Atmospheric Science Concepts

This group collects the Meteorology subcategory's members that describe a general meteorological process or concept rather than one named storm, light phenomenon or daily cycle point: precipitation and evaporation as the two halves of the water cycle relevant to weather, atmospheric optics as the umbrella discipline the subcategory's optical-phenomena group belongs to, and terms such as twinkling, cold drop and earthlight that name a general effect rather than a single event. This is the subcategory's own conceptual-vocabulary group, smaller than its named-phenomenon groups.
