A front is the boundary at which two air masses of different temperature and moisture ... high winds are absent, is also necessary for the formation of an air mass. ... The first letter, written in lower case, indicates whether the air mass ... Neither mass is strong enough to displace the other, and essentially no movement occurs.
Aug 9, 2013 ... A front describes the boundary between two air masses containing ... If the warm air is relatively dry and stable, precipitation would not be likely ... air masses with different densities when neither is advancing. ...

The boundary formed between these two air masses is a cold front . ... See also Atmospheric circulation; Atmospheric composition and structure; ...
A warm front occurs when a warm air mass advances and replaces a cold air mass. On a ... and cooler air:If we consider two air parcels at the same elevation, the warmer air ... cool to its dew point and condense, initiating cloud formation.
Air masses have fairly uniform temperature and moisture ... Once formed, air masses migrate within the general ... that few if any clouds form over a cP source region. ... arctic front. ... side, with neither encroaching upon the other, a stationary front exists. ❑Fronts may slowly migrate and warmer air is displaced above colder.
Air Mass- extremely large body of air whose properties of temperature and ... thus their characteristics are determined by surface over which they are formed. ... If parcel is colder than its environment, it is denser and will descend, which is stable. ... Stationary Front: Occurs when neither a cold or warm air mass is advancing.
