Radar Reflectivities of Hail Samples

Naturevolume 191pages266267 (1961) | Download Citation



IN the past few years quantitative measurements have been made of the radar reflectivity of many storms, particularly severe ones in which hail and even tornadoes have occurred. In particular, Donaldson has published and discussed vertical profiles of reflectivity of storms in the eastern United States1. He finds that the absolute magnitude of the reflectivity increases with the severity of the thunderstorm in the sequence rain, hail, large hail and tornadoes; and that in hail and tornado situations, the maximum reflectivity is found aloft at a height which increases with storm severity.
