- Relative humidity
- compares the actual amount of water vapor in the air(specific humidity) with the maximum amount of water vapor the air can hold at that temperature(its capacity)
- How do you find relative humidity
-
measured in %
specific humidity/capacity then x by 100 (%) - Condensation
- change from water vapor to liquid water
- Evaporation
- change from liquid water to water vapor
- Precipitation
- the falling of any form of water from the air to Earth's surface
- cirrus clouds
- thin feathery or tufted, high, ice crystals
- stratus clouds
- low sheets or layers
- cumulus clouds
- formed by vertically rising air currents, thick puffy masses
- alto
- high
- nimbus
- rain cloud
- How do clouds form?
- air above the surface cools below its dew point
- How do clouds get their shape?
-
shape depends on air movement
horizontal-layers(stratiform)
vertical-upward piles(cumuliform) - 5-6 types of precipitation
- 1-drizzle, 2-raindrops, 3-snow, 4-sleet, 5-glaze, 6-Hail
- drizzle
- fine drops, slowly fall close together
- Raindrops
- larger, farther apart, fall faster
