摘　　要：使用2005—2015年夏季Aura卫星微波临边探测器(MLS)逐日臭氧观测资料,讨论了夏季青藏高原臭氧低值区的三维分布。研究发现,青藏高原臭氧不仅在对流层顶附近存在着臭氧低值区,而且在平流层上层(20~1 hPa)也存在显著的低值区。高原区上空50%以上的臭氧存在于21.5~1.2 hPa的范围内,因此平流层上层高原臭氧低值对高原臭氧谷来说也很重要。使用合成分析法对MLS夏季北半球昼夜臭氧进行研究,结果表明该低值区仅存在于白天。根据高原区平流层上层臭氧模拟数据的集合经验模态分解,得到IMF4的平均频率为0.09,平均周期为11.1年,正好对应太阳活动最强的周期。说明太阳辐射是影响高原平流层上层臭氧低值中心的一个因素。Using Aura satellite 10 years（ 2005—2015） summer（ from June to August） microwave limb sounder（ MLS） daily ozone observation data,the three-dimensional distribution of the core of ozone valley over the Qinghai-Tibetan Plateau in summer is analyzed. The results showthat the ozone valley in the Qinghai-Tibetan Plateau is not only in the tropopause,but also in the upper stratosphere（ 20 ~ 1 hPa）. More than 50% of the ozone over the plateau is in the range of 21. 5 ~ 1. 2 hPa,so for ozone valley upper stratospheric ozone plateau lowplateau is also very important. Then by using synthetic analysis method,MLS ozone in the Northern Hemisphere summer day and night were compared,and we can see there is a core of ozone valley on the plateau during the day. Next,by using Ensemble Empirical Mode Decomposition（ EEMD） to process total ozone analog data in the Plateau,the average frequency of IMF4 is 0. 09,that is to say the average period is 11. 1 years,exactly correspond to the strongest solar activity cycle. So solar activity is a factor for the core of ozone valley in the plateau upper stratosphere.
