q Created when warm air displaces colder
air.
q Even though the warmer air advances, it is
displaced aloft.
q This
overrunning process places large amounts of warm, moist air over cooler,
drier air along extensive spatial areas.
q Shallow
horizontal stratus clouds dominate and bring light precipitation to
affected regions
q Frontal
fogs may occur as falling raindrops evaporate in the colder air near
the surface.
