Cloud Physics and Cloud Seeding

Excerpt

Before 1946, few meteorologists were interested in changing the weather. Most of them were concerned with observing, explaining, and forecasting various types of conditions. Not until Vincent J. Schaefer and Irving Langmuir conducted some simple, but dramatic, experiments did scientists begin to realize that it was possible to modify certain types of cloud systems.

Over the last fifteen years we have been trying to develop schemes not only to modify, but also to control the weather. To date the progress has been somewhat disappointing. But in the course of carrying out weathermodification studies, we have learned a great deal about the natural processes of cloud and rain formation.

The realization that it was within the realm of possibility to increase rainfall, suppress damaging hail, and alter the course of severe storms stimulated basic research activity all over the world. As a result, our knowledge of atmospheric phenomena is much greater today than it was only a decade ago. There still are many aspects of the problem that are shrouded with various degrees of uncertainty. However, as continued research pierces through the fog, and we learn more secrets of nature, it seems inevitable that we will learn how to modify and control the weather.

The number of atmospheric scientists working on this problem is distressingly small in view of its tremendous importance. More vigorous and imaginative people are needed. History has shown that some of the greatest . . .
