[A-AS08] Stratosphere-troposphere interaction

convener:Takatoshi Sakazaki(Graduate School of Science, Kyoto University), Takenari Kinoshita(Japan Agency for Marine-Earth Science and Technology), Pu Lin(Princeton University/NOAA Geophysical Fluid Dynamics Laboratory), Peter Hitchcock(Cornell University)

The dynamical, radiative, and chemical processes involved in the interactions between the stratosphere and troposphere are essential for understanding the present and future climate. Both observed data and high-resolution models have now clearly demonstrated that stratospheric processes can affect various tropospheric phenomena. Recently, processes coupling the troposphere and stratosphere in the tropical region have become a new focus.
It has also been shown that the accuracy of tropospheric sub-seasonal and seasonal scale forecasts can be improved by more accurate representations of the stratosphere. As a result, interest is increasing in the predictability and reproducibility of specific stratospheric phenomena, including the Quasi-Biennial Oscillation (QBO) and its recent disruption as well as Stratospheric Sudden Warmings (SSW).
This session will highlight recent progress in our understanding of stratosphere-troposphere interaction. We welcome studies of these and related phenomena in the troposphere and stratosphere (and mesosphere) based on observation, models and theory. Further, this session builds upon the middle atmosphere session traditionally held at the JpGU annual meetings and aims to provide a platform for sharing recent findings and promoting international collaborations on this topic.
