What are the atmospheric fronts?

Air masses have different properties: pressure indicators, temperature conditions, wind speed. Narrow transition zones appear between them, separating the two air masses. These zones are called cold and warm atmospheric fronts.
In the warm atmospheric front, warm air advances, and cold air, in turn, retreats.
Accordingly, the formation of a cold atmospheric front is associated with the movement of cold air in the direction of the warm air mass.
Moderate latitudes are the zone where atmospheric fronts are most formed. The reason for this phenomenon lies in serious temperature changes.
