The bane of the air pollution

  Air pollution to the influence of the weather very big, the pollutant that air pollution exhaust play chess a region and global weathers and will produce the certain influence, particularly to world weather of influence, see from the farsighted standpoint, this kind of the influence will be very serious.

One:The content increment of the carbon dioxide in the atmosphere:

  It imply various complicated composition in the fuel, at burnable after produce various harmful material, even not the fuel with miscellaneous quality attains the complete combustion, also wanting to produce the water and carbon dioxides, positive because the fuel combustion makes the carbon dioxide in the atmosphere density increased continuously, breaking the balance of the nature carbon dioxide, to go to and may cause" green house effect", cause the Earth air temperature rise.
Two: the ozone layer break

   The ozone layer is the best protection of the Earth umbrella, it absorbs to come from big and parts of ultraviolet ray of the sun.However be close to 20 years of science research and atmosphereses to prognosticate to discover:Annually spring South Pole ozone layer within atmosphere always at become thin, in fact exist an ozone" hole" in very atmospher 
   This kind of ozone exhaust the phenomenon is a kind of abnormal phenomenon, whether this expresses that this ultraviolet ray absorbs the layer or not is being placed in the global disaster?Pass the continuous science research, the people discover the serious breakage of material that social activity of mankind release ozone layer, certainly this kind of phenomenon still is affect by special weather appearance( the pole 涡 , cold of even flow the layer temperature, very even flow the layer cloud) in this region.

大气污染的危害

大气污染对气候的影响很大,大气污染排放的污染物对局部地区和全球气候都会产生一定影响,尤其对全球气候的影响,从长远的观点看,这种影响将是很严重的。

一:大气中二氧化碳的含量增加:

燃料中含有各种复杂的成分,在燃烧后产生各种有害物质,即使不含杂质的燃料达到完全燃烧,也要产生水和二氧化碳,正因为燃料燃烧使大气中的二氧化碳浓度不断增加,破坏了自然界二氧化碳的平衡,以至可能引发“温室效应”,致使地球气温上升。

二:臭氧层破坏

臭氧层是地球最好的保护伞,它吸收了来自太阳的大部分紫外线。然而近二十年的科学研究和大气观测发现:每年春季南极大气中的臭氧层一直在变薄,事实上在极地大气中存在一个臭氧“洞”

这种臭氧损耗现象是一种反常现象,这是否表明这一紫外线吸收层正处于全球性灾难呢?通过不断的科学研究,人们发现人类社会活动释放的物质严重的破坏了臭氧层,当然这种现象还受到这一地区独特的气象状态(极涡、寒冷的平流层温度、极地平流层云)的影响。
