  1. Profiling radar observations of coastal orographic feeder cloud structure during CALJET, PACJET and HMT-West David Kingsmill University of Colorado, CIRES and NOAA ESRL 36th Radar Conference, 18 September 2013 Bergeron 1965 Doppler Radar Aircraft

  2. CALJET, PACJET and HMT-West: Improve understanding and prediction of land-falling Pacific winter storms SPROF data at CZC NOAA ESRL S-band precipitation profiler (SPROF) at Cazadero (CZC)

  11. Summary

  12. Summary Episode 2 had larger cross-barrier bulk IWV flux and precipitation rates compared to Episode 1 The AR rode up and over the SBJ during both episodes, but there were structural differences: Episode 1 SBJ southeasterly at ~25-30 m/s, ~0.2-1.5 km MSL SBJ-AR interface extended to west edge of Central Valley and sloped SW-NE at 1-2 % Episode 2 SBJ southerly at ~20-25 m/s, ~0.3-2.5 km MSL SBJ-AR interface extended to west half of Central Valley and sloped SW-NE at 2-4 %
