      abstract     = {Numerous studies have presented evidence that the Asian
                      summer monsoon anticyclone substantially influences the
                      distribution of trace gases – including water vapour –
                      in the upper troposphere and lower stratosphere (e.g. Santee
                      et al., 2017). Stratospheric water vapour in turn strongly
                      affects surface climate (see e.g. Solomon et al., 2010).
                      Here, we analyse the characteristics of water vapour
                      transport from the upper troposphere in the Asian monsoon
                      region to the stratosphere employing a multiannual
                      simulation with the chemistry-transport model CLaMS
                      (Chemical Lagrangian Model of the Stratosphere). This
                      simulation is driven by meteorological data from ERA-Interim
                      and features a water vapour tagging that allows us to assess
                      the contributions of different upper tropospheric source
                      regions to the stratospheric water vapour budget. Our
                      results complement the analysis of air mass transport
                      through the Asian monsoon anticyclone by Ploeger et al.
                      (2017). The results show that the transport characteristics
                      for water vapour are mainly determined by the bulk mass
                      transport from the Asian monsoon region. Further, we find
                      that, although the relative contribution from the Asian
                      monsoon region to water vapour in the deep tropics is rather
                      small (average peak contribution of $14 \%$ at 450 K),
                      the Asian monsoon region is very efficient in transporting
                      water vapour to this region (when judged according to its
                      comparatively small spatial extent). With respect to the
                      Northern Hemisphere extratropics, the Asian monsoon region
                      is much more impactful and efficient regarding water vapour
                      transport than e.g. the North American monsoon region
                      (averaged maximum contributions at 400 K of $29 \%$
                      versus $6.4 \%).$},
