This air mass forms over the ocean near the equator...
What is maritime tropical (mT)?
200
This is when a warm air mass slowly moves over a cold, denser air mass, gradually replacing it. Forms drizzly rain followed by clear and sunny weather.
What is a warm front?
200
This technology is used to located precipitation, calculate its motion, and estimate its type (rain, snow, ice, etc)
What is a weather radar (or doppler radar)?

What is D?
300
This is a dry, warm air mass.
What is continental tropical (cT)?
300
This is when a cold air mass pushes up a less-dense warm air mass, causing severe weather like 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 is choice 4?

What is C?
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 force to move the other. Brings many days of cloudy, wet weather.
What is a stationary front?

What is an anemometer?
400
This is the symbol for an occluded front.
What is choice 3?
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 than cold air.
500

What is continental polar (cP)?
500
This is when a warm air mass is trapped between two colder air masses. The coldest air mass pushes out the warm and less dense one and causes large amounts of snow or rain and cold temperatures.
