a tempurature drop that accompanies a pressure reduction on an air parcel, as when air parcels rise within the atmosphere
a boundary that exists between 2 air masses with different temperatures and/or water vapor concentrations
boundary formed where a cold air mass overtakes and lifts a warm air mass
a boundary between air masses where the warm air mass slides up and over the cold air mass
a nearly motionless boundary between between a cold air mass and a warm air mass. winds blow parallel to the front, but in opposite direction on the two sides of the front.
a boundary that forms when a cold front overtakes a warm front
the temperature above freezing to which air must be cooled to reach saturation
the temperature below freezing to which air must be cooled to reach saturation
a state in which the air is "holding" all of the water that it can at a given temperature
a process by which air reaches saturation by being forced up and over mountains
when air reaches saturation because it has been heated and it rises because its density has been reduced
a visible mass of water droplets or ice crystals that are suspended in an air layer that is not in contact with the ground
a visible mass of water droplets or ice crystals that ae suspended in an air layer that is in contact with the gorund
a ground level cloud formed by night time radiational cooling of a humid air layer. common on clear nights with light winds over damp areas such as rain soaked feilds or wetlands
a ground level cloud formed when a moist, warm air mass moves over a cold surface like a snow pack, a lake, or a ocean
a general name for a ground level cloud that formes when cold air comes in contact with relatively warm water
water drolets formed by condensation of water vapor on a relatively cold surface like grass, cars, etc.
ice crystals formed by sublimation of water vapor on a relatively cold surface like grass, cars, etc.
