Long range weather forecasting, a brief statement

"Although the purpose of this paper is to discuss longer-range weather forecasting and projection of climate fluctuations, by placing these problems in the setting of the whole spectrum of weather forecasting we can better explain the special problems the longer ranges pose. Public forecasts are regularly issued for periods of from a few hours up to 90 days. There are even some warnings issued with lead times of minutes in the case of tornadoes bearing down on towns and cities. The latter are sometimes disseminated by heroic measures: bulletins interrupting scheduled TV and radio programs, civil defense warning sirens, and police cars cruising city streets"--Page 1.
