Why do clouds and precipitation occur near fronts?
The lighter warm moist air behind the front is lifted upward and “overrides” the colder air. As the air rises, it cools, and if enough water vapor condenses, widespread clouds and precipitation develop. As the front gets closer, the clouds thicken and eventually light precipitation begins to fall.
Why does precipitation generally occur along the boundaries between fronts?
As the air rises, it cools and the water vapor condenses to form cloud droplets and eventually, precipitation. Upward motion typically occurs along frontal boundaries as air masses of different densities clash. A less dense air mass is lifted by a more dense air mass, leading to the development of precipitation.
How do fronts cause clouds and precipitation quizlet?
When warm air moves over cold air. The front moves slowly and bring drizzly rain, which is followed by clear and warm weather. When warm air is caught between two cold fronts. The air masses stay together and cause many days of cloudy wet weather.
Why do clouds form along a 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.
Why do clouds form behind the moving 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. The air behind a cold front is cooler than the air in front of it.
How does precipitation develop?
Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the Earth. If a cloud is colder, like it would be at higher altitudes, the water droplets may freeze to form ice. Most rain actually begins as snow high in the clouds.
Which front moves slowly causes drizzly rain and stratus clouds before the front?
With a warm front, boundary between warm and cold air is more gradual than that of a cold front, which allows warm air to slowly rise and clouds to spread out into gloomy, overcast stratus clouds. Precipitation ahead of a warm front typically forms into a large shield of steady rain or snow.
Why do clouds form behind cold fronts?
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.
