This phenomenon is typically associated with a small difference between horizontally and vertically polarized reflectivities accompanying a high value for the horizontally polarized reflectivity. The presence of a bounded weak echo region in a radar signature indicates proper conditions for the formation of this phenomenon. Weak echoes from this phenomenon create a characteristic (*) three body scatter strike artifact in the radar signal. Graupel is sometimes called the “soft” form of this phenomenon (10[1])which is created when updrafts continuously lift this phenomenon until it grows large enough to fall to the ground. For 10 points, name this deadly form of icy precipitation which is characterized into classes like “quarter” and “golf ball” based on size. ■END■
