Abstract :
A knowledge base has been developed, tested and validated which relates synoptic and mesoscale weather map features, and satellite cloud patterns to the occurrence, height and intensity of elevated ducts which affect radar propagation over ocean and coastal areas. This knowledge base, together with climatology and other objective indicators, is being converted into an expert system for use operationally by users of varying levels of experience
