A51S:
Stratosphere–Troposphere Coupling: Large-Scale Atmospheric Dynamics and Transport I Posters


Submit an Abstract to this Session


Session ID#: 51534

Session Description:
Numerous studies have shown that stratospheric variability impacts surface weather and climate on timescales ranging from days to decades. In addition, the stratosphere affects tropospheric composition not only through the stratosphere-to-troposphere transport of ozone but also by modulating tropospheric dynamics. This session will cover all aspects of stratospheric dynamics and transport, as well as the two-way coupling between the stratosphere and the troposphere. Examples includes dynamical coupling during stratospheric sudden warming events and stratospheric modulation of the midlatitude jet streams and associated impacts on pollution transport. Studies focusing on tropical interactions are also welcome. Abstracts involving theoretical, modeling, and observational studies of the dynamics, transport, variability, and trends in the stratosphere are encouraged, as well as those investigating the stratosphere's role in setting surface climate and composition in the past, present, and future.
