100

This is a large body of air where temperature and moisture content are similar throughout.

What is an air mass?

100

The area in which two or more types of masses meet is called a __________.

What is a front?

100

This is a weather instrument used to measure temperature.

What is a thermometer?

100

This is the symbol for a warm front?

What are red semicircles facing the direction the front is moving?

100

This is the energy of motion.

What is kinetic energy?

200

This is a wet, warm air mass.

What is maritime tropical (mT)?

200

This is when a warm air mass moves over colder, denser air gradually replacing it. Forms drizzly rain followed by clear and warm weather.

What is a warm front?

200

This is how weather stations and apps visually represent weather conditions overlaid on a map.

What is a radar?

200

This is the symbol for a cold front.

What are blue triangles facing the direction the front is moving?

200

This is stored energy.

What is potential energy?

300

This is a dry, warm air mass.

What is continental tropical (cT)?

300

This is when a cold air mass moves under a warm air mass forcing the less dense warm air upwards and causing thunderstorms, heavy rain, and snow.

What is a cold front?

300

This is a weather instrument used to measure air pressure.

What is a barometer?

300

This is the symbol for a stationary front.

What are alternating red semicircles and blue triangles facing opposite directions?

300

This is the effect the rotation of the earth causes on winds which causes them to appear to curve.

What is the Coriolis Effect?

400

This is a wet, cold air mass.

What is maritime polar (mP)?

400

This is when a cold air mass meets a warm air mass and neither has enough energy to lift the warm air mass over a cold air mass. Brings many days of cloudy, wet weather.

What is a stationary front?

400

Which direction (rising or falling) on a barometer usually indicates wet weather arriving?

What is a falling?

400

This is the symbol for an occluded front.

What are alternating red semicircles and blue triangles facing the same direction?

400

This is what causes warm air to rise and cold air to sink.

What is the difference in densities, warm air is less dense that cold air.

500

This is a dry, cold air mass.

What is continental polar (cP)?

500

This is when a warm air mass is trapped between two colder air masses. The coldest air mass moves under the other two air masses and causes large amounts of snow or rain and cool temperatures.

What is an occluded front?

500

This is the weather instrument used to measure wind speed.

What is an anemometer?

500
This is where the term front originates.

What is WW1 and weather forecasters imagining opposing air masses meeting as if on a battlefield?

500

This is the process of warm air rising and cold air sinking.

What is convection?
