[1]本文研究了气候变化中环流变化对平流层和对流层臭氧交换的影响。我们已经确定，在未来的气候中，臭氧净输送到对流层的增加了37%，尽管臭氧寿命的减少意味着对流层的总体负担减少。在中纬度到高纬度地区，预计春季地面臭氧会增加。然而，这些增长并不显著。据预测，对流层上部区域的臭氧将显著增加。在气候变化情景中，平流层对对流层臭氧的贡献（O（3）s示踪剂）普遍增加，这表明平流层在未来将发挥更重要的作用。
[1] This paper investigates the impact of circulation changes in a changed climate on the exchange of ozone between the stratosphere and the troposphere. We have identified an increase in the net transport of ozone into the troposphere in the future climate of 37%, although a decreased ozone lifetime means that the overall tropospheric burden decreases. There are regions in the midlatitudes to high latitudes where surface ozone is predicted to increase in the spring. However, these increases are not significant. Significant ozone increases are predicted in regions of the upper troposphere. The general increase in the stratospheric contribution (O(3)s tracer) to tropospheric ozone in the climate changed scenario indicates that the stratosphere will play an even more significant role in the future.
