The status of weather modification in 1959 was summarized in the Bulletin of the World Meteorological Organization under the title, Artificial Control of Clouds and Hydrometeors . Tentative conclusions that cloud seeding increased the frequency of lightening discharges under some circumstances and that further tests under controlled experimental conditions be necessary to determine the effects on rainfall were among the year's results of research.

   In 1959, the U.S. Navy demonstrated for the first time that under certain conditions of humidity carbon black [soot] could be used successfully to condense moisture into a thin cloud or to dissipate clouds already in the air, the differing results being dependent upon the different radiation effects under various atmospheric conditions.

   Among other fields of experimental metrology  and weather modification considered and in some cases tested during 1959 were the atmospheric nuclei studies of the National Science Foundation  and the weather bureau,  the electrical  charges on droplets, drop size distribution in clouds and the drop coalescence process.

The last three were studied   extensively in England, the U.S.S.R. and the United  States.

   The physical research laboratory of the United States weather bureau published papers on the aspects of cloud physics that were frequently cited  in U.S.S.R. scientific literature during 1959.

   In 1959 there was discussions about deflecting the warm waters of the Japanese current by building a barrier near Bering Strait, thus sending part of the current into the Arctic basin and warming up polar regions to open them for habitation. Scientists pointed out that until meteorological knowledge  of the natural controls of weather and climate was more adequate it would be folly to undertake such a major change in ocean currents and climate because present knowledge indicated that warming of the Arctic ocean would set off a sequence of changes that would bring on another ice age.
