abstract = {Using the Chemical Langrangian Model of the Stratosphere
(CLaMS), which was developed in the last two decades, we
discuss the following, process-oriented questions: (i) how
to understand the formation of the extratropical mixing
layer, which separates the troposphere from the
stratosphere. (ii) what is the impact of mixing processes on
the tropopause inversion layer (TIL) and, finally, (iii) how
to explain the large annual cycle of ozone above the
tropical tropopause. Furthermore, CLaMS is also applie to
understand the atmosperic long-term variability. Here, we
discuss how major sudden stratospheric warmings influence
stratospheric water vapor trends and how tropospheric ozone
trends can be separated from the stratospheric influence.
Finally, we quantify the influence of uncertainties in the
understanding of atmospheric mixing on the uncertainties in
radiative forcing. The opportunity to avoid, or at least to
minimize, the numerical diffusion ever present in Eulerian
numerical schemes is the strongest motivation for the
Langrangian formulation of transport. We show how
Langrangian transport implemented in CLaMS goes even further
and uses the numerical diffusion to parameterize physical
mixing. This $\textit{kumulative Habilitationsschrift}$ is
based on 16 studies, which are appended to the text (along
with a brief description of the highlights in chapters 1 and
3), that were undertaken with the aim of improving our
knowledge of various transport processes in the stratosphere
and upper troposphere.},
