简介：从臭氧卫星观察和一般循环的数据分析，这篇文章讨论季节并且在西藏上的全部的臭氧的interannual变化。分析在西藏上在interannual臭氧变化在伪鈥擝iennial摆动(QBO)上被做了，与在热带上并且非的QBO比较在西藏的一样的纬度的鈥攎ountain区域。事实被看那西藏臭氧QBO有29个月的一个平均时期，与8杜的一个平均振幅。西藏臭氧QBO是到在热带上的同温层的风QBO的反相，即30hPa鈥攚ind是的热带在东方，臭氧有剩余，和副诗句。这篇文章也在西藏上在臭氧QBO上讨论大气的转移的影响。关键词臭氧-QBO-西藏作者被强迫到中国科学院(KZ951-A-205-05)，中国(49775276)的国家自然科学基础和大气的物理的研究所，中国科学院(8-2212)。作者希望谢谢在NASA/戈达德空间飞行中心处理队的臭氧，美国为他们TOMS臭氧7的客气的预备，NRCC，加拿大，为他们的10.7厘米太阳的收音机流动数据和NCAR为标准化了30hPa在新加坡的带的风数据。

简介：我们调查了内部冬季的年度变化在这篇论文的同温层的极的旋涡。文件结束分析证明可变性的二个模式统治同温层的极的旋涡在上内部年度时间规模。领先的模式(EOF1)反映极的旋涡的紧张变化并且被在极的区域之间的一块geopotential高度跷跷板描绘并且中间纬度。在极的旋涡的带的不对称的部分的第二个(EOF2)展览变化，它主要描述静止行星的波浪活动。作为最强壮内部在空气的年度变化信号，QBO被显示了主要影响极的旋涡的力量。在另一方面，ENSO周期最强壮内部在海洋的年度变化信号，被显示了主要在平流层与静止行星的波浪活动的变化被联系。球的循环也是的对流上的同温层的极的旋涡的可能的影响在这讨论了纸。
