Air Masses
This is a large body of air where temperature and moisture content are similar throughout.
What is an air mass?
The area in which two or more types of masses meet is called a __________.
What is a front?
This is a weather instrument used to measure temperature.
What is a thermometer?
This is the symbol for a warm front?
What are red semicircles facing the direction the front is moving?
This is the energy of motion.
What is kinetic energy?
This is a wet, warm air mass.
What is maritime tropical (mT)?
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?
This is how weather stations and apps visually represent weather conditions overlaid on a map.
What is a radar?
This is the symbol for a cold front.
What are blue triangles facing the direction the front is moving?
This is stored energy.
What is potential energy?
This is a dry, warm air mass.
What is continental tropical (cT)?
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?
This is a weather instrument used to measure air pressure.
What is a barometer?
This is the symbol for a stationary front.
What are alternating red semicircles and blue triangles facing opposite directions?
This is the effect the rotation of the earth causes on winds which causes them to appear to curve.
What is the Coriolis Effect?
This is a wet, cold air mass.
What is maritime polar (mP)?
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?
Which direction (rising or falling) on a barometer usually indicates wet weather arriving?
What is a falling?
This is the symbol for an occluded front.
What are alternating red semicircles and blue triangles facing the same direction?
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.
This is a dry, cold air mass.
What is continental polar (cP)?
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?
This is the weather instrument used to measure wind speed.
What is an anemometer?
What is WW1 and weather forecasters imagining opposing air masses meeting as if on a battlefield?
This is the process of warm air rising and cold air sinking.
What is convection?
