The representation of sub-grid scale processes such as mixing and cloud formation is a common and highly problematic feature of tropospheric models and is recognized to have important effects on the large scale. In contrast, the effects of sub-grid scale processes have largely been ignored in stratospheric chemical and microphysical models, hence assessments of their effect on predictions of stratospheric models remain highly uncertain. However, several sub-grid processes have potentially have implications for large scale stratospheric composition, such as gravity wave-induced polar stratospheric cloud formation, small-scale structure in inconcentration fields due to incomplete mixing, and sub-grid scale processes occurring at the tropopause. The Mesoscale Processes in the Stratosphere workshop was organized to assess the extent to which these sub-grid scale processes affect the chemical and microphysical state of the stratosphere.
