4B Test Corrections: (h) Global Patterns of Weather Maps

Front

What is a jet stream?

Back

A jet stream is a fast-flowing air current found in the atmosphere, typically at high altitudes, that influences weather patterns by moving weather systems.

Front

How do jet streams influence local weather?

Back

Jet streams carry weather systems, causing local weather to change as new systems move in and prior systems move away.

Front

What is the general direction of air mass movement over the continental United States?

Back

Air masses generally move from west to east over the continental United States.

Front

What is a maritime air mass?

Back

A maritime air mass is a type of air mass that is humid and forms over water.

Front

What is a continental air mass?

Back

A continental air mass is a type of air mass that forms over land and is typically dry.

Front

What type of weather is associated with a cold front?

Back

Cold fronts are associated with sudden temperature drops, thunderstorms, and precipitation.

Front

What is the difference between maritime and continental air masses?

Back

Maritime air masses are humid and form over water, while continental air masses are dry and form over land.

Front

What role does Earth's rotation play in global weather patterns?

Back

Earth's rotation causes the Coriolis effect, which influences wind direction and the movement of weather systems.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as air masses, due to Earth's rotation, causing them to turn to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

Front

What is a warm front?

Back

A warm front is a boundary where a warm air mass replaces a cold air mass, often leading to gradual temperature increases and prolonged precipitation.
