Air Mass Interactions

Which statement below describes an occluded front?

• Forms when warm and cold air meet and neither air mass has the force to move the other

• Forms when a cold air mass pushes under a warm air mass, forcing the warm air to rise

• Forms when a warm air mass gets caught between two cold air masses

• Forms when a moist, warm air mass slides up and over a cold air mass

What type of weather can typically be found at a stationary front?

• cool, fair weather

• gentle rain or light snow, followed by warmer, milder weather

• strong winds and heavy precipitation

• strong winds and heavy precipitation

What weather will result when a cold air mass moves into a warm air mass?

• gentle rain or light snow, followed by warmer, milder weather

• cool, fair weather

• many days of clouds and precipitation

• strong winds and heavy precipitation

What weather will result when a warm air mass moves into a cold air mass?

• gentle rain or light snow, followed by warmer, milder weather

• cool, fair weather

• many days of clouds and precipitation

• strong winds and heavy precipitation

What is responsible for driving all weather patterns on Earth?

• mountains

• the Sun

• the Moon

• oceans

A high-pressure system (H) is moving to the southeast as shown on the weather map. Cold air is usually found north and west of a high-pressure system. Warm air is to the south and east of the front. Continental air is drier while oceanic air has more moisture.

Based on this information, what is the BEST prediction for weather on the day after the system passes the point marked X?

• wet air with cooler temperatures

• wet air with warmer temperatures

• drier air with warmer temperatures

• drier air with cooler temperatures

The map of North America shows the position of the polar front jet stream on January 7, 2014, and the location of Atlanta, Georgia.

Which type of air mass was most likely located over Atlanta, Georgia?

• mT

• cP

• mP

• cT

Which of the following is the most likely cause of the humid conditions in coastal areas?

• runoff from inland mountains

• flooding from rivers and streams

• groundwater bubbling to the surface

• evaporation from the surface of the ocean

What MOST likely happens when a cold air mass comes into contact with a warm, moist air mass?

• Cold air is pushed to high altitudes.

• Warm air is pushed to ground level.

• Rain or snow begins to fall.

• The sky becomes clear.

The map of North America shows the source region of an air mass forming mostly over Mexico.

This air mass originating over Mexico is classified as

• continental polar

• maritime polar

• continental tropical

• maritime tropical
