A(n)________ is a homogenous volume of air defined based on its temperature, and moisture characteristics.
cyclone
air mass
front
parcel
Which of the following is false regarding air masses?
An air mass initially reflects the characteristics of its source region.
They are homogenous in terms of temperature and humidity.
Air masses interact to create weather patterns.
Air masses maintain their original characteristics as they migrate from their source regions.
Which of the following pressure systems reside within the source region for mP air masses?
Bermuda high and Pacific high
Aleutian low and Icelandic low
Bermuda high and Icelandic low
Aleutian low and Pacific high
The maritime tropical Pacific (mT) and maritime tropical Gulf and Atlantic (mT) air masses are
different from one another because the Pacific air mass usually has lower specific humidity than the Gulf/Atlantic air mass.
both usually extremely unstable.
both less active during summer months.
similar in that neither occur during the Northern Hemisphere winter.
Which of the following would not result in the modification of the air mass?
A mT air mass moving across Texas
A cP air mass moving across the Great Lakes
A cT air mass moving across the Gulf of Mexico
A cP air mass remaining stationary over central Canada
Air flowing from different directions to an area of low pressure, coming together, and being displaced upward is an example of ________ lifting.
convergent
convectional
orographic
frontal
Air rising as a result of being stimulated by local surface heating is an example of ________ lifting.
convergent
convectional
orographic
frontal
Air rising forcibly lifted upslope when it meets a topographic barrier such as a mountain is an example of ________ lifting.
convergent
convectional
orographic
frontal
The term "orographic" refers to
convection stimulated principally by local heating.
lifting along the edges of conflicting air masses.
air mass modification and the formation of secondary air masses.
forced uplift due to the presence of a physical barrier.
The wetter, intercepting slope of a mountain is termed the ________ slope, whereas the drier, downwind slope is termed the ________ slope.
left side; right side
west side; east side
windward; leeward
leeward; windward
The term "rain shadow" refers to
periods of time during which there is a lack of rainfall.
dry regions on the leeward side of mountain ranges.
windward slopes of mountains.
wet areas on the downwind sides of mountains.
Air displacement at a zone of discontinuity between two air masses of different temperature, pressure, humidity, wind speed and direction, and cloud development is an example of ________ lifting.
convergent
convectional
orographic
frontal
Which of the following is incorrectly matched?
abruptly lifted warmer air - cold front
drizzly precipitation - warm front
cold front - clear cold air and high clouds as the front approaches

are rarely associated with hurricanes.
are associated with mesocyclones.
do not occur anywhere else in the world outside of the United States.
are called funnel clouds after they come in contact with the ground.
Tropical cyclones
are produced by the conflict between air masses and frontal activity.
originate entirely within tropical air masses.
usually form poleward of 23.5° latitude in either hemisphere.
