论文摘要
2015/2016年冬季，西伯利亚在冬季使用Airs和Caliop卫星数据进行了深臭氧小孔（OMH）形成的特征和机制。臭氧总圆柱的耗竭主要是由于下层平流层中臭氧混合比的强烈降低，在70 hpa的压力水平接近50％。 OMH的形成与动态因子密切相关，包括对流层顶的高度增加和对流层的臭氧底部亚热带空气的对流，这与大气阻塞有关。同样，OMH形成的重要因素是由于臭氧从OMH区域的流出增加，平流层臭氧减少。评估了高层平流层云表面上含卤素化合物对OMH形成的催化反应引起的平流层臭氧化学破坏的贡献。
The characteristic features and mechanisms of the formation of a deep ozone mini-hole (OMH) in winter 2015/2016 over Siberia were carried out using AIRS and CALIOP satellite data. The depletion in the total column ozone was caused mainly by a strong decrease in ozone mixing ratio in the lower stratosphere, reaching 50% near the pressure level of 70 hPa. The formation of OMH was closely related to the dynamic factors including an increase in the tropopause height and advection in the troposphere of ozone-depleted subtropical air, which were associated with atmospheric blocking. Also, an important factor of OMH formation was ozone decrease in the stratosphere due to increased outflow of ozone from the area of the OMH. The contribution of chemical destruction of stratospheric ozone, due to catalytic reactions with halogen-containing compounds on the surface of polar stratospheric clouds to the OMH formation, was evaluated.
