How does stability affect the vertical development of Cumuliform clouds?
How does stability affect the vertical development of cumuliform clouds? Stability affects the vertical development of cumuliform clouds because stable air suppresses vertical motion whereas unstable air enhances motion, convection, and expansional cooling which favors the development of cumuliform clouds.
How is the stability of air determined quizlet?
Stability is determined by comparing the density of air parcel to the environmental air surrounding the parcel. Air parcels displaced upward that become more dense than their environment will return to their original position indicating a stable environment.

When elevated terrain such a mountain range causes air to rise this called a group of answer choices?
When elevated terrain such as a mountain range causes air to rise this is called what? Air masses are typically at least 1 000 miles (1 600 km) wide and several miles thick. Orographic lifting: This phenomenon occurs when an airflow encounters elevated terrains such as mountain ranges.
How is stability related to the formation of clouds?
Stability & Cloud Development. Cloud development is linked closely with the concept of stability, i.e., the tendency of air to rise. Although several factors determine whether or not clouds will form, the stability of the atmosphere is far and away the single greatest indicator of cloud formation.
Which clouds are stable and unstable?
The words to distinguish between clouds produced by instability and other clouds are stratiform for clouds forming in a stable layer and convective clouds for clouds developing in an unstable environment. Convective clouds have vertical development and often extend through a significant depth of the troposphere.
What clouds form in a stable atmosphere?
Any clouds that form as a result will be thin and horizontal such as cirrostratus, altostratus, nimbostratus, and stratus clouds. All of these cloud types are associated with stable air.
How is the stability of air determined?
Stability is determined by comparing the temperature of a rising or sinking air parcel to the environmental air temperature. Imagine the following: at some initial time, an air parcel has the same temperature and pressure as its environment.
Can you have 100 humidity without rain?
Must it be raining when the humidity reaches 100%? However, near 100% relative humidity, you can get water vapor condensing into very small water droplets to form clouds, including fog near the surface. Also, the relative humidity at the ground does not have to be 100% to get rainfall.
Does rain lower humidity?
When it rains, it will increase the relative humidity because of the evaporation. The air where the rain is falling may not be completely saturated with water vapor. However, the longer it rains, the more the humidity will increase because of the air constantly drawing the water.
What types of clouds and precipitation if any form when stable air is forced aloft?
Conditional instability is when the air is stable for an unsaturated parcel of air and is unstable for a saturated parcel of air. What types of clouds and precipitation, if any, form when stable air is forced aloft. The clouds are typically wide spread and are not very thick, they can cause light precipitation.
What is cloud stability?
How do I know if my air parcel is stable or unstable?
The clearest way to observe the difference between a stable and an unstable air mass is to look at the clouds: A stable atmosphere will have largely flat layers of cloud which, although they may exhibit some lumpiness, will not extend far upwards. There may be several such layers or occasionally, clear skies.
What kind of clouds are stable?
How do you tell if a cloud is stable or unstable?
