Which of the following gases is the most abundant in the Earth's atmosphere?
|
Nitrogen
|
|
Which of the following statements best describes why the Earth has seasons?
|
The Earth's axis is tilted at an angle of 23.5 degrees so that the Northern Hemispheres has less direct sunlight in winter and more direct sunlight in summer.
|
|
Which of the following cities would have the smallest variation in temperature throughout the year? (Hint: Use Google to find their locations)
|
Eugene, OR
|
|
If the tilt of the earth on its axis were 40° instead of 23.5°, at what latitude would the Sun's rays be perpendicular to on the Northern Hemisphere's summer solstice (June 21st)?
|
40°N
|
|
Which two layers of the atmosphere have temperature cooling with height?
|
mesosphere and troposphere
|
|
Which of the following is true with respect to air temperature?
|
warm air rises because it is less dense than cold air.
|
|
Why is the surface pressure always lower in Denver, CO when compared to New York City, NY?
|
Denver is roughly 1 mile above sea level while New York City is at sea level and because pressure decreases rapidly with height Denver will always have lower surface pressure.
|
|
If it is mid-winter in Chicago, IL and the surface pressure at your location builds to 1035 mb, what type of general weather conditions would you expect?
|
clear skies with light winds and generally fair weather conditions
|
|
What would the air pressure be at an altitude where 30% of the atmospheric mass is above you and 70% is below you?
|
~ 300 mb
|
|
A evening arrives and the air temperature drops, what typically happens to the relative humidity? (Assume the dew point temperature remains constant.)
|
it will increase
|
|
True or False. As the temperature of the air decreases, its ability to hold water vapor increases.
|
FALSE
|
|
"Given the temperatures and dewpoint temperatures for the following four cities, which city has the highest saturation vapor pressure?
Boston, MA - Temperature = 60°F, Dewpoint Temperature = 50°F
Lexington, KY - Temperature =86°F, Dewpoint Temperature = 64°F
Boise, ID - Temperature…
|
New Orleans, LA

Your friend - who is also taking ATMS 120 - comes over to hang out. She brings with her an old hair hygrometer she found in her grandmothers attic. You set it up and find that the dew point temperature in the apartment is 50°F. What is the vapor pressure? (Hint: Check out figure 1.9)
|
12.3 mb
|
|
On a summer day in Phoenix, AZ the temperature reached 96°F with a dew point temperature of 32°F. Across the country in Tampa, FL the temperature also reached 96°F with a dew point temperature of 69°F. True or False, it would be much easier to stay cool by sweating in Phoenix than in Tamp…
|
TRUE
|
|
Within what layer of the atmosphere does the rawinsonde (weather balloon) primarily measure the vertical profile of temperature, dewpoint temperature, pressure and winds?
|
troposphere
|
|
During the weather briefings, we have been talking about forest fires in which location?
|
Boulder, CO
