weather process
WeatherProcess is the broadest class of processes that involve weather, including weather seasons (not to be confused with instances of SeasonOfYear), weather systems, and short-term weather events.
Relationships      
Parents motion Any Process of movement.
Children atmospheric hazingAtomsphericHazing is a WeatherProcess in which the atmosphere of the area is obscured by fine suspended particles of less than 1 Millmeter, causing a reduction in visibilityInMeteorology to be between 2 to 5 kilometres. [text courtesy wikipedia]
 clear weatherClearWeather represents a condition in which less than 30% of the sky is covered with clouds.
 desertificationDesertification is the Process by which fertile land becomes desert.
 droughtDrought is the subclass of WeatherProcess that represents long periods without precipitation, which is damaging to crops, livestock, and human life.
 dust stormDustStorms happen in AridClimateZones or SemiaridClimateZones. They occur when a strong Wind carries particulateMatter or Sand from its underlying Dry surface and deposit it to another Region.
 fogFogging is Water droplets or Ice Crystal suspended in the EarthAtmosphere, causes visibilityInMeteorology to be reduced to less than 1,000 Meter.
 FrostingFrosting is the Process by which a coating or deposit of Ice Crystals form on the surface of Solid Objects.

 weather frontWeatherFront is the class of weather processes that are involve relationships between two air masses, such as a high pressure weather system or a low pressure system.
 weather seasonWeatherSeason is the class of seasonal processes that are characterized by various weather patterns. WeatherSeasons may recur on a regular annual basis, on a different pattern, or irregularly.
 weather systemWeatherSystem is the class of large-scale atmospheric processes that influence weather in a region for 2-5 days.
