| layer we live in and its altitude |
|
Definition
| troposphere, about 9 miles high |
|
|
Term
| airplanes fly in the ______ because why? |
|
Definition
| fly in the tropopause because air in the stratosphere does not interact much with the troposphere so we don't want chemicals to get stuck in the strat. |
|
|
Term
| Reason Temp increases as we move upward in the stratosphere |
|
Definition

|
Term
| Reason LA's pollution is so bad. |
|
Definition
| LA is located in a basin. Behind the city are the San Gabriel mountains. Air coming in from the ocean gets trapped in the basin. Sitting over the city most of the year is the N Pacific Anticyclone. |

|
|
Term
|
Definition
| meteorological term for "the notion of reflectivity." Every syrface on the planet has it. |

|
Definition
|
|
Term
| most albedo-- most reflective surface on the planet |
|
Definition

|
Definition
| high latitude locations undergoing a loss of albedo surfaces. |
|
|
Term
|
Definition
| 15-25% reflectivity- results in a lower temp on grass than on asphalt |
|
|
Term
|
Definition
| 30-60%. pure white sand has higher albedo than black sand. |
