Munich Physics Colloquium: "The response of the global stratospheric circulation to climate change"

Monday, 23 April, 2018

Prof. Dr. Hella Garny

(Meteorologisches Institut, LMU)

The role of the stratosphere in the climate system is increasingly being appreciated, and it is known that the circulation of the stratosphere can significantly influence surface climate and weather. The fate of the large-scale circulation of the stratosphere in a changing climate has become a much discussed topic. Despite some progress observational evidence on circulation changes is still not reconciled with model simulations and with our mechanistic understanding. The key open questions on large-scale circulation changes and their possible impacts on the climate systemare:

  1. 1. Process understanding: How is observable tracer transport coupled to the wave-driven mean mass circulation, the residual circulation?
  2. 2. How large is the uncertainty in the projections due to sub-grid scale parametrized wave forcing of the circulation?
  3. 3. How certain is the deduction of observational measures of stratospheric transport times?
