Research Area B: Small scale dynamics and microphysics
Research Questions (B)
RQ-B1: What is the impact of small-scale microphysical processes on the structure of the tropopause region and
what are the implications for cross tropopause exchange?
RQ-B2: How do gravity waves, instabilities and turbulence in the UTLS affect troposphere-stratosphere coupling,
mixing and cloud life cycles at the tropopause and how does the UTLS affect the waves’ propagation?
RQ-B3: What is the effect of diabatic dynamics on the UTLS composition and cross tropopause exchange from
the turbulent to the synoptic scale?
