|
| 1.) |
The source region for an air mass is
likely to be _____________________. |
|
|
|
a mountainous region with high relief |
|
|
|
in the path of the westerlies in the middle latitudes |
|
|
|
a large, fairly uniform region |
|
|
|
over one of the Great Lakes |
|
|
|
just about anywhere |
|
| 2.) |
A cP (Continental Polar) air mass |
|
|
|
would most likely be cold and humid |
|
|
|
would be likely to form over the Rocky Mountains |
|
|
|
would develop in a cold, very rainy region |
|
|
|
would most likely be cold and dry |
|
|
|
would not be able to move as far south as the U.S. |
|
| 3.) |
An air mass forming in the Gulf of
Mexico
|
|
|
|
would be classified as a cT air mass |
|
|
|
would most likely be warm and dry |
|
|
|
would be a Maritime Tropical air mass |
|
|
|
would bring hot, dry weather to the southern part of the US |
|
|
|
would be cold and stable |
|
| 4.) |
A Maritime Polar air mass forming in
the North Atlantic
|
|
|
|
would be likely to bring cool, wet weather to Europe |
|
|
|
would be the most common and important source of rain and snow for the
east coast of the US |
|
|
|
would be cold and dry |
|
|
|
could never affect the east coast of the US |
|
|
|
would be an mT air mass |
|
| 5.) |
A Continental Tropical (cT) air mass
in North America |
|
|
|
would be hot and very humid |
|
|
|
would most likely form over the deserts in northern Mexico and the
southwestern US |
|
|
|
would usually bring intense precipitation to the southeastern US |
|
|
|
would be cold and dry |
|
|
|
could not develop, because there is no suitable source region |
|
| 6.) |
What is most likely to occur when a
mass of cold air moves into a region occupied by warmer air? |
|
|
|
A warm front will form, and there will be intense
precipitation. |
|
|
|
The air masses will mix rapidly, forming an air mass of intermediate
temperature. |
|
|
|
The boundary between the two air masses will be a zone of intense high
pressure. |
|
|
|
A cold front will form, as warm air is forced upward. |
|
|
|
All of the above. |
|
| 7.) |
A front that is characterized by
stratus clouds, and gentle precipitation for a long time is a(n) ____________ front. |
|
|
|
cold |
|
|
|
stationary |
|
|
|
warm |
|
|
|
occluded |
|
|
|
none of the above |
|
| 8.) |
A front is depicted on a weather map
by a line with triangles pointing in the direction the front is moving. This is a (n)
__________ front. |
|
|
|
stationary |
|
|
|
warm |
|
|
|
occluded |
|
|
|
maritime Tropical |
|
|
|
cold |
|
| 9.) |
Which of the following is least
likely to occur as a cold front passes? |
|
|
|
a decrease in air pressure |
|
|
|
intense precipitation from cumulunimbus clouds |
|
|
|
a shift in wind direction |
|
|
|
a drop in temperature |
|
|
|
steady precipitation that lasts for an extended time and covers a wide
region |
|
| 10.) |
After a cold front has passed, we
would expect |
|
|
|
cold temperatures and rain that lasts several days |
|
|
|
cool, humid conditions, and strong winds |
|
|
|
cold temperatures and clear skies |
|
|
|
low pressure over a wide region |
|
|
|
warm temperatures and clear skies |
