Q

radiative fog

A

forms via a temp inversion- warm air on top of cool air (commonly from radiative cooling). the cooler air near the surface reaches the dew point while the air above does not

Q

valley fog

A

a form of radiation fog, induced by the presence of hillslopes. the coolaer more dense air flows down slope and settles in a valley

Q

advection fog

A

when warm moist air flows over a cold surface, causing the air parcel to cool to tis dew point.
most common the the coast

Q

upslope fog

A

warm air force upwards due to a physical barrirer, cauing cooling to dew point.
common near coastal regions with mountains near by

Q

nimbus

A

raining cloud

17
Q

cirrus cloud

A

wispy
mostly ice
high cloud
“good weather”

18
Q

cirrostratus

A

sheet like
high cloud
often accompanied by a halo around sun or moon (reflection from ice crystals)

19
Q

cirrocumulus

A

high thin, yet puffy clouds
fish gill like

20
Q

altostatus

A

commonly grey/blue
dim visible light
often confused with cirrostratus

21
Q

altocumulus

A

not think
molted gret =distict from cirrocumulus
BIGGER PUFFS (to cirrocum)
confused with alto stratus

22
Q

stratus

A

uniform grey
lower cloud
covers whole sky

23
Q

one way to form stratus clouds

A

dissipation of fog at low levels

24
Q

cumulus clouds

A

low very puffy while clouds
not think
usually assoaicted with blue skies

25
Q

stratocumulus

A

some grey colouring
low puffy clouds that cover most of the sky (minimal sun peakage)
low cloud

26
Q

nimbostratus

A

a uniform grey cloud
covers the sky
rainnnnn
low. cloud

27
Q

cumulonimbus

A

thunder cloud
upflit can extend into the tropopause. will sop at stratosphere due to temp inverison

28
Q

how are clouds most typically formed

A

from rising air that cools
