types of condensation
dew: condensation on earths surface White frost: sublimation on earths surface Rime: supercool fog droplets that freeze on contact fog: clouds near ground
dew point
The temperature at which condensation begins
Normal rain pH
about 5.6
specific humidity
mass of vapor per volume of air
4 movements
1.moves from west to east 20-30 mph 2. counterclockwise in NH 3. cold fronts faster 4. warm fronts slower
midlatitude anticyclone
huge areas of high press and sinking and diverging air
2nd cloud name
shape
cold front
cold air mass into warm air mass
80% of tornadoes occur
along cold fronts (squall lines) most in US in tornado valley
Precipitation
Any form of water that falls from clouds and reaches Earth's surface.
absolute humidity
mass of vapor per mass of air
convective lifting
warm air rises and cools to dew point
if first and last name are similar use second name
humidity
The amount of water vapor in the air
stationary front
neither air mass is advancing
stratus clouds
layered sheet like clouds from gentle rising air
sleet
half frozen rain
Types of fog
- Radiation: Ground cooling at night - Advection : warm air blowing over cold surface - Orographic: Air forced to rise up mountain - Evaporation: cold air blowing over warm surface
cumulus clouds
puffy white clouds that tend to have flat bottoms
snow
made from sublimation
Air masses
mass of air with characteristics. 100 mi diameter
Strato Clouds
low clouds 6500ft
clouds 1st name
Height
Virga- rain
evaporated before hitting ground
Nimbo/Nimbus
rain
occluded front
cold air mass pushes all warm air up
midlatitude cyclone
huge cyclonic storms in midlatitudes 1000 mi diameter
Air Mass Letter Codes 2nd
E= equatorial very warm T= tropical warm P= Polar cold A= arctic very cold
Bergeron Process
ice crystals attract moisture from droplets
front
A boundary between two air masses
alto clouds
middle level clouds 6500-19700ft
warm front
warm air into cold air mass
vapor pressure
force exerted by water vapor
acid rain
deposition of acid materials on surface
squall line
line of thunderstorms along a cold front
relative humidity
ratio of the amount of water vapor in the air and how much the air can hold at a given temp
rain
forms by the collision of cloud droplets
Saturation
100% relative humidity
Air Mass Letter Codes 1st
c = continental m = marine
acid rain pH
less than 5.6
warm air holds more water vapor than cold air
true
Tornadoes
300mph winds 100mb+ pressure storm is 1/4 mi diameter
Atmospheric Moisture
liquid water: cloud droplets Ice: ice crystals in clouds Water vapor: colorless/oderless gass
frontal lifting
air forced to rise along a front
cirrus clouds
wispy clouds
cumulonimbus clouds
Large clouds that often produce thunderstorms are called
lifting condensation level
altitude at which condensation occurs
cirro clouds
high clouds 19700 +
orographic lifting
air rise over mountain
glaze
supercool rain that freezes on contact
