Zdr depression. Zdr depression.

The appearance of the positive Zdr values associated with oblate raindrops does not occur until lower heights are reached in a precipitation shaft at 15 km range. This Zdr depression is a consequence of the longer time (and greater fall distance) necessary to fully melt more massive ice particles.
