State of the Atmosphere
Moisture in Atmosphere
Temperature to which air must be cooled at constant pressure to reach saturation
Amount of moisture present
Amount of moisture possible
Surface on which water droplets can form. Smoke or dust particles can act as condensation nuclei
Cloud formation as a result of wind moving air into a mountain. This moves the air upward.
The ability to resist rising
The heat exchanged during a phase change.
Form high in atmosphere, made of ice crystals, appear as thin, white, feathery clouds
Flat-based, puffy white clouds with cauliflower appearance on top. Extends vertically several thousand ft.
3 main cloud types
Layered cloud that covers most of the sky. Forms at low altitudes. Often gray.
High, thin clouds that give sky a milky white appearance.
Delicate clouds forming in bands a ripples. These rare clouds form when cirrus clouds degenerate.
Clouds of intermediate height, having blue-gray appearance. Composed of ice crystals and water.
Have oval shapes, colored white with gray undersides. May produce mild precipitation.
Often associated with steady precipitation. Can occur in thick, continuous layers.
Can cover the sky in dark, heavy masses. Form irregular masses close to the ground.
Puffy, white cloud. Towering clouds that extend upward to heights of 2-5 miles. Cause thunderstorms
