Warm fronts produce clouds when warm air replaces cold air by sliding above it. Many different cloud types can be created in this way: altocumulus, altostratus, cirrocumulus, cirrostratus, cirrus, cumulonimbus (and associated mammatus clouds), nimbostratus, stratus, and stratocumulus.
Because the warm air cools when it rises above a cold front which forms clouds. A warm front brings gentle rain or light snow, followed by warmer, milder weather. A warm front is when the surface boundary between a warm air mass and a cold air mass it is overtaking.
The Latin word ‘cirro’ means curl of hair. Generally detached clouds, they look like white fluffy cotton balls. From the Latin word for ‘layer’ these clouds are usually broad and fairly wide spread appearing like a blanket.

Warm fronts are responsible for huge weather changes. Before warm fronts arrives, the pressure starts decreasing. It brings rain, snow, or sleet along with it. The types of clouds that appear during a warm front include Nimbus, cumulus, and stratus clouds. There is also an increase in the dew point.
Why do you often see clouds along a cold front?
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.
This of course begs the inquiry “What do clouds come before a cold front?”
The most usefull answer is; 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 do cirrus clouds form ahead of a cold front?
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.
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.
