over Alaska

across the north pole

over the equator

Flag question: Question 13

13. The jet stream in the previous chart is what would normally be expected during 

Group of answer choiceswinter

summer

climate change

hurricane formation

Flag question: Question 14

14. During the winter the jet stream typically 

Group of answer choicesdisappears

gets stronger and further south

gets weaker and further north

is confined to the Arctic

Flag question: Question 15

15. The strongest jet stream energy is associated with 

Group of answer choiceswarm northern latitudes (Arctic) and cold southern latitudes (equatorial region)

cold northern latitudes (Arctic) and warm southern latitudes (equatorial region)

equal temperatures globally

climate change

Flag question: Question 16

16. California’s rain and mountain snow that is common during the winter season is usually a result of 

Group of answer choicesstorms being delivered by a strong jet stream

Santa Ana winds with strong high pressure

the sea breeze

weak jet stream energy and warm Arctic temperatures

17. During the summer the jet stream typically 

Group of answer choicesaffects California the most frequently

strenthens and heads toward the equator as temperatures warm up

weakens and heads back toward the Arctic as temperatures warm up

stays the same as during the winter

Flag question: Question 18

18. Here is a chart of Arctic sea ice concentration since the early 2000s until 2019. There is an abrupt curve exhibited on this graph with Arctic sea ice volume sharply declining (and a lot of ice melting) between April until September. This is a result of  

Group of answer choicesmanipulated data as there has not been any Arctic sea ice in the summer for nearly a decade

the sun being directly overhead and shining on the Arctic continuously with 24-hour sunlight and no sunset and no night for 6 months straight at the North Pole

global warming also known as climate change

instrumentation error as it is very difficult to get accurate readings that far north in the world

Flag question: Question 19

19. Some of the most extreme weather to have ever hit California with multi-decades-long drought, searing heat characterized by unbelievable temperature readings (133 degrees in Santa Barbara), devastating floods that left huge parts of the state under water for up to 6 months and more happened during the

mid 1800s

early 1900s

late 1990s

20. 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

Group of answer choicesmysterious processes that have no explanation

fake news since the weather is always similar

increase in global greenhouse gas emissions like Carbon Dioxide

changes in atmospheric pressure configurations that result in what we call weather

Flag question: Question 21

21. 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

Group of answer choicestectonically active

the result of a temperature inversion

stable

unstable

Flag question: Question 22

Flag question: Question 23

23. On a particular day not too long ago a cold pocket of air aloft, characterized by temperatures of -23 C (-9 F) at 18,000 feet moved over southern California, associated with a late-season trough of low pressure. During the late morning to early afternoon temperatures were still in the mid to upper 50s under overcast skies with drizzle and even light rain falling around downtown Los Angeles. Temperatures were similarly cool and it was also cloudy in the San Fernando Valley. Meanwhile, skies were partly cloudy across the high desert were temperatures were generally in the mid to upper 60s at the same time. Given this information where would you expect the greatest instability was developing?

Group of answer choicesLos Angeles basin

nowhere

San Fernando Valley

high desert

Flag question: Question 24

24. Where would you expect the greatest chance of thunderstorms to form that afternoon? 

Group of answer choiceshigh desert

nowhere

Los Angeles basin

San Fernando Valley

Flag question: Question 25 pts

25. 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

Group of answer choicestornadoes

a hurricane

Santa Ana winds

a blizzard

Flag question: Question 26

26. Los Angeles rainfall has been 

Group of answer choicesdramatically decreasing with permanent drought conditions now the rule

too complicated to think about

continuously increasing with more rain now than ever before

going through cycles of some years having more, others having less and others seeing about average

Flag question: Question 27

27. The notion that tornadoes do not occur in California is 

Group of answer choicessomething that everyone knows because this is earthquake territory

true because the jet stream stays away

true because there are mountains and valleys

a myth

it gets much cooler

the air is saturated
