WXlog/20050625 Hail
From CSU-CHILL
The presence of quasi-spherical / tumbling hailstones caused near 0 dB Zdr values to appear in the center of a large thunderstorm located approximately 45 km southeast of CHILL (see cursor). The surrounding precipitation was primarily composed of large, oblate raindrops. This resulted in a ring of positive Zdr's surrounding the low Zdr "hail hole". The reduced correlation levels in the hail region indicated that the hail was mixed with rain.
