16
Q

what is the process water cycle budget

A

moisture leaves atmos
water from ablation
run off land to rivers
percolate into aquifer

17
Q

what are examples of fast carbon sinks and pools

A

plant photosynthesis
respiration
decomposition

18
Q

what are examples of slow carbons sinks and pools

A

oceans
gas exchange
ocean sediment long term
continental run off

19
Q

what happens when the air is warmer

20
Q

what are cumuliform

A

flat based
vertical development
air rises freely (convection)
dee point

21
Q

what are stratified clouds

A

later when air mass moves horizontal (advection)
oceans to land

22
Q

what are cirrus clouds

A

high altitudes
tiny ice crystals
no precip

23
Q

what is fog or mist

A

condense at ground
temp inversion and clear night
deposit moisture on veg

24
Q

reasons for cloud development

A

convection condensation
advection condensation
pro graphic condensation
frontal condensation

25
what is convection condensation
vertical movement of air adiabetic expansion
26
what is advection condensation
air mass moves accross cool from warm (dew point)
27
what is orographic condensation
air masses forced to move over obstacles cools as temp decrease
28
what is frontal condensation
warm air mass forces to rise over colder air mass
29
what is a lapse rate
rate of change in temperature observed while increasing altitude
30
what is an environmental lapse rate
vertical temp profile temp decrease with time 6.5C less on average every km
31
what are the types of asia attic lapse rates
dry and saturated
32
what is dry adiabatic lapse rate
dry air cooling rapid condensation 10C every km
33
what is saturated adiabatic lapse rate
rate at which saturated air cools 7C less than DLAR
34
when is the atmosphere unstable
ELR >DALR (air parcel cool faster than environment) cumulonimbus clouds keep rising
