- This also has a similar impact on the governing equations, as one would guess.
- Though the viscosity coeffiecient varies with chemical composition for the
- equations governing the atmosphere, the relative composition of the atmosphere
- remains constant since it is so well-mixed with respect to nitrogen and oxygen
- (which together make up 99% of the components). Trace gases are not important
- for momentum exchange, then, since their presence would not affect the viscosity
- by any appreciable margin.
-
- They do, however, affect the energy exchange, by means involving radiative
- transfer, and this is where the effects of increasing trace gases are most felt.
- Chemical exchanges and release of energy by chemical reactions may or may not
- affect the energy distribution. I'm not sure whether studies have been done
- which have dealt with this.
-
- So for those of you who may wish to question atmospheric sciences in the face
- of a changing atmosphere, you might stop and think about how much is actually
- changing (very little) and what effects these changes have (only with respect
- to energy distribution, which should change the climate/weather, but in ways
- which do not violate previously-used meteorological principles).
