Fig. 4From: Toward reduction of the uncertainties in climate sensitivity due to cloud processes using a global non-hydrostatic atmospheric modelRelationships between horizontally averaged radar reflectivity Zm and optical depth from cloud top, τd, for cloud condensation nuclei with weak updraft. a–d Continental cloud condensation nuclei. e–h Maritime cloud condensation nuclei. Arrays A, B, and C indicate the first, second, and third path, respectively (refer to the text). The diagram in the upper left shows the slope factor defined in Suzuki et al. (2010).
