(32 cards)
Wavelength
distance between wave crests/troughs
frequency
wave crests that pass a point per second
blackbody
absorbs and emits all energy
Wiens displacement law
max wavelength = c/T(K)
Stefan Boltzmann Law
E ~ T(K)^4
Inverse square law
E ~ 1/R^2 (r = distance from sun)
Solar constant
solar radiation on atmosphere, perpendicular to beam; ~1.97 cal per cm^3 per min
Callendar effect
theory that climate can be changed by enhancing natural greenhouse gasses
pyranometer
measures intensity of solar radiation
visible light on electromagnetic spectrum
0.40-0.70um
2nd law of thermodynamics
heat flows toward lower temperature
bowen ratio
sensible heating/latent heating
global heat transfer
poleward
thermohaline circulation
density driven movement of oceans
cold air advection
horizontal movement cold air to warm area
c to f
(c x 9/5) +32
btu to cal to joule
1 btu = 251.9 cal = 1055 J
Daltons Law
P(total) = P1 + P2 + . . .
avg sea level air pressure
1.0 kg/cm^2 or 14.7lb/in^2
mb to hPa to Pa
1mb = 1hPa = 100Pa
half of atmospheres mass below
5500m
500mb surface
where half of the atmosphere is above and below, lower in colder air
densest air mass
cold and dry
high pressure weather
usually fair weather, sinking columns, anticyclone, clockwise and diverging winds
