| Session Description | This session is interested in the stratosphere-troposphere dynamical coupling and its predictability. The first focus is the general aspect of the dynamical coupling between stratosphere and troposphere and their mechanisms. The two-way interactions associated with polar vortex variability and quasi-biennial oscillation in both past and future climates are of particular interest. Their implications to short-term weather, longer-term climate variability, and future climate change are also welcome. The second focus is the SPARC activity SNAP (Stratospheric Network for the Assessment of Predictability) that aims to better understand stratospheric predictability. We invite abstracts that focus on the role of the stratosphere for the predictability of tropospheric forecast in medium-range to sub-seasonal time scale. This includes all aspects of the connections between stratospheric conditions and tropospheric weather: the predictability of weak vortex conditions such as stratospheric major and minor warmings, stratospheric final warmings and stratospheric vortex strengthening events. Advances in operational forecasting that enhance the predictability of stratospheric warming events and related skill in tropospheric forecasts are of particular interest. |
