Stratosphere-troposphere Exchange
In the past, studies of stratosphere-troposphere exchange of mass and chemical species have mainly emphasized the synopticand small-scale mechanisms of exchange. This review, however, includes also the global-scale aspects of exchange, such as the transport across an isentropic surface (potential temperature about 380 K) that in the tropics lies just above the tropopause, near the 100-hPa press...
متن کاملDirect Diagnoses of Stratosphere–Troposphere Exchange
This study discusses the direct diagnosis of stratosphere–troposphere exchange. The method introduced by Wei is applied to the Goddard Earth Observation System assimilated dataset. In many respects, the results generally agree with those of other studies using the same method and different datasets. However, sensitivity tests and theoretical considerations indicate that the instantaneous two-wa...
متن کاملStratosphere-troposphere exchange: a case study
Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract An important part of extra-tropical stratosphere-to-troposphere transport occurs in association with baroclinic wave breaking and cutoff decay at the tropopause. In the last decade many studies have attempted to estimate stratosphere-troposphere exchange ...
متن کاملCO2 in the upper troposphere: Influence of stratosphere-troposphere exchange
[1] A two-dimensional transport model constrained to measured surface CO2 concentrations was used to simulate the spatial and temporal variation of CO2 in the atmosphere for the period from 1975 to 2004. We find that the amplitude, phase and shape of the CO2 seasonal cycle vary as a function of both altitude and latitude. Cross tropopause exchanges, especially the downward branch of the Brewer-...
متن کاملSources of plutonium in the atmosphere and stratosphere-troposphere mixing
Plutonium isotopes have primarily been injected to the stratosphere by the atmospheric nuclear weapon tests and the burn-up of the SNAP-9A satellite. Here we show by using published data that the stratospheric plutonium exponentially decreased with apparent residence time of 1.5 ± 0.5 years, and that the temporal variations of plutonium in surface air followed the stratospheric trends until the...
