Questions with All Correct
Answers
What are anabatic winds? - Answer- Warm updrafts rising along mountain slopes
- usually more turbulent and irregular then mountain waves
What are thermals? - Answer- The warm air that rises after the sun heats the air on the
ground
- helps provide lift fromt he rising air
What are moutnain waves? - Answer- The oscillating wind that occurs after it travels
over a moutain
- can be fun to soar in but some moutnain waves can "break" causing turbulence
What is Standard Atmosphere? - Answer- - the average variation of air pressure,
temperature and density with altitude
How does temperature change with altitude increase? - Answer- - decreases through
troposhere
- increases through stratosphere
- decreases through mesosphere
- increases through thermoshpere
What are the characteristics of the troposphere? - Answer- - almost all weather occurs
here
- tropopause is about 11 km above sea level
What are the characteristics of the stratosphere? - Answer- - between 11 km and 47 km
above sea level
- top is call stratopause
- statopause is warmer because of good ozone layer
What are the characteristics of the mesosphere? - Answer- - top is called mesopause
- temp decreases again
, What are the characteristics of the thermosphere? - Answer- - temp increases with
height
What are the characteristics of the exosphere? - Answer- - bottom is called exobase
aroud 500-1000 km
- top is about 197,000 km
What is atmospheric stability? - Answer- Refers to whether the air will become or stay
turbulent or become or stay non-turbulent
What is laminar? - Answer- Another word for on-turbulent
- implies smooth flow
What is static stability? - Answer- - simple type of stability
- depends on the temp layering in the atmosphere
- is considered statically stable if cold air is under warmer air
- is considered statistically unstable if warm air is under colder air
What are the conditions for statically stable air? - Answer- - forms near the ground
- calm to light winds
- air is nonturbulent
- can form moutnain waves, fog, or turbulence
What are the conditions for statically neutral air? - Answer- - typically forms in overcast
conditions
- moderate to strong winds
- can create dynamic instability and turbulence
What are the conditions for staticially unstable air? - Answer- - occurs on sunny days
when wind is light
- warm air rise while colder air descends
- thunderstorms can form
What is turbulence? - Answer- Random gusty fluctuations of the wind (vertical and/or
horizontal)
What occurs during light turbulence? - Answer- -slight strain against seat belts
- little or no difficulty walking
What occurs during moderate turbulence? - Answer- - definite strain against seat belts
- objects are dislodged
- difficulty walking
What occurs during severe turbulence? - Answer- - forced violently against seat belts
- walking is impossible
- unsecured objects thrown about
