Summary

The first two years of the Swiss randomized antihail project does not yet allow any statement having statistical weight about the effect of the AgI seedings to prevent hail, neither in a positive, negative, nor indifferent sense. However, the precipitation patterns display indications for a strong increase of the rain as a result of the AgI seeding by ground generators. According to the general design the project will be carried through for the time of five years in the expectation to arrive until then to some definite decisions as to the effects of the silver iodide on hail formation.
