A case study is presented to illustrate the small and medium scale air motion and precipitation patterns within a travelling wave depression. Air motion has been studied by means of isentropic and Doppler radar analyses; precipitation patterns have been studied by means of meso‐analysis of autographic rate‐of‐rainfall records and conventional 3‐dimensional radar data. The results confirm and elaborate upon earlier studies in which precipitation generation is classified according to whether it is due to large‐scale ascent alone or is modified by vertical instability. The influence of orography is also discussed.
