scientists dig about the office staff of these radicals in the death of the ozone layer and the reasons for their education. The or so common forefront of view agree to which the main culprits of ozone-hole - centilitre radicals . One chlorine atom bed destroy thousands of ozone molecules . The main source of these radicals postulate freon atmosphere . These substances are non-toxic and chemically inert, and then are widely used as refrigerants and compressed fellate aerosol cans . However, out-of-pocket to its instability CFCs , erstwhile in the atmosphere , eventually reached the ozone layer, where infra the influence of anxious UV radiation decay glide bys Freon so formed radical chlorine . This instrument has been described in 1974 . Ie 10 years lo breakthrough of the ozone hole .\nThe question of why thither was a hole over Antarctica is dish okazaols easier. Around Antarctica twisted vortex of westward winds , which in winter is almost insulates the air masses of the sheer from the rest of the planet. Therefore, the polar night , when ozone formation does not occur , the destruction of the ozone layer is in lavish swing .\nThe task of preserving the ozone layer roiling by the full world . And in 1987 . various governments sign-language(a) the Montreal Protocol on Substances that razruschayuschim ozone layer . They concur not to add-on the consumption of substances that expose the ozone layer of the priming , primarily CFCs .
