Factors that can decrease the stability of an air mass include warm air rising from the surface, the presence of cold air aloft, and strong wind shear. These conditions can lead to atmospheric instability and the development of severe weather such as thunderstorms.

What are the 3 characteristics of an air mass?
The three characteristics of an air mass are its temperature, humidity, and stability. These factors help determine how the air mass will behave and what kind of weather it is likely to bring.
An air mass takes on its source region's?
An air mass takes on its source region's temperature, humidity, and stability characteristics as it moves across different regions. This can influence the weather patterns and conditions in the areas where the air mass travels.
An air mass's ability to resist rising?
An air mass's stability refers to its ability to resist vertical movement- more stable air resists rising and sinking motion. Stable air masses typically have cooler, denser air near the surface, preventing strong vertical movement. Conversely, unstable air masses are more prone to rising due to warm, buoyant air near the surface.
What does stability mean in terms of air movement?
Stability in terms of air movement refers to the tendency of air masses to resist vertical motion. A stable atmosphere typically has a decrease in temperature with height, which suppresses vertical air movement. Conversely, an unstable atmosphere has the potential for strong vertical motion, leading to the development of thunderstorms and other severe weather.
What are 4 factors affecting air mass?
Temperature: Air masses can be warmer or cooler depending on the region from which they originate. Humidity: The amount of water vapor in an air mass affects its characteristics and potential for precipitation. Stability: The stability of an air mass can influence weather patterns, with unstable air potentially leading to thunderstorms. Source region: The geographical origin of an air mass can determine its properties, such as maritime or continental air masses.
How would temperature and humidity at a given location change when a maritime tropical air mass is replaced by a continental polar air mass?
The temperature would go from being in the 80s and 90s to the 60s and 50s due to the coldness of the polar air. The temperature would decrease. The humidity would decrease also because it goes from being warm and moist to cold and dry.
If the temperature of an air mass increases by 20oc would the relavative humidity increases or decreases?
If the temperature of an air mass increases by 20°C, its relative humidity would decrease. This is because warmer air can hold more water vapor, so the ratio of water vapor present in the air compared to its capacity will be lower, leading to a decrease in relative humidity.
How are temperature and air mass related?
For a given volume and pressure, the mass of the air contained in that volume (density) will decrease as the temperature increases.
What change would air mass modification cause in a continental polar air mass that moves south over central US?
As a continental polar air mass moves south over the central US, it will likely warm up due to contact with the warmer land surface. This process is known as air mass modification and it would result in the air mass becoming less stable and potentially more humid. Overall, the continental polar air mass would undergo changes in temperature, stability, and moisture content.
If you squeezed a balloon and made it smaller would the density in the air would become greater?
Squeezing a balloon would decrease its volume, causing the air particles inside to be more tightly packed together. This would increase the air's density within the balloon.
What happens when you decrease mass in a given volume of air?
The temperature and pressure rise.
What does the symbol on a weather map tell about an air mass?
The symbol on a weather map indicates the characteristics of an air mass, such as temperature, humidity, and stability. By analyzing these characteristics, meteorologists can predict how the air mass will influence the weather conditions in a particular area.

An air mass takes on its source region's?
An air mass takes on its source region's temperature, humidity, and stability characteristics as it moves across different regions. This can influence the weather patterns and conditions in the areas where the air mass travels.
When air bubbles rises in water its volume increases what happens to its mass and density?
The mass of the air bubbles remains the same as they rise in water, but their density decreases. This is because as the volume of the air bubbles increases, they displace more water, causing their density to decrease relative to the surrounding water.
2 chararistics of an air mass?
An air mass is a large body of air with relatively uniform temperature and humidity. It is identified by its source region, which influences its characteristics such as stability and moisture content.
An air mass's ability to resist rising?
An air mass's stability refers to its ability to resist vertical movement- more stable air resists rising and sinking motion. Stable air masses typically have cooler, denser air near the surface, preventing strong vertical movement. Conversely, unstable air masses are more prone to rising due to warm, buoyant air near the surface.
