What do we mean by "weather fronts"?

The term "weather fronts" specifically refers to boundaries that separate different air masses, which often have distinct temperature and humidity characteristics. These boundaries can lead to various weather phenomena, such as precipitation, cloud formation, and shifts in wind direction, as the contrasting air masses interact. For instance, a cold front occurs when a colder air mass pushes into a warmer air mass, resulting in potential thunderstorms or sudden temperature drops.

The nature of weather fronts as separators of air masses is crucial in understanding meteorological patterns and predicting weather changes. While high-pressure systems are associated with stable and dry conditions, they do not define weather fronts themselves. Similarly, areas of stable weather conditions and boundaries with consistent rainfall do not encompass the dynamic and changeable characteristics of weather fronts, which are primarily defined by the interactions between different air masses.
