 | | Within this layer, temperature increases as altitude increases; the top of the stratosphere has a temperature of about 270 K, just slightly below the freezing point of water. |
 | | An interesting feature of stratospheric circulation is the quasi-Biennial Oscillation (QBO) in the tropical latitudes, which is driven by gravity waves that are convectively generated in the troposphere. |
 | | Chloroflorocarbons are a compound of clorine, florine, and carbon Because CFCs are stable, inexpensive, non-toxic, non-flammable, and not corrosive, they are used as propellants, as refrigerants, as solvents, etc. However, it is this stability that causes these CFCs to persist within the environment. |
