The front is the boundary between two or more air masses of different temperatures, densities, and moisture levels. As air masses collide, they do not mix easily due to the differences in their characteristics. This results in a front, which can be classified as either a cold front, warm front, stationary front, or occluded front, depending on the movement and characteristics of the air masses involved. Fronts are associated with changes in weather patterns, such as precipitation, changes in temperature, and shifts in wind direction.
