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

|
|
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
