Title: Rule-based systems for visibility forecasts
Description: Zeus, a prototype rule-based system for forecasting visibility, was developed and tested at three locations along the East Coast. Evaluation of this expert system and further studies at AFGL have led to the conclusion that, although the usefulness of such a system has been demonstrated, a more fundamental approach to the representation of the knowledge base will have to be taken if such systems are to be deployed Air Force-wide. A discussion of the structure of a meteorological knowledge-base and an outline of how a generic fog forecast system might be developed are presented in this report.
