|
|
What is the lowest layer of the earths atmosphere? |
Troposphere |
|
|
What is the transition boundary between the troposphere and the stratosphere? |
Tropopause |
|
|
What layer of atmosphere extends from the tropopause up to 31 miles above the earths surface? |
Stratosphere |
|
|
The stratosphere is a stable layer devoid of _________ weather. |
Significant |
|
|
In the troposphere a increase in temperature with altitude is abnormal and defined as ___________. |
Inversion |
|
|
The _______ layer of the early atmosphere contains almost all clouds and precip, air pressure and density decrease with altitude, and temperature generally decrease with altitude. |
Troposphere |
|
|
A hypothetical vertical distribution of the atmospheric temperature, pressure, and density, which by international agreement is considered to be representative of the atmosphere for pressure-altimeter calibrations and other purposes. |
Standard atmosphere |
|
|
Standard atmosphere is used for what four purposes: |
Pressure altimeter calibrations, aircraft performance calculations, aircraft design, weather-related processes |
|
|
Relatively strong winds concentrated within a narrow, horizontal band in the upper tropopause: |
Jet stream |
|
|
Two commonly identified jet streams: |
Polar jet stream, subtropical jet stream |
|
|
Which direction does the jet stream flow? |
West to east |
|
|
When are jet steams the strongest and why? |
Jet steams are associated with boundaries between hot and cold air, these boundaries are most pronounced during the winter and they are the strongest. |
