Radar Detection of Cloud-Seeding Effects
Science, 1981The effects on precipitation of artificially seeding clouds with Dry Ice have been monitored from cloud to ground with a radar that has a wavelength of 8.6 millimeters.

Der Umstand, dass es selbst nach mehr als 10 Jahren nicht gelungen ist, die Wirkung einer Wolkenimpfung auf Regen- und Hagelfall sicher nachzuweisen, sowie Zweifel an der Bedeutung von Eisbildungskernen fur diese Phanomene lassen weitere konventionelle Impfversuche nicht als gerechtfertigt erscheinen, bis die Theorie der Niederschlagsprozesses ...

Santa Clara Valley, Calif., pioneered weather modification for increasing rainfall. After 15 years its program of cloud seeding is seen as an undoubted success, but one dependent on Santa Clara's unique geography and atmosphere.

Cloud Seeding and Cloud-to-Ground Lightning
Journal of Applied Meteorology, 1967Abstract During the summers of 1958 to 1962, convective clouds over a mountain range in southeastern Arizona were seeded by means of airborne silver-iodide generators. The data collected do not allow a conclusion that the seeding influenced the amount of cloud-to-ground lightning.

In partial response to Young, tests with advanced numerical models are suggested for evaluation of net effects of seeding on precipitation in seeded and adjacent areas. Shower seeding in the U.S. plains cannot produce significant precipitation unless there is stimulation of the flow process that forms clouds. Several papers on cloud seeding projects in

Planning cloud seeding research
Archiv für Meteorologie, Geophysik und Bioklimatologie Serie A, 1955It is suggested that a theory of cloud seeding needs to be developed before seeding experiments can be properly planned and assessed. This theory will arise from improved knowledge of cloud processes gained by the study of natural clouds. Some techniques used in observing shower clouds in Sweden are described, and some preliminary results mentioned.
