The thermodynamic and kinematic structure of two stable orographic storms were described in Part I based on instrumented aircraft data and single Doppler radar data. The precipitation processes in these storms are described in this paper. The depletion rates by deposition were less than half the condensation supply rates, and the liquid water contents remained very low.
Accretion is deduced to be the dominant process, which acts to deplete the condensate to near zero.
Deep, stable orographic storms over the Sierra barrier, therefore, develop an efficient glaciation process.
