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.
 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.
 heavy zoneHeavySurf is when the significantWaveHeight of the WaterWaves over a SurfZone is greater than 13 FootLength or 4 Meter.
 icingIcing is the process by which Ice is deposited on a %Solid object in polycrystalline form.
 lightningA WeatherProcess which involves a significant release of electricity between two electrically charged regions. One or both regions are within the atmosphere in a &WaterCloud, with the second region sometimes occuring on the ground. [Wikipedia] At the moment, we are modeling electricity as flowing from one region to another. Another way to model it is that it is a change of electrical potential at all points on the path. It would be worth revisiting this term by a specialist in Physics.
 overcast weatherOvercastWeather represents a condition in which more than 70% of the sky is covered with clouds.
 partly cloudy weatherPartlyCloudyWeather represents a condition in which between 30% and 70% of the sky is covered with clouds.
 precipitationPrecipitation is the process of water molecules falling from the air to the ground, in either a liquid or frozen state.
 stormStorms occurs in an area where its Atmosphere is dominated by a LowPressureWeatherSystem with Air moving in MotionUpward.Surface Wind of over 30 KnotUnitOfSpeed and or Precipitation are Likely associated with Storms.
 storm system
 thunderAny instance of RadiatingSound which is caused by an instance of Lightning.
 tsunamiTsunami is the class of highly destructive ocean waves caused by offshore seismic processes.
 waterspoutA Waterspout,is a rotating column of air that occurs over a body of water, usually appearing as a funnel-shaped cloud in contact with the water and a cumuliform cloud.There are two types of waterspout, each formed by distinct mechanisms. The most common type is a weak vortex known as a fair weather or non-tornadic waterspout. The other less common type is simply a classic tornado occurring over water rather than land, known as a tornadic supercellular, or mesocyclonic waterspout, and accurately a tornado over water. [Wikipedia]
 weather frontWeatherFront is the class of weather processes that involve relationships between two air masses. A weather front is a boundary separating air masses for which several characteristics differ, such as air density, wind, temperature, and humidity. Disturbed and unstable weather due to these differences often arises along the boundary. [Wikipedia]
 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 systemWeatherSystems are the movement of WindFlows across the EarthsAtmosphere. These movements are known as LowPressureWeatherSystems and HighPressureWeatherSystem.
 windAny Motion of Air.
