Stationary Front
What weather feature is located just north of "B" in Canada at the top of the chart of the
previous
question? - CORRECT ANSWER✔✔- High Pressure Center
What weather feature in question 1 is located at "C" and extends from Ohio to Texas? -
CORRECT ANSWER✔✔- Cold Front
What weather feature on the following surface chart is located at D extending through
Alabama? - CORRECT ANSWER✔✔- Squall Line
What is the weather feature located to the immediate northwest of "E" in Ohio in the previous
question? - CORRECT ANSWER✔✔- Low Pressure Center
What weather feature, extending from Ohio to New York, is located at "F" on the surface
chart of
questions 1 & 4? - CORRECT ANSWER✔✔- Warm Front
The following shows feature F from the previous question in more detail: - CORRECT
ANSWER✔✔- Between 20 and 35 F.
What approximate range of temperatures are to the south of feature F (from the front to
around
the south end of the dark line in Pennsylvania)? - CORRECT ANSWER✔✔- Between 50
and 65 F.
Generally what direction are the winds to the north of feature "F" near the extreme top of the
, black line? - CORRECT ANSWER✔✔- In the range from 360 to 090.
Generally what direction are the winds to the south of feature "F" near the bottom of the
black
line? - CORRECT ANSWER✔✔- In the range from 180 to 270
As you move from south to north following along the black line, how do the winds change in
terms of direction? - CORRECT ANSWER✔✔- They shift cyclonically from
southerly/southwesterly to easterly/northeasterly.
Generally, what are the range of dew point temperatures to the north of the frontal feature
"F"? - CORRECT ANSWER✔✔- 32 F and below.
Generally what are the dew point temperatures south of the frontal feature "F". - CORRECT
ANSWER✔✔- generally above 50 degrees F.
How is the moisture content of the air changing as you move from south to north across the
black line? Here we are interested in the actual moisture content, not how close the stations
are
to saturation (two different quantities). For actual moisture, examine the dew point value
itself.
For proximity to saturation you would examine how close the temperature is to the dew point
temperature. - CORRECT ANSWER✔✔- The moisture content decreases significantly as
you follow the line from south to north.
Look at the air temperatures and dew point temperatures to the north in Canada (region
around
A), in the eastern US (region around B, i.e. the warm sector), and in the Central Great Plains
regions (region around C). How would you describe the air mass in the eastern US (region
around B) in relation to the other two regions. - CORRECT ANSWER✔✔- The air in B
tends to be warmer with greater moisture content than both the air in region C and in region
A.
