Term
|
Definition
| wind dilutes pollution concentration, good for locals, bad-hard to pin location of pollution |

Term
|
Definition
stable air-no vertical motion, stagnant or horizontal, fanning
low alt. unstable air - fumigatio, spreads below inversion layer
unstable- goes wherever, usually looping due to waves in air |
