Lagrangian analysis of the role of extratropical cyclones for UTLS aerosol and humidity (B08)

水、气溶胶和微量气体在温带气旋中的垂直输送，特别是暖传送带(WCB)对UTLS的组成起着重要的作用。这一贡献有多大，它在高分辨率模式中的表现如何，以及我们对垂直交通未来变化的预测能力如何，将在这个项目中得到强调。我们将使用大扰动参数集合，结合华润中心其他项目获得的观测数据，寻找对WCB水汽输送模式表示的限制。此外，还将开发新的大型系综，以探索不同气候状态下气候学WCB的水汽输送。

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.
