This happens because the warm air is lighter (less dense) than the cold air. You often see clouds forming at a cold front. This is because as the warm air rises, it cools and moisture in the air condenses.
As the cold front develops the warm air ahead of the front is pushed up over the top of the cold air. This happens because the warm air is lighter (less dense) than the cold air. You often see clouds forming at a cold front. This is because as the warm air rises, it cools and moisture in the air condenses.
You often see clouds forming at a cold front. This is because as the warm air rises, it cools and moisture in the air condenses. Clouds are masses of cool, condensed air. Fronts can be several hundred kilometres in width. The air behind a cold front is cooler than the air in front of it.
Cold air is more dense than warm air, so when a warm air mass meets a cold air mass, the cold air ends up below the warm air. Once the air has risen, it cools and clouds can form. Weather fronts can cause clouds to form. Fronts occur when two large masses of air collide at the Earth’s surface.
What do clouds come before a cold front?
The cold air will push under warm, moist air, which is usually felt ahead of a cold front the days before it’s arrival. The warm, moist air will rise as the cooler air moves under it, causing thick cloud cover, showers and sometimes thunderstorms.
Why are cold fronts more dangerous than warm fronts?
Describe how cold fronts are more likely to produce severe thunderstorms than warm fronts. The boundary along the cloud front is much steeper than the boundary along the warm front, causing the air in a cold front to rise more rapidly and produce the strong updrafts that cause the storm to become severe.
