Weather Fronts/Systems

So before I start this, i'm going to describe the different kinds of front types. There are two different words used within meteorology to describe weather around a frontal zone.

Cold fronts ; Cold fronts can produce sharper changes in weather and move up to twice as quickly as warm fronts, since cold air is denser than warm air and rapidly replaces the warm air preceding the boundary.

Warm fronts; Warm fronts are at the leading edge of warm air mass, which is located on the equator,  and lie within low pressure than cold fronts. A warm front moves more slowly than the cold front which usually follows because cold air is denser and harder to remove from the Earth's surface.

So predicting weather with the weather fronts shows the different air masses, hot & cold, dry & wet, it shows the different masses that go around.
