Multiple tropopauses are structures that regularly recur in the midlatitudes. Recent studies have relied on the notion of the excursion of tropical air from the upper troposphere into higher latitudes, thereby overlaying the tropopause of the midlatitudes. We herein analyse the origin and characteristics of the air at the Boulder radiosonde station, between the first and second tropopauses combining an analysis of radiosonde data with a Lagrangian approach based on the FlexPart model and ERA-40 analysis data. Our results show that the air between both tropopauses has its origin in midlatitudes.
多个对流层顶是在中纬度地区经常出现的结构。最近的研究依赖于热带气团从对流层上部向高纬度地区移动的概念,从而覆盖了中纬度地区的对流层顶。在此,我们结合探空仪数据分析与基于FlexPart模型和ERA - 40分析数据的拉格朗日方法,分析了博尔德探空站在第一和第二对流层顶之间空气的来源和特征。我们的结果表明,两个对流层顶之间的空气起源于中纬度地区。
