JOURNAL OF WEATHER MODIFICATION Volume 39

Now Available: All 39 Issues of THE JOURNAL OF WEATHER MODIFICATION

Published by THE WEATHER MODIFICATION ASSOCIATION, founded in 1951 to encourage experimentation and discussion on human intervention in the natural processes of the atmosphere with special emphasis on augmentation of rain and snow, and suppression of hail and fog.

The JOURNAL OF WEATHER MODIFICATION, published since 1969, has documented major and minor developments in this important field. The 36 issues to date include articles by most of the leading theoreticians, experimenters and commercial operators throughout the world. Published once a year during its first six years, the Journal appeared twice during 1975 and again in 1976. Volume 7, No. 1, included 19 papers on operational programs, public opinions, and the progress of several research projects. The issue was dedicated to Marion Nelson Bruce, a true American pioneer who was strongly influential in the development of modern cloud seeding technology in South Dakota. Volume 7, No. 2, contains papers on hail suppression from the first WMA meeting outside the U.S., at Calgary, Alberta, in September 1975.

Volume 8, No. 1, contains nine papers on a wide variety of weather modification subjects including inadvertent modification, cloud seeding experiments, hail suppression, and nuclei. Volume 8, No. 2, was a special Silver Anniversary issue dedicated to Dr. Vincent J. Schaefer, the discoverer of the use of dry ice as an ice nucleating material in 1946 and the "father" of modern cloud seeding science and technology. Volume 9 contained 18 papers on a broad range of subjects from inadvertent weather modification to operational programs, social issues, and research programs. Volume 10 was distributed at the Spring Meeting in Tucson, Arizona, April 1978, and contains 9 papers on projects outside the U.S. and 11 papers on environmental aspects of silver iodide, a summary of U.S. programs in CY1976 and 1977, USBR Skywater information, and a few legal aspects of weather modification.

Volume 11 was distributed at the Spring Meeting in Reno, Nevada, April 1979. This was the first issue of JWM with sections for both reviewed and non-reviewed papers. The volume contains information on hail suppression, numerical simulation, radar applications, economic aspects, and a listing of projects conducted in the U.S. during CY1978. Volume 12 was circulated at the Spring Meeting in Santa Barbara, California, April 24-25, 1980. A significant landmark was the addition of a color cover. Five papers appeared in the reviewed section and 11 in the non-reviewed section. Volume 13 was available at the Spring Meeting in Ft. Collins, CO, 9-10 April 1981. Publication was large at 262 pages. There were 18 reviewed and 8 non-reviewed papers covering programs in the U.S. and seven other countries. Volume 14 contained 12 papers in the reviewed section; 7 dealt with projects in countries outside the U.S., China, Chile, and southeast Asia and were newcomers to the Journal. The new Certification Program became an official part of WMA.

Dr. Bruno Federer passed away in December 1982 and his accomplishments were noted in Vol. 15. This issue carried 14 reviewed papers from the U.S., France, Italy, and Yugoslavia. The decline of weather modification operations and research in the U.S. was noted along with the increase in worldwide activities. Volume 16 was circulated at the meeting in Bismarck, ND, July 1985. It carried 8 reviewed and 4 non-reviewed papers, plus all of the general information material on projects at national and international levels. The issue was dedicated to Mr. Olin H. Foehner. Volume 17 noted the first time in the 35-year history of the WMA that a meeting was organized in any country beyond the U.S., Canada, and Mexico. Special appreciation was extended to the hosts in France. Ten reviewed papers and 3 non-reviewed papers were published. Volume 18 carried 27 reviewed papers with several coming from the various groups in France following the 1985 WMA Meeting in Clermont-Ferrand and Toulouse. The new WMA International Award evolved from this meeting.

Volume 19 was distributed at the April 1987 Annual Meeting in Albuquerque, New Mexico. This issue included 17 reviewed papers covering such subjects as precipitation augmentation, hail suppression, program design, and numerical simulations. The international aspect was furthered by a paper from China. Volume 20 included 13 papers covering the subjects of liquid water, ice nucleation, crop production, hail suppression, results from operation programs, and legal aspects. It was distributed at the annual meeting held at Costa Mesa in April 1988, and dedicated to Abe Gagin, a strong force in weather modification at the international level. Volume 21 contained 14 reviewed papers on a broad range of topics from operational programs to cloud models. A major topic at the annual meeting held at Park City, Utah, in May 1989, focused on Weather Modification in the 1990s, including future strategies for the Association's Journal.

Volume 22 continued the tradition of a color cover and included 19 reviewed papers and 3 non-reviewed articles on a variety of scientific research programs and operational projects in the U.S. and other countries, plus a summary of cloud seeding activities in the U.S. as tabulated by the Dept. of Commerce. It was the largest issue since 1981 and was distributed in May 1990 at the Annual Meeting in Sparks, Nevada.

Volume 23 commemorated the 40th Anniversary of the WMA and the 23rd year of Journal publication, all 23 years under the editorship of Thomas J. Henderson. The volume contained 9 reviewed papers on various aspects of applied weather modification. The cover and several photographic pages illustrated some of the individuals who played a strong role in the formative years of the Association. A eulogy was included for Dr. Patrick Squires, a pioneer in atmospheric science, who passed away on 15 November 1990.

Volume 24 contained 11 reviewed papers and 3 non-reviewed articles. The cover photos were from Utah and reflected activities and scenes related to 3 papers discussing the Utah Federal/State cooperative research program sponsored by NOAA. Volume 25 contained 7 reviewed papers and 2 non-reviewed articles. Three papers were related to the Illinois State Water Survey's 1989 exploratory cloud seeding experiment (one modeling and two analysis papers); two papers, to winter orographic situations; one paper presented an analysis of hail suppression cloud seeding effects on weather observations in Yugoslavia; and one paper reviewed some of the consequences of the 1972 Rapid City, SD flood. Copies of the WMO, AMS, and WMA statements regarding weather modification were reproduced for the perusal of the membership. Cover photos were provided by Bruce Boe. A tribute to Wilbur Brewer's retirement was provided by Bruce Boe with a few "ancient" related photos furnished by Tom Henderson.

Volume 26 was dedicated to the memory of Vincent J. Schaefer (1906-1993). Mr. Thomas J. Henderson provided a nice photo-history for this purpose. Fifteen articles were included in Volume 26 (14 reviewed, 1 non-reviewed), and other topics made up the issue. A good representation from both the U.S. and other countries was included. The cover photo was provided by T. Henderson. Thanks to Ward for his input. Volume 27 contained 6 reviewed papers and 3 non-reviewed articles.
