Z - Zdr anti-correlation in an RHI scan through an ice cloud Differential reflectivity (Zdr) values are most positive in the outer, low-reflectivity regions of an echo layer where the scatterers are mainly horizontally-oriented planar ice crystals. In the higher reflectivity regions enclosed by the yellow 14 dBZ contour, the presence of quasi-spherical clumps of aggregated ice crystals lowers the Zdr to ~0 dB. Photo credit: Patrick Kennedy |
