“…Studies of the radiation of charged or being in external electric field submicron or nanoscale particles oscillating at its own acoustic frequency are of great interest both from the point of view of understanding the physics of such fundamental and beautiful physical effects as ball lightning and St. Elmo's lights 19 , as well as for practical use in radar sensing systems. The presence of electromagnetic radiation from thunderclouds 20 can be associated with the oscillations of charged submicron water droplets, the oscillation frequencies of which are determined by their morphology 21 . The frequency spectrum and radiation intensity of such systems are determined primarily by the size distribution of droplets.…”

The development of new methods for generating pulsed electromagnetic microwave radiation is currently an actively developing area of research. Schemes for microwave radiation generation with optical pumping are of great interest. In this paper we propose and experimentally demonstrate principally new method for photonic generation of microwave electromagnetic radiation. This method is based on the use of radiation of charged submicron particles oscillating at their own acoustic frequency. Laser radiation of the optical range implements an effective buildup of acoustic vibrations of submicron particles forming the system under study, according to the Raman mechanism.

“…Even though tornadic storms are frequently (but not always) associated with unusually high sferics rates at frequencies above 150 kHz [Jones, 1959;Stanford et al, 1971;Taylor, 1973], Taylor [1973] has concluded from his own data and…”

The recent article by Davies-Jones and Golden [1975] is welcome, for it focuses attention upon critical deficiencies in the present knowledge of tornadoes. Several thoughtprovoking points are raised concerning the relationships between thunderstorm electricity and tornadoes that deserve to be discussed. Electrical forces. The authors are justified in doubting that 'electrical forces play a primary role in natural vortex dynamics.' Even in strongly electrified storms the pressure differences that could arise from the action of electrical forces are certainly less than a millibar and can be neglected [Vonnegut, 1963]. It does not follow from this, however, or from the fact electrical energy obviously is unimportant in most of the broad spectrum of atmospheric vortices, that electrical heating could not be a significant factor in the energetics of some tornadoes.

“…1. PulSe rates for the 58-MHz rence of tornadoes was also found by Stanford et al [1971], Lind et al [1972], and Taylor [1973a, b]. In the case of the tornado at 2204, however, we have established that the pulse rate peak preceded the destruction of the power line by the tornado by 2 min, so that the period of high pulse rates does not overlap exactly the lifetime of the tornado.…”

Measurements were made of the radio emissions (atmospherics) from a severe local storm which produced three tornadoes in west Texas on June 2, 1974. The radio data were obtained at a frequency of 58 MHz and were analyzed to determine the pulse rate and the frequency spectrum of the pulse envelopes. The pulse rate was highly variable during the largest tornado, in contrast to the smooth increase as the storm was initially building. Radar data showed a characteristic hook echo.
