Cloud-seeding experiments are hard to evaluate because of difficulty in segregating artificially created effects of seeding from natural processes. Control areas in the immediate vicinity which, from previously established records, are not liable to produce abnormal precipitation, should be chosen. It becomes increasingly difficult to find a control area which is not influenced by another cloud-seeding operation conducted nearby.
