Question #1
What is the largest component of Earth’s atmosphere
A.   Carbon Dioxide
B.   Nitrogen
C.   Water Vapor
D.   Oxygen
Question #2
A temperature inversion is characterized by air temperature that
A.   nobody knows
B.   stays the same
C.   increases with altitude
D.   decreases with altitude
Question #3
It’s a cool and cloudy morning at Long Beach. The temperature is 62 and the dewpoint is 59. A pilot takes off from Long Beach airport and notices the temperature “jumps” to 85 degrees at an altitude of 3,000 ft along his initial ascent where the sun is shining and the sky is a stunning blue above a white ocean of clouds. This weather scene is technically known as a
A.   temperature inversion
B.   sign of convective instability
C.   cyclogenesis
D.   offshore wind
Question #4
The ITCZ or Inter Tropical Convergence Zone is a good example of a
A.   cold frontal system
B.   global equatorial zone
C.   mid latitude cyclone
D.   warm and dry airmass
Question #5
It’s 95 degrees in Glendale and 65 degrees in Santa Monica, given what we have learned so far about weather and local winds what kind of a wind might you expect between Santa Monica and Glendale (choose the best answer)?
A.   land breeze
B.   hurricane
C.   sea breeze
D.   Chinook
Question #6
A sea breeze is an example of
A.   onshore flow
B.   tornado
C.   offshore flow
D.   hurricane
Question #7
The strongest jet stream energy is associated with
A.   equal temperatures globally
B.   cold northern latitudes (Arctic) and warm southern latitudes (equatorial region)
C.   warm northern latitudes (Arctic) and cold southern latitudes (equatorial region)
D.   climate change
Question #8
During the summer the jet stream typically
A.   affects California the most frequently
B.   strenthens and heads toward the equator as temperatures warm up
C.   stays the same as during the winter
D.   weakens and heads back toward the Arctic as temperatures warm up
Question #9
The fact that heat and cold go through fluctuations, with some areas hotter and others colder, some years warmer and others colder and by extension some places drier while others wetter is a result of
A.   increase in global greenhouse gas emissions like Carbon Dioxide
B.   mysterious processes that have no explanation
C.   changes in atmospheric pressure configurations that result in what we call weather
D.   fake news since the weather is always similar
Question #10
When the air is warmer near the surface and colder in the upper atmosphere, oftentimes evident by the development of upward rising cumulus clouds, the conditions are said to be
A.   the result of a temperature inversion
B.   unstable
C.   stable
D.   tectonically active
Question #11
If there is a mid-latitude cyclone with cold air aloft moving in, the temperatures near the surface are warmer than above, there is adequate moisture available for cloud formation, the winds at ground level are coming in from the Southeast at 15 knots, as altitude increases the wind is observed to be increasing as well changing direction to South at 5,000 feet , then Southwest at 18,000 feet with a strength of 60 knots. The Doppler radar begins to pick up on a developing and intensifying “cell” with light green around the edges and yellow, orange and even red toward the middle. If you were a forecaster you would begin to consider the possibility of
A.   tornadoes
B.   a hurricane
C.   a blizzard
D.   Santa Ana winds
Question #12
Los Angeles rainfall has been
A.   too complicated to think about
B.   dramatically decreasing with permanent drought conditions now the rule
C.   going through cycles of some years having more, others having less and others seeing about average
D.   continuously increasing with more rain now than ever before
Question #13
When the temperature and dewpoint temperature are not equal
A.   clouds and fog form
B.   the air is not saturated
C.   the air is saturated
D.   it gets much cooler
