Observations at Cazadero, CA (CZD) on 21–22 March 2005 (from Coplen et al., 2008). Time increases from right to left. (a) Time–height section of equivalent radar reflectivity factor (dBZe; see colour scale). (b) Contoured drop-size distributions of rainfall at the surface as a function of time and diameter (see colour scale). Open squares indicate objective categorisation of the rainfall occurring during selected half-hour periods; BB (red), rain with a radar brightband signature; NBB (blue), rain without a radar brightband signature; Conv. (yellow), convection rain. (c) Histogram of hourly rainfall (mm). (d) Time series of stable hydrogen isotopic composition of 30-min, time-integrated precipitation samples. A primary change in precipitation microphysical properties is marked by the vertical dashed lines in Fig. 2b–d. Zones of distinct isotope behaviour are enclosed by the vertical lines and labelled with Roman numerals in (d): I, pre-cold frontal precipitation of marine air; II, transitional mixing of I and III; III, precipitation from deep, cold cloud layer via the seeder–feeder mechanism; IV, transitional mixing between III and V; V, shallow, locally generated orographic rain; VI, light rainfall with passage of cold front.

HR, pink panel, higher rainout, decreasing or low δ 2HVSMOW values. LR, blue panel, lower rainout, increasing or high δ 2HVSMOW values. During a 3-hour period (21 UTC 23 February 2010 to 0 UTC 24 February 2010) wind-profiling data were not acquired. Time increases from right to left.
