a temperature drop that accompanies a pressure reduction on an air parcel, as when air parcels rise within the atmosphere.
a boundry that exists between air masses with different temperatures and/or water vapor concentration
a lkarge volume of air with uniform temperature and water vapor concentration
a boundry in which a cold air mass overtakes a warm air mass
a boundry in which a warm air mass overtakes a cold air mass
a nearly motionless boundry that forms between a cold air mass and a warm air mass. Winds blow parallel to the fron but in oppisite direction on the two sides of the front
a boundry that forms when a cold front overtakes a warm front
the temperature above freezing to which air must be cooled to reach saturation
a temperature below freezing ti which air must be cooled to reach saturation point
a state in which the air is holding all of the watter that it can at a given temp.
a process by which air reaches saturation point by being forced up and over mountains
when air reaches saturation becasue it has been heated and it rises becasue its density has been reduced

a visable mass of water droplets or ice crystals that are suspened in an air layer that is in contact with the ground
a ground-level cloud formed by nightime radiational cooling of a humid air layer. common on clear nights with light winds over damp areas such as rain socked feilds or wetland
a ground level cloud formed when moist warm air mass moves over a cold surface like a snow pack, lake, or ocean
a general name for a ground level cloud that forms when cold air comes into contact with warm air
water droplets formed by condensation of water vapor on a relitvely cold surface like grass
ice crystals formed by sublimation of water vapor on a relitlively cold surface like grass
