“…The major difficulty lies in the many orders of magnitude, both of concentration and size, across which cloud particles of fundamental interest are found. The most successful tool for measuring the large-size end of both the liquid-and solid-particle spectra permits continuous sampling and uses a metal foil on which impinging hydrometeors leave impressions that are functions of the original size and state (solid or liquid) of the particle (Brown, 1961). However, the tedious task of analyzing the impressions of the foil has precluded the full exploitation of the potential of this device.…”

A review of the status of weather-modification research, with emphasis on progress since 1966. The authors stress that 1) the possibility of inadvertent weather or climate modification is rapidly becoming a probability, as human effects on the atmosphere and the surface of the planet grow at an increasing rate; 2) progress in weather modification research continues to be hampered by the prevalent lack of cohesive effort by both theoreticians and experimenters; 3) computers of advanced design and increased capacity will handle atmospheric models of considerably greater sophistication than in the past; and 4) this is a not-to-be-neglected opportunity for interactive research—constant two-way feedback from theory to experiment to theory, with dynamic atmospheric models facilitating each advance. General and specific recommendations are appended concerning areas most urgently requiring research and instrumentation most drastically needing development.

“…Values reported in the literature range from 0.125 gm/cms, NAKAYA & TERADA (1935) for pellets falling from winter stratus, to more than 0.85 gm/cm* for pellets found just above the 0°C isotherm inside cumulus clouds, BRA-HAM (1963). By considering the possibility that the band resulted from the precipitation of a convective turret observed above the altostratus and that a distinct detection threshold established by calibration is known for the foil impaction device, BROWN (1958BROWN ( , 1961, the author tends to favor a rather high density for the pellets. The computed values of water content for levels 1 and 2 assume a pellet density of 0.85 gm/cms.…”

A rationale for weather‐control research

The subject fields of weather control and weather modification are inseparable from the field of meteorology as a whole. The first steps in weather modification must be accompanied by a broadening of man's knowledge of the processes, large and small, that take place in the atmosphere and at its boundaries. Study will be most rewarding, we believe, if it consists of investigation into the various‐sized processes related to natural atmospheric instabilities, colloidal, convective, and baroclinic, and to the linkages between them. Enquiry into these and other interesting or pertinent meteorological phenomena seems most likely to reward effort if the techniques and tools at the disposal of the meteorological community are used not singly, but in concert, and if the efforts made are not single‐minded, but coordinated. To this end a set of promising specific areas for research are listed not with the idea that this set is a definitive one, but rather as a rational beginning within the thesis developed in this study.
