However, even slight changes in the meteorology of the region this month could affect the rate of depletion of ozone and how large an area the ozone hole might span.
即使这一地区在本月之内出现任何的天气变化都有可能影响臭氧含量的变动，并决定臭氧空洞将扩大多少。
Taken together, the two observed that circulation changes accounted for "virtually all" of the year-to-year changes in springtime Antarctic ozone, Salby and colleagues write.
综上，环流变化解释了春季发生在南极臭氧层的所有年际变化，Salby及其同事们写道。
Subtracting their estimate of the natural changes in ozone from actual changes, the group finds “a clear upward trend since the late 1990s” in the hole's ozone that represents “a systematic rebound.”
从臭氧层的实际变化中除去正常情况下臭氧层的变化（对照），这个研究团队发现“自20世纪90年代以来臭氧层空洞缩小趋势”有一个系统性的机制。
But no one had been able to take those circulation changes into account accurately enough to reveal the underlying ozone recovery.
但是很少有人可以准确无误地计算出环流中的这些变化，因而很难揭示出臭氧层恢复的趋势。
The pollution had destroyed ozone layer and caused many changes in weather.
污染破坏了臭氧层，并引起了许多天气变化。
These crystals may help begin the chemical changes that result in the destruction of ozone.
这些晶体可以有助于触发导致臭氧受到破坏的化学变化。
Increasing greenhouse gases and likely ozone recovery will be the two most important factors influencing changes in stratospheric temperatures in the 21st century.
温室气体增加和可能的臭氧恢复将是影响21世纪平流层温度变化的两个主要因素。
One of the most disturbing aspects of the changes in Earth is the rate at which chemical pollutants produced by human activity are destroying the protective layer of ozone in Earth's upper atmosphere.
地球上的变化最令人烦扰的方面之一，是人类活动所产生的化学污染正在迅速破坏地球上部大气圈臭氧保护层。
The calculation results show that the ultraviolet radiation received at the ground is more sensitive to changes in atmospheric turbidity than changes in the total ozone amount.
最后给出了北京地区地面太阳紫外总辐射的变化趋势，计算结果表明，地面太阳紫外总辐射对大气浑浊度的变化比对大气臭氧总量的变化敏感得多。
Decadal changes in EESC are similar to those of the ozone hole, and interannual variations of ozone are closely related with stratospheric temperature.
EESC的年代际变化与臭氧变化趋势相似，臭氧的年际变化与平流层温度关系密切。
The thin ozone layer has proved to be an Achilles heel that may be seriously injured by apparently moderate changes in the composition of the atmosphere.
薄臭氧层已被证明是一个通过大气明显中等变化，会被严重伤害的要害。
The ozone low varies with the season, and changes strongest in winter and weakest in summer.
该臭氧亏损有明显的季节变化：冬季最强，夏季最弱。
