What Happens When Air Masses Collide
All thunderstorms need the same ingredients: moisture, unstable air and lift. … Unstable air forms when warm, moist air is near the ground and cold, dry air is above. Lift comes from differences in air density. It pushes unstable air upward, creating a tall thunderstorm cloud.

What would happen if a mass of cold air ran into a mass of warm air?

A cold front forms when a cold air mass runs into a warm air mass (Figure below). The cold air mass moves faster than the warm air mass. … As the warm air rises, its water vapor condenses. Clouds form, and precipitation falls.

What happens when two air masses collide and the fronts become distorted?

As air masses collide, the boundary between the fronts sometimes becomes distorted by surface features such as mountains or winds. When this happens, bends can happen along the front, and the air begins to swirl. What are cyclones? They are a swirling center of low air pressure.
