Rising warm air cools, resulting in cloud formation and rain. Why does rain occur near a warm front? Rising warm air cools, resulting in cloud formation and rain.

What causes precipitation to happen?
Water droplets may grow as a result of additional condensation of water vapor when the particles collide. If enough collisions occur to produce a droplet with a fall velocity which exceeds the cloud updraft speed, then it will fall out of the cloud as precipitation.
What conditions are necessary for a parcel of air to rise relative to other air in the atmosphere?
Why would a parcel of air rise relative to other air in the atmosphere? A parcel of air will rise if it has a higher density than the surrounding air. A parcel of air will rise if it has a lower density than the surrounding air.
What weather causes precipitation?
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.
Weather Basics: Clouds And Precipitation
What factor is most important for determining the density of a parcel of air?
Pressure, temperature and humidity all affect air density. And you can think of air density as the mass of air molecules in a given volume.
How is precipitation produced in a cloud quizlet?
results from the cooling (usually by uplift) of moist air so that condensation, coalescence and the ice crystal mechanisms occur. increases in water vapor content, uplift and condensation, and ice nuclei tend to favor precipitation formation. affects the quality of the precipitation water.
What will happen to a parcel of air as it rises?
What will happen to a parcel of air as it rises?.
Our Changing Atmosphere Lecture 11 - Clouds And Precipitation
What causes a parcel of air to rise?
That force is 'gravity'. Gravity's role is its pull of cooler, denser air toward the earth's surface. As the denser air reaches the earth's surface it spreads and undercuts the less dense air which, in turn, forces the less dense air into motion causing it to rise.
What will happen to a parcel of air as it rises in the atmosphere?
The air parcel expands as it rises and this expansion, or work, causes the temperature of the air parcel to decrease. As the parcel rises, its humidity increases until it reaches 100%. When this occurs, cloud droplets begin forming as the excess water vapor condenses on the largest aerosol particles.
Clouds And Precipitation
Do all clouds produce precipitation?
We know that not all clouds produce rain that strikes the ground. Some may produce rain or snow that evaporates before reaching the ground, and most clouds produce no precipitation at all. When rain falls, we know from measurements that the drops are larger than one millimeter.
What causes precipitation?
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.
