Summary

An acceptable theory on hail formation should be based on the general physical conditions prevailing within thunderstorm clouds and in particular on the processes of nucleation and growth of ice particles. An attempt has been made to approach this problem from the experimental side by means of a vertical wind tunnel offering a wide range of airconditions. In this paper the Swiss Hail Tunnel as it has been built in the Laboratories of the Federal Snow and Avalanche Research Institute, Weissfluhjoch, Davos is described and discussed. It is shown that in the tunnel stationary and variable conditions can be reproduced similar to those to be expected in a natural hail-producing atmosphere.
