Vertical transport of water, aerosol, and trace gases in extratropical cyclones and in particular the warm-conveyor belt (WCB) play an important role for the UTLS composition. How large this contribution is, how well it is represented in high-resolution models, and what therefore our predictive capability for future changes in the vertical transport is, will be ad-dressed in this project. We will employ large perturbed parameter ensembles in combination with the observational data obtained by other projects in the CRC to find constraints on the model representation of WCB moisture transport. In addi-tion, novel large ensembles will be developed that allow to explore the climatological WCB moisture transport in different climate states.

水、气溶胶和痕量气体在对流层外气旋，特别是暖输送带（WCB）中的垂直输送对UTLS的组成起着重要作用。这一贡献有多大，它在高分辨率模型中的表现如何，以及我们对垂直输送未来变化的预测能力如何，将在本项目中得到解决。我们将采用大扰动参数合奏与CRC中的其他项目获得的观测数据相结合，找到WCB水分输送的模型表示的限制。此外，将开发新的大型集合，以探索不同气候状态下的气候学WCB水分输送。
