1. A capital "L" on a weather map indicates a region of low air pressure, which often brings cloudy or stormy weather.

True

False

If low pressure occurs where air rises and cools to form clouds, then the "L" symbol correctly identifies areas likely to experience precipitation.

About This Quiz

Decoding The Sky: The Ultimate Weather Maps Quiz - Quiz

Decoding the secret language of the forecast. To a meteorologist, a map is filled with symbols that tell a story of pressure, wind, and temperature. This weather maps quiz puts the ability to translate these complex visual blueprints to the test.

2. What first name or nickname would you like us to use?

You may optionally provide this to label your report, leaderboard, or certificate.

2. What do the blue triangles on a weather map line represent?

Warm Front

Cold Front

Stationary Front

Occluded Front

High Pressure

If blue is the color used for cold temperatures and triangles represent the direction of a moving air mass, then this symbol indicates a cold front.

Explanation

If blue is the color used for cold temperatures and triangles represent the direction of a moving air mass, then this symbol indicates a cold front.

Submit

3. A weather map with many close isobars over the ocean suggests that sailors should expect calm seas.

True

False

If close isobars indicate high wind speeds, and high winds create large waves, then the weather conditions will be rough rather than calm.

Explanation

If close isobars indicate high wind speeds, and high winds create large waves, then the weather conditions will be rough rather than calm.

Submit

4. What does a red line with red semicircles represent on a weather map?

Cold Front

Stationary Front

Warm Front

Occluded Front

Jet Stream

If red is the color for heat and semicircles represent the forward edge of moving warm air, then this symbol signifies a warm front.

Explanation

If red is the color for heat and semicircles represent the forward edge of moving warm air, then this symbol signifies a warm front.

Submit

5. The symbol consisting of purple triangles and semicircles on the same side of a line represents an _____ front.

If a cold front overtakes a warm front and lifts it off the ground, then the combined purple symbol represents this specific occluded state.

Explanation

If a cold front overtakes a warm front and lifts it off the ground, then the combined purple symbol represents this specific occluded state.

Submit

6. If isobars are spaced very close together on a map, what does this indicate about the wind?

Light winds

No wind

High wind speeds

Changing wind direction

Increasing humidity

If isobars show pressure changes over distance, and a steep change (lines close together) creates a strong pressure gradient force, then the wind will blow faster.

Explanation

If isobars show pressure changes over distance, and a steep change (lines close together) creates a strong pressure gradient force, then the wind will blow faster.

Submit

7. What does the dew point temperature on a station model tell us?

How hot the air is

The pressure of the air

The temperature at which water vapor condenses

The speed of the wind

The height of the clouds

If the dew point is the saturation temperature, then it indicates how much moisture is in the air and when dew or fog might form.

Explanation

If the dew point is the saturation temperature, then it indicates how much moisture is in the air and when dew or fog might form.

Submit

8. Which symbol represents a stationary front?

Blue triangles

Red semicircles

Purple triangles and semicircles

Alternating blue triangles and red semicircles on opposite sides

Green dashed lines

If two air masses are pushing against each other but neither is moving, then the symbols for both must appear on opposite sides of the boundary line.

Explanation

If two air masses are pushing against each other but neither is moving, then the symbols for both must appear on opposite sides of the boundary line.

Submit

9. If you see a symbol showing a blue line with triangles pointing South, which way is the cold air moving?

North

East

South

West

It is not moving

If the triangles on a front symbol act as directional arrows, then the air mass is moving in the direction those triangles are pointing.

Explanation

If the triangles on a front symbol act as directional arrows, then the air mass is moving in the direction those triangles are pointing.

Submit

10. On a weather map, a line with purple triangles and semicircles is called an _____ front.

If a faster cold front catches a slower warm front, then the resulting boundary is colored purple and called an occluded front.

Explanation

If a faster cold front catches a slower warm front, then the resulting boundary is colored purple and called an occluded front.

Submit

11. How is cloud cover represented on a weather station model?

A number in the center

A circle that is shaded

A series of dots

A letter code

A small cloud icon

If the central circle of a station model represents the sky, then the amount of shading inside that circle indicates the percentage of the sky covered by clouds.

Explanation

If the central circle of a station model represents the sky, then the amount of shading inside that circle indicates the percentage of the sky covered by clouds.

Submit

12. In a station model, the "feathers" or "barbs" on the wind staff indicate the wind speed.

True

False

If longer lines represent 10 knots and shorter lines represent 5 knots, then these marks effectively communicate the recorded wind speed.

Explanation

If longer lines represent 10 knots and shorter lines represent 5 knots, then these marks effectively communicate the recorded wind speed.

Submit

13. A capital "H" on a weather map usually signifies what kind of weather?

Hurricanes

Heavy Rain

Clear, fair weather

High humidity

Hailstorms

If high pressure causes air to sink and prevents cloud formation, then the area marked with "H" will typically have clear and dry skies.

Explanation

If high pressure causes air to sink and prevents cloud formation, then the area marked with "H" will typically have clear and dry skies.

Submit

14. In which direction does air generally move in a High Pressure system in the Northern Hemisphere?

Clockwise and Outward

Counter-clockwise and Inward

Straight North

Upward into the clouds

Only in circles

If the Coriolis effect acts on sinking air pushing away from a high-pressure center, then the air must circulate clockwise and move outward.

Explanation

If the Coriolis effect acts on sinking air pushing away from a high-pressure center, then the air must circulate clockwise and move outward.

Submit

15. On a weather map, _____ are used to show the boundary between two different air masses.

If different bodies of air do not mix easily, then the line representing the zone where they meet is called a front.

Explanation

If different bodies of air do not mix easily, then the line representing the zone where they meet is called a front.

Submit

16. What do "isotherms" connect on a weather map?

Points of equal pressure

Points of equal temperature

Points of equal elevation

Points of equal wind direction

Points of equal cloud cover

If "iso-" means equal and "therm" refers to thermal energy, then these lines connect geographic locations experiencing the same temperature.

Explanation

If "iso-" means equal and "therm" refers to thermal energy, then these lines connect geographic locations experiencing the same temperature.

Submit

17. Which of the following can be determined by looking at a weather station model?

Wind speed

Dew point

Current temperature

Name of the city

Air pressure

If a station model is a shorthand for local data, then it includes temperature, pressure, dew point, and wind, but it does not typically list the city name.

Explanation

If a station model is a shorthand for local data, then it includes temperature, pressure, dew point, and wind, but it does not typically list the city name.
