4B Test: (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.

Front

How do jet streams affect weather?

Back

Jet streams can impact wind, precipitation, and temperature by carrying weather systems and influencing their movement.

Front

What are air masses?

Back

Air masses are large bodies of air that have uniform temperature and humidity characteristics, which can affect local weather when they move.

Front

What is a sea breeze?

Back

A sea breeze is the movement of air from the sea to the land during the day, caused by the differential heating of land and water.

Front

What type of weather is associated with low pressure systems?

Back

Low pressure systems are usually associated with stormy and unsettled weather.

Front

What is a land breeze?

Back

A land breeze is the movement of air from the land to the sea at night, caused by the cooling of land faster than water.

Front

What role do air masses play in weather?

Back

Air masses can bring different weather conditions depending on their source region, such as warm, cold, dry, or moist air.

Front

What happens when a jet stream shifts?

Back

When a jet stream shifts, it can lead to changes in local weather patterns as it carries different air masses and weather systems.

Front

What is the difference between high pressure and low pressure systems?

Back

High pressure systems are generally associated with clear skies and calm weather, while low pressure systems are linked to cloudy, stormy weather.

Front

How does temperature affect weather patterns?

Back

Temperature differences can create pressure differences, leading to wind and influencing weather systems.
