Orbe, C., D.W. Waugh, and P.A. Newman, 2015: Air-mass origin in the tropical lower stratosphere: The influence of Asian boundary layer air. Geophys. Res. Lett., 42, no. 10, 4240-4248, doi:10.1002/2015GL063937.

A climatology of air-mass origin in the tropical lower stratosphere is presented for the Goddard Earth Observing System Chemistry Climate Model. During late boreal summer and fall, air-mass fractions reveal that as much as 20% of the air in the tropical lower stratosphere last contacted the planetary boundary layer (PBL) over Asia; by comparison, the air-mass fractions corresponding to last PBL contact over North America and over Europe are negligible. Asian air reaches the extratropical tropopause within a few days of leaving the boundary layer and is quasi-horizontally transported into the tropical lower stratosphere, where it persists until January. The rapid injection of Asian air into the lower stratosphere — and its persistence in the deep tropics through late (boreal) winter — is important as industrial emissions over East Asia continue to increase. Hence, the Asian monsoon may play an increasingly important role in shaping stratospheric composition.
