|
heat
|
amt energy. joules
|
|
|
|
heat intensity
|
amt of energy passed thru a given area
|
|
|
|
langley
|
1cal/cm^2, heat intensity
|
|
|
|
heat flux
|
amt energy passed thru given area in given period of time
|
|
|
|
watt
|
joule/s
|
|
|
|
radiative heat
|
emission/ absorption of em radiation
everything w temp above abs 0 radiates depends on temperature thermal/black body radiation person=100watt |
|
|
|
sensible heat
|
conduction/convection
|
|
|
|
latent heat
|
evaporation/condensation
|
|
|
|
irradiance
|
heat flux per light wavelength unit
|
|
|
|
wiens displacement law
|
describes relationship between absolute temperature and max energy emission
wavelength of max energy emission is proportionate to absolute temperature inverse relationship t^=wavl down |
|
|
|
short wavelength radiation ex
|
solar radiation
|
|
|
|
long wave radiation ex
|
infrared earth radiation
|
|
|
|
stefan-boltzman law
|
describes relationship between abs temperature of objects and total energy flux integrated across all wavelengths
if temp goes up so does energy flux |
|
|
|
spherical spreading
|
radiative heat flux decreases by 1/r^2 as radiation moves away from suns surface and same amt of power is distributed over progressively larger area
|
|
|
|
!!!!solar constant!!!!!!
|
max possible solar radiative energy flux at the avg earth-sun distance
1367W/m^2 |
for venus it would be larger
|
|
|
conduction
|
slow , solids
energy moves not material |
|
|
|
convection
|
faster
in fluids material moves and bring energy w it eddy and turbulent diffusion** |
|
|
|
surface ocean cools due to___and why
|
evaporation, energetic molecs evaportate
|
|
|
|
does atm warm due to evaporation, why
|
no, chem pot energy not thermal
|
|
|
|
what happens for atm temp to increase, why
|
condensation clouds
h bonds form chem pot -> thermal |
|
|
|
insolation
|
incoming solar radiation
-only source of energy for earth as a whole |
|
|
|
outgoing radiation
|
reflected solar radiation (short wave) and infrared (long wave) emitted by earths atm and surface
|
|
|
|
the atmosphere is heated from ___ more
|
below
important to convection |
|
|
|
3 heats in order of significance
|
latent heat 46.4%
net radiative heat 39.3% sensible heat 14.3% |
|
|
|
enso
|
el nino southern oscillation
pac ocean |
|
|
|
pdo
|
Pacific decadal oscillation
pac ocean 20-30 yr cycle |
|
|
|
amo
|
atlantic multidecadal oscillation
50-90 yrs |
|
