The North Dakota Thunderstorm Project: A Cooperative Study of High Plains Thunderstorms

Bulletin of the American Meteorological Society, 1992
Abstract The North Dakota Thunderstorm Project was conducted in the Bismarck, North Dakota, area from 12 June through 22 July 1989. The project deployed Doppler radars, cloud physics aircraft, and supporting instrumentation to study a variety of aspects of convective clouds. These included transport and dispersion; entrainment; cloud-ice initiation and

High energy electrons produced in a thunderstorm

Physica, 1952
Synopsis A number of cases has been observed in which the presence of high energy electrons of 10 9 eV is directly recorded during thunderstorms. In one instance on the 3rd of May 1952, a 4 to 6% increase above the mean value of the ionisation was found in 6 different recording instruments.

High-Voltage Phenomena in Thunderstorms

Transactions of the American Institute of Electrical Engineers, 1929
Lightning phenomena are analyzed in the light of laboratory experience with high-voltage phenomena in the atmosphere. Special emphasis is placed on the effect of space charges in producing high local stresses when mobilized through channels of high conductivity caused by high temperatures.

High-Resolution Thunderstorm Modeling

2020
Abstract Since the dawn of the digital computing age in the mid-20th century, computers have been used as virtual laboratories for the study of atmospheric phenomena. The first simulations of thunderstorms captured only their gross features, yet required the most advanced computing hardware of the time.

Thunderstorm Signals at Very-high Frequency and Ultra-high Frequency

Nature, 1955
WHILE signals from distant very-high and ultra-high frequency transmitters were being monitored on June 26, 1954, a thunderstorm occurred in the region of the receivers. The transmitters, which operated at 49, 91, 173 and 492 Mc./s., were some two hundred miles from the receiving site. Fig.
