This article is being published in the book "Geophysical Predictions" (National Academy of Sciences, Washington, D. C., 1978). The book covers predictions of a wide variety of phenomena in the atmosphere, hydrosphere, and solid earth. Just as the book is, this article is addressed to the layman with a science education. It is thus not addressed specifically to the meteorologist, but it contains certain information about the weather services, and the impact of numerical weather prediction on them, that I believe will interest those in the meteorological community who have not had close associations with the service side of our house.
