There are at least 2 ways to practice this quiz. One way is to check your answer by clicking the "Check answer" button. This will give you immediate feedback regarding specific questions. The other option is to simply answer all the questions as a test and "Flip the switch" or "Press the button" (grade the test) after the last question to receive a test score. You can then check each question individually to see which questions were missed. If you have any problems or suspect an error, feel free to contact me anytime.

Thank you and good luck.

1. Constant Pressure Analysis Charts contain contours, isotherms and some contain isotachs. The contours depict

ridges, lows, troughs, and highs aloft.
highs, lows, troughs, and ridges on the surface.
highs, lows, troughs, and ridges corrected to MSL.

2. (Refer to 300mb chart.) What is the height of the 300-millibar level at the low pressure center in Canada?

9,120 meters MSL.
18,000 meters MSL.
11,850 meters MSL.

3. (Refer to the 200mb, 300mb, and 500mb charts.) Interpret the path of the jetstream.

Southern California, Nevada, Utah, Nebraska/Kansas, and then southeastward.
Oregon, Idaho, Wyoming, Nebraska, Iowa, and across the Great Lakes.
The Alaska area, across Canada to Montana, North Dakota, then across the Great Lakes area.

4. (Refer to the 500mb chart.) What type weather system is approaching the California Coast from the west?

LOW.
HIGH.
Cold front.

5. (Refer to the 200mb, 300mb, and 500mb charts.) What type weather is inferred by the almost vertical extent of the LOW in Canada?

A rapid-moving system with little chance of developing cloudiness, precipitation, and adverse flying conditions.
A slow-moving storm which may cause extensive and persistent cloudiness, precipitation, and generally adverse flying weather.
A rapid-moving storm, leaning to west with altitude, which encourages line squalls ahead of the system with a potential of severe weather.

6. (Refer to the 200mb, 300mb, and 500mb charts.) What is the approximate temperature for a flight from southern California to central Kansas at FL 350?

-16°C.
-39°C.
-41°C.

7. (Refer to the 200mb, 300mb, and 500mb charts.) Determine the approximate wind direction and velocity at FL 240 over the station in central Oklahoma.

280° at 10 knots.
320° at 10 knots.
330° at 13 knots.

8. (Refer to the 200mb, 300mb, and 500mb charts.) What is the relative moisture content of the air mass approaching the California coast?

Dry.
Moist enough for condensation.
Very wet with high potential for clouds and precipitation.

9. The horizontal wind shear, critical for turbulence (moderate or greater) per 150 miles is

18 knots or less.
greater than 18 knots.
not a factor, only vertical shear is a factor.

10. On the constant pressure analysis chart, satellite and aircraft observations are used in the analysis, over areas of sparse data. A satellite observation is plotted using

a station circle at the cloud top location.
a square at the cloud top location.
a star at the cloud top location.

11. On the constant pressure analysis chart, aircraft and satellite observations are used in the analysis, over areas of sparse data. An aircraft observation is plotted using

a station circle at the aircraft location.
a square at the aircraft location.
a star at the aircraft location.
