Melting level variations in a thunderstorm. Melting level variations in a thunderstorm.

Zdr values become more positive as melting ice hydrometeors develop an increasing liquid water component. The small ice particles in a weak shower near 7 km range go through the melting process in a narrow layer near 2 km AGL. The bigger ice particles within the 40 dBZ contour descend to near surface heights before melting effects appear.
