Chapter 3 Concepts Flashcards
Culprits ozonehole
N2O, CFC’s
Worst culprits greenhouse
H2O, CO2, CH4, N2O, O3, less: CFC, HFC
Stralingsforcering
Aandreven klimaat door straling
Wet van wien
To work out peak wavelengths
Amax x T = kw.
Hoogste golflengte x Temp straler = constant van wien.
GWP
Global warming potential
CO2 1
SF6 23900 Lange levensduur
Wet van Stefan-Boltzman
To work out how much energy is radiated per second.
P = oAT4
P: stralingsenergie p second door straler
o: stefan boltzman constant
A: Area. Oppervlak straler
T: temperature
Albedo
Energy reflected (earths reflection of sun’s energy is 0.3)
Stralingsbalans
Energy radiated by earth equals energy absorbed by earth.
Thermohaline circulation
Cold salty heavy water, drives conveyor belt
NADW
Noordatlantische diep water
Zwaar water, dreeft conveyor belt, takes cold away from Europe and sucks in the warm gulf stream.
Stralingsevenwicht
Also stralingsbalans 0 is
Azoren
Semi permanent high pressure region
Name 3 positive feedback mechanisms
Albedoterugkoppeling
Waterdampterugkoppeling
Respiratieterugkoppeling
Name 2 negative feedback mechanisms
Dimethylsulfideterugkoppeling maar niet significant.
CO2 fertilisatieterugkoppeling maar..
1 feedback mechanism unknown
Wolkenterugkoppeling
Wintersmog causes
Fuel burning (oxidation)
Wintersmog primary pollutants
CO2, CO, C, CH4, PAK, SO2
Wintersmog secundaire pollutants
Zwavelzuur
Zomersmog primaire pollutants
NOx, NMVOS
What does extra NMVOS cause?
Extra NO2, extra O3
Zomersmog secundaire pollutants
O3, HCOH (formaldehyde)
