4B Test: (m) Global Patterns of Weather Maps

Front

What happens when a warm air mass passes over a cold air mass?

Back

As the warm air cools, clouds form and rain is likely to fall.

Front

What is the role of jet streams in weather?

Back

Jet streams can impact wind, precipitation, and temperature.

Front

How do jet streams influence local weather?

Back

Weather systems near jet streams are carried, causing local weather to change as new systems move in and prior systems move away.

Front

What is the primary source of most weather?

Back

Air masses are the primary source of most weather.

Front

What type of weather is associated with low pressure systems?

Back

Low pressure systems typically bring stormy, cloudy weather.

Front

Define 'air mass'.

Back

An air mass is a large body of air that has uniform temperature and humidity characteristics.

Front

What is a cold front?

Back

A cold front is the leading edge of a cooler mass of air, replacing a warmer mass.

Front

What is a warm front?

Back

A warm front is the leading edge of a warmer mass of air, replacing a cooler mass.

Front

What weather phenomena can occur due to the collision of air masses?

Back

The collision of air masses can lead to storms, precipitation, and changes in temperature.

Front

What is the significance of high pressure systems in weather?

Back

High pressure systems are generally associated with clear skies and stable weather.
