Abstract: Replicas of a hailstone that weighed 766 gm and which had large spikes confined mainly to one side were dropped from heights of up to 900 m and also tested in a wind tunnel to determine the hailstone's aerodynamic properties. ...

Abstract: The reflecting properties of microscopic corrugations on the surface of cold-rolled aluminum sheet used in hailpads led to a new technique for determining the size of hailstones. Hailstone models of various shapes and sizes ...
