The boundary separating two masses of air of different densities, typically resulting in stormy weather.

In meteorology, 'front' specifically refers to the leading edge of an air mass, often bringing significant weather changes.

The story behind the word. The meteorological use of 'front' emerged during World War I, coined by Norwegian meteorologists. They borrowed the military term 'front line' to describe the boundary between two opposing air masses, much like opposing armies meeting on a battlefield. This vivid analogy quickly stuck, becoming a standard term in weather forecasting.
