Term
| Describe the characteristics of the troposphere, tropopause, and stratosphere. |
|
Definition
troposphere- surface through 55,000 ft over equator and 28,000 ft over poles-- where most weather occurs
tropopause is a transition zone between the troposphere and stratosphere-- the temperature in this zone is isothermal-- the jet stream is right below the tropopause
the stratosphere is characterized by increasing temperature with increasing altitude-- there is a general lack of weather, the air is thin, and this makes for excellent flying |
