Quantification of water vapour transport from the Asian monsoon to the stratosphere

Abstract

We have performed multiannual simulations with the chemistry-transport model CLaMS (Chemical Lagrangian Model of the Stratosphere) to investigate water vapour transport from the Asian monsoon region to the stratosphere. We assess the transport pathways and efficiency of water vapour transport from the Asian monsoon region to the stratosphere and make comparisons with other source regions (e.g. the tropics). Our nalyses are related to the previously published work by Ploeger et al. (2017), who have analyzed mass transport from the Asian monsoon anticyclone to the stratosphere. The presented findings are related to the Final Meeting Sessions “Transport and dynamics” and “Global Implications” and have recently been published for discussion in Atmospheric Chemistry and Physics (Nützel et al., 2019).
