Question 1

what is fog

Answer 1

condensation in the lower atmos

Question 2

what are the types of fog

Answer 2

radiative
valley
advection
upslope
mixing
fog drip

Question 3

radiative fog

Answer 3

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

Question 4

radiatve cooling

Answer 4

the emmision of thermal heat from the surface to cool

Question 5

valley fog

Answer 5

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

Question 6

advection fog

Answer 6

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

Question 7

upslope fog

Answer 7

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

Question 8

mixing fog

Answer 8

the mixing of 2 near saturation air parcels at differnet temps

Question 9

fog drip

Answer 9

when the moisture from fog adheres to leaves and needles and drips off.
high source of fresh water (to be included in the water cycle)

Question 10

water are the different ways clouds can form

Answer 10

convection
orographic uplift
convergence
frontal systems
divergence

Question 11

high clouds

Answer 11

7km<
cirro-
wispy due to little water and particle presence

Question 12

middle clouds

Answer 12

2-7km
alto-
commonly formed during weather chnages

Question 13

low clouds

Answer 13

<2km
no prefix

Question 14

puffy clouds

Answer 14

cumulus

Question 15

layered

Answer 15

stratus

Question 16

nimbus

Answer 16

raining cloud

Question 17

cirrus cloud

Answer 17

wispy
mostly ice
high cloud
“good weather”

Question 18

cirrostratus

Answer 18

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

Question 19

cirrocumulus

Answer 19

high thin, yet puffy clouds
fish gill like

Question 20

altostatus

Answer 20

commonly grey/blue
dim visible light
often confused with cirrostratus

Question 21

altocumulus

Answer 21

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

Question 22

stratus

Answer 22

uniform grey
lower cloud
covers whole sky

Question 23

one way to form stratus clouds

Answer 23

dissipation of fog at low levels

Question 24

cumulus clouds

Answer 24

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

Question 25

stratocumulus

Answer 25

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

Question 26

nimbostratus

Answer 26

a uniform grey cloud
covers the sky
rainnnnn
low. cloud

Question 27

cumulonimbus

Answer 27

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

Question 28

how are clouds most typically formed

Answer 28

from rising air that cools
