question
Using the insolation diagram, name the correct sequence of surface pressure zones associated with latitude zones. Start from the equator and move toward the poles.
answer
low pressure, high pressure, low pressure, high pressure
question
Regarding pressure, latitude, and water vs land.
answer
air pressure is high over oceans at 30° because descending air warms less over the cool oceans
question
If a gas cools under constant pressure, the molecules within it have ______ kinetic energy (motions) and can therefore _______________.
answer
less; be packed into a smaller volume
question
Urban areas heat up more rapidly than surrounding countryside. This can result in
answer
low pressure over urban areas with polluted air flowing aloft and then the polluted air sinking over the surrounding countryside.
question
A true difference between north and south polar areas is.
answer
North Pole is over ocean, South Pole is over land.
question
"N" on the globe represents the northern hemisphere; "S" on the globe represents the southern hemisphere; ITC stands for the Intertropical Convergence Zone. Where will the ITC shift in July?
answer
N
question
Which of the following best describes air circulation at high latitudes?
answer
Cold dense air sinks at the poles, flows outward away from poles, and rises between 60 and 45 degrees latitude.
question
To create a sea breeze
answer
the warm air over the land rises, creating low pressure. Cool air over water sinks, creating high pressure. This creates an onshore breeze.
question
Which of the following statements is true regarding the relationship between air pressure and altitude?
answer
as one moves up in the atmosphere, pressure decreases, as one moves closer to the earth's surface, pressure increases
question
The Hadley cell is characterized by.
answer
low pressure, rising air over the equator; high pressure, sinking air at 30°N and 30°S.
question
The less mass an object has, the stronger the Coriolis effect will be for that object.
answer
False
question
In accordance with the pressure gradient
answer
air is more tightly packed in high pressure zones and moves toward low pressure zones.
question
A parcel of air at the surface is heated which expands the air and increases the parcel's volume. If the same number of air molecules occupy the greater volume, density decreases. The increase in volume results in lower pressure. What will happen to the air surrounding this parcel?
answer
denser air flows in to replace the rising air
question
The Coriolis effect is the apparent deflection in the path of a moving object due to
answer
the rotation of the earth
question
An important property of water is its ability to act as a good solvent. This could best be explained by water's
answer
polarity
question
Convergence resulting in rising atmospheric motion at the surface can occur in all of the following settings EXCEPT
answer
air moving from a large body of land to a large body of water.
question
A tropical cyclone in the southern hemisphere rotates __________ and has a storm track turning ____________
answer
clockwise; south and southeast
question
A tropical cyclone will be weakened by
answer
when it makes land fall.
question
On weather maps, cold fronts are depicted by_____.
answer
Blue lines with blue triangles
question
A tropical cyclone will be strengthened by
answer
a path over warm water
question
Which phenomena involves the most equations in weather forecasting models?
answer
atmospheric motion
question
The dominant control in global sea surface temperature is
answer
the supply of solar insolation.
question
A Kelvin wave develops when
answer
westward moving winds weaken causing the mound of warm water in the western Pacific to move eastward.
question
Subtropical waters are typically more saline than equatorial waters because of
answer
high evaporation, low precipitation.
question
During the warm phase of ENSO, a belt of much warmer than normal water appears along the_____.
answer
equator in the eastern Pacific
question
In regard to ocean salinity, temperature, and density
answer
ice formation in polar zones increases salinity and density
question
During the warm phase of ENSO, warmest waters are found along the
answer
equator in the eastern Pacific, west of South America.
question
Sea Surface Temperatures (SST) are warmest
answer
at the subtropics because descending air promotes clear skies.
question
Warm oceanic pools form in areas of
answer
rising, unstable air where much latent heat is released.
question
Which gives rise to equatorial upwelling?
answer
Coriolis deflection causes warmer surface waters to deflect to the northwest causing deeper, cooler waters to replace the dispersing surface water.
question
In the Northern Hemisphere cold currents tend to flow from the ____________. In the Southern Hemisphere warm currents tend to flow from the ________________
answer
north; north
question
With height, wind speed in the atmosphere would _______________. With depth, the effect of wind on the water column would _________________.
answer
increase; decrease
