Precipitation

________ occurs when water droplets or ice crystals become large enough to fall due to gravity.

Cumulonimbus

________- Has updrafts (air rising to top) and downdrafts (air sinking to bottom)

Hydrogen bonds

________ provide surface tension (even though its very weak)

Weather

________ is a snapshot, Climate is long- term averages.

polar molecule

Water is a(n) ________- one side is positive, one side is negative.

Hail

________: Liquid water forms and gets carried high by an updraft where it freezes, which repeats and leads to larger and larger and larger ice balls.

characteristic temperature

Air mass- body of air with ________, humidity, and stability (source region)

Fog

________ is a cloud at ground level.

Ice crystals

________ are water droplets forced to the top of the cloud.

Dew point

________- Temperature at which condensation occurs (lower in Tucson than Athens)

Saturation vapor pressure

________ is lower over ice than water of the same temp.

vertical position

Stability is the tendency of an air parcel to remain in place or to change ________.

Humidity

________- Water vapor in the air.

environmental lapse rate

Absolutely Unstable- Happens when the ________ is greater than the DAR, causing the parcel to be warmer (less dense) than the surrounding environment, causing it to continue to rise.

Latent Heat

Comes from solid water (ice) melting into liquid water

Humidity

Water vapor in the air

Cumulonimbus

Has updrafts (air rising to top) and downdrafts (air sinking to bottom)

Hail

Liquid water forms and gets carried high by an updraft where it freezes, which repeats and leads to larger and larger and larger ice balls

Air mass

body of air with characteristic temperature, humidity, and stability (source region)
