Weather Attributes


#$Raininess   raininess
A specialization of #$PhysicalAttribute. Each instance of #$Raininess is a measure of the intensity with which it is raining at an instance of #$OutdoorLocation (q.v.). (At the low extreme, it is not raining at all.) Degrees of raininess may be represented qualitatively (e.g., #$Rainy), or using #$GenericValueFunctions. The raininess of a location is indicated with the predicate #$raininessOfRegion.
