Why are clear skies and "fair" weather associated with high pressure systems?
High pressure forces water molecules to remain in the gas state, not allowing clouds to form
High pressure forces water molecules to stay near the surface, not allowing clouds to form
High pressure systmes aren't associated with "fair" weather, they are associated with clouds and precipitation
High pressure air is cold and freezes water molecules, creating ice at the surface, not allowing clouds to form
Why are clouds, precipitation, and "bad" weather associated with low pressure systems?
Low pressure forces water molecules to heat up until they reach the dew point temperature.
