Ted Shepherd, outgoing co-Chair of the SPARC SSG, gave an overview of the SPARC (Stratospheric Processes And their Role in Climate) core project. He described the ‘modus operandi’ of SPARC, which involves identifying ‘bite-sized’ activities with clear deliverables, and managing all SPARC activities collectively at the SSG level. This sort of management model, which enables flexibility and helps the integration and communication between activities, may be appropriate for CliC. He also outlined several scientific points of contact between SPARC and CliC: the impact of stratospheric ozone depletion and recovery on Antarctic surface climate, Southern Ocean circulation, and sea-ice extent; the impact of stratospheric sudden warmings on NH high-latitude wintertime climate; and the role of the stratosphere in modulating the Arctic surface pressure response to climate change.

Presented by Ted Shepherd, University of Reading, at the 9th CliC Scientific Steering Group meeting in Potsdam, Germany 2013.

The atmosphere-ocean boundary layer in which sea ice resides includes many complex processes that require a more realistic treatment in GCMs, particularly as models move toward full earth system descriptions. The primary purpose of the workshop was to define and discuss such coupled processes...
