Air Masses and Weather Patterns 12/8/25

What are the two primary factors used to classify air masses?

• Moisture content and temperature

• Humidity and latitude

• Pressure and altitude

• Wind speed and direction

Which type of air mass is extremely cold and dry, originating from polar regions?

• Maritime tropical (mT)

• Continental Arctic (cA)

• Maritime polar (mP)

• Continental tropical (cT)

What is the role of the jet stream in the movement of air masses?

• It creates new air masses

• It alters the intensity and position of air masses

• It prevents air masses from acquiring new attributes

• It causes air masses to remain stationary

What type of weather is typically associated with maritime tropical (mT) air masses?

• Clear skies and cooler temperatures

• Cloudy and rainy conditions

• Severe weather events like thunderstorms and hurricanes

• Snow and freezing rain

What happens when a cold air mass undercuts a warm air mass at a weather front?

• The warm air sinks, causing clear skies

• The warm air rises, potentially leading to cloud formation and rainfall

• The cold air mass dissipates

• The boundary between air masses becomes stationary
