Descending air not allow clouds to form because air rises at low pressures.
Descending air not allow clouds to form because air rises at low pressures.
High Pressure comes down and the clouds are up.
Ascending air typically cools as it rises, leading to decreased humidity. However, if the air is too dry to reach its dew point, condensation cannot occur, preventing cloud formation. Additionally, if the rising air is stable, it may continue to rise without cooling enough to condense moisture, further inhibiting cloud development. Thus, adequate moisture and instability are essential for cloud formation in ascending air.
When air rises it decompresses and cools. The cooling can cause moisture in the air to condense.
clouds form above chimneys as the warm air mixes with the cool air
Clouds are more likely to form when the air pressure is low. Low air pressure is associated with rising air, which cools and condenses to form clouds. High air pressure is typically associated with sinking air, which inhibits cloud formation.
Before clouds can form, air must become saturated with water vapor. This means that the air reaches its dew point, causing the water vapor to condense into tiny water droplets. These droplets then accumulate and form clouds in the sky.
Cumulonimbus, or thunderstorm, clouds form from rising moist air.
water vapors combine together in the air. They form clouds.
