John,

Data models and formats are hardly about weather ontology.

See the upcoming Universal Ontology of Geographic Space: Semantic Enrichment of Spatial Data:

Rain & snow refer to physical precipitation particles, the precipitation in
bulk, the process that produces the precipitation, storms as events, and
storms as objects.

Cyc's representation of these different, but related things (leaving out
comments and some additional statements) includes:

(isa PrecipitationParticle ExistingObjectType)
(genls PrecipitationParticle Particle)
(genls PrecipitationParticle InanimateObject-Natural)

(isa RainProcess ProcessType)
(genls RainProcess PrecipitationProcess)

(isa SnowProcess ProcessType)
(genls SnowProcess PrecipitationProcess)

(isa Rainwater ExistingStuffType)
(genls Rainwater (LiquidFn Water-Fresh))

(isa SnowMob ExistingStuffType)
(genls SnowMob (SolidFn Water))

(isa Snowflake ExistingObjectType)
(genls Snowflake PrecipitationParticle)
(genls (MobFn Snowflake) SnowMob)

(isa Raindrop ExistingObjectType)
(genls Raindrop PrecipitationParticle)
(genls Raindrop Rainwater)

(relationAllExists outputsGenerated PrecipitationProcess
                        (MobFn PrecipitationParticle))
(relationAllExists outputsGenerated RainProcess (MobFn Raindrop))
(relationAllExists outputsGenerated SnowProcess (MobFn Snowflake))

(isa StormAsObject ExistingObjectType)
(genls StormAsObject InanimateObject-Natural)
(relationAllExists physicalParts StormAsObject CloudInSky)

(isa RainStormAsObject ExistingObjectType)
(genls RainStormAsObject StormAsObject)
(relationAllExists physicalParts StormAsObject CloudInSky)
(relationAllExists physicalParts StormAsObject (MobFn Raindrop))

(isa SnowStormAsObject ExistingObjectType)
(genls SnowStormAsObject StormAsObject)
(relationAllExists physicalParts StormAsObject CloudInSky)
(relationAllExists physicalParts SnowStormAsObject (MobFn Snowflake))

(not (relationExistsAll doneBy PrecipitationProcess StormAsObject))
(comment
 (not (relationExistsAll doneBy PrecipitationProcess StormAsObject))
 "A StormAsObject would include Duststorms, which don't (necessarily)
include precipitation.")

(relationExistsAll doneBy RainProcess RainStormAsObject)
(relationExistsAll doneBy SnowProcess SnowStormAsObject)

(isa StormAsEvent ExistingObjectType)

(isa RainStormAsEvent ExistingObjectType)

(relationAllExists doneBy SnowStormAsEvent SnowStormAsObject)

(isa SnowStormAsObject ExistingObjectType)

This is always a problem for ontologists.  The different meanings have
to be teased apart.

I would not restrict the term "system" merely to physical objects.  But
having multiple clearly defined concepts which different people use that word
for in different contexts, is fine.  They just need different URIs.
