摘要
利用ＴＯＭＳ资料分析了南北极区大气臭氧总量的多年（１９７９～１９９２）趋势变化、年际变化、季节变化及周期性变化特征。结果表明，近十余年来南北极区大气臭氧总量都是下降的，并且存在转折现象，但两者具有不同的多年变化特征和地理分布特征；南北极区的臭氧减少都是春季下降最快；南北极区存在不同的周期振荡现象，南极地区比北极地区表现出更强的周期振荡特征。最后探讨了全球大气臭氧变化与大气温度场的关系，表明前者对后者具有重要影响。
In the context of the TOMS data,investigated are atmospherical total ozone secular trends (1979～1992),interannual changes as well as seasonal and periodic variations over Arctic and Antarctic. Results indicate that total ozone decreases persistently and has a turning point during its decline over northern and southern polar regions in recent decades.However,total ozone over the two polar regions has different secular trends and geographical distributions.The ozone declines most rapidly during spring over both polar regions,but fluctuates in different periods with stronger oscillation over Antarctic than over Arctic.In addition, the relation between atmospheric ozone variation and temperature is discussed,indicating that the former has important influence on the latter.
