Prior to a cloud-to-ground lightning discharge nearby, the radar echo overhead was usually quite weak, indicating low intensities of precipitation there. Following the lightning it was observed sometimes that in the region of the cloud where the discharge occurred the radar echo intensity rapidly increased, and shortly thereafter a gush of rain or hail fell nearby.These studies confirm earlier radar observations, made by the authors at Grand Bahama Island, B.W.I., in which it was found that lightning is often followed in the cloud by a rapidly intensifying echo and then by a gush of rain at the ground.

The modification was accomplished by the release of negative space charges into the air from elevated wires connected to a high-voltage power supply. Anomalous distributions of charge were observed in some clouds with low bases that grew over the charge source. Abnormal Polarity of Thunderclouds Grown from Negatively Charged Air.

The normal, positive space charge in the sub-cloud air was reversed by negative charge released from an electrified wire, suspended across a 2-kilometer-wide canyon.

SAO/NASA ADS Physics Abstract Service · Reads History· · Translate This Page Abstract Observational data and theoretical considerations in the literature suggest that the electrical activity of large thunderstorms can result in lightning and other dielectric breakdown processes within the stratosphere.
Field investigations have been undertaken to secure data on the nature of these discharges and their frequency of occurrence. Studies of lightning spectra made from the ground in New York and New Mexico failed to indicate anomalous spectra that might characterize low pressure discharges in the stratosphere. Tropospheric electrification. SAO/NASA ADS Physics Abstract Service · Reads History· · Translate This Page Abstract The solid Earth carried a negative charge of approximately 10 C to the 6 th power and the lower atmosphere an equal, opposite charge.
While a number of charging processes in the lower atmosphere are involved, such as erupting volcanoes, snow, sand and dust storms, and the bubbles bursting from the oceans, the primary cause of the Earth's electrification is activity of thunderstorms.

SAO/NASA ADS Physics Abstract Service · Electronic On-line Article (HTML)· Reads History· · Translate This Page Abstract In Peter Hobbs' “Clouds: Their Beauty and Challenge,” (Eos, March 29, 1994) a few points are deserving of comment.He is indeed correct that “The cloud seeding hypothesis was based on a very simple, naive picture of the factors that control precipitation in real clouds.”
It is worth noting that at the time almost the entire meteorological community shared the naive view that all precipitation particles begin as ice crystals according to the theory of Tor Bergeron. There can be little doubt that 4 decades hence some of the most cherished ideas of today will also appear to be naive. The Atmospheric Electricity Paradigm.

A satisfactory understanding of how a thunderstorm works will require a continuing series of investigations to explore the complicated interrelationships among these phenomena. Until now the major effort has been devoted to studies of how precipitation causes electrification.For a century, investigations of thunderstorms have been dominated by the idea that lightning is produced by a charge-separation process within the cloud caused by failing precipitation.
