M12 - Middle Atmosphere Symposium (ICMA)

Convenor: Elisa Manzini
Co-Convenors: Bernd Funke, Michaela Hegglin, Christoph Jacobi, Irina A. Mironova, Eugene Rozanov 

The middle atmosphere extends from the tropopause to the lower hermosphere and is of particular interest to Earth system science due to its relevance to life on Earth and climate. Main features of the middle atmosphere include the ozone layer, which protects the Earth’s surface from harmful UV-radiation, and stratospheric dynamical phenomena, such as the polar vortex and the Quasi-Biennial Oscillation, which together with smaller scale gravity waves, are crucial to the circulation, weather teleconnection patterns, and global climate. The Symposium covers all aspects of middle atmospheric science, with emphasis on the interaction between dynamics, radiation and chemistry within the middle atmosphere itself and between the middle atmosphere and the troposphere. This is the core symposium of ICMA (International Commission on the Middle atmosphere).

Observational, modeling, theoretical, and laboratory studies are all solicited. Research topics include (but are not limited to):

  • Gravity waves: their generation, propagation and breaking
  • Intraseasonal, interannual and longer timescale dynamical variability
  • Middle atmosphere response to anthropogenic and natural forcings
  • Stratospheric/mesospheric chemistry and ozone
  • Radiation, microphysics, chemistry and dynamics at the tropopause
  • Transport and mixing in multiple spatial scales
  • Tropical / extratropical dynamical interactions
  • Mechanisms of stratosphere-troposphere coupling, at all time scales
