Weather Patterns

Chapter 3 Lesson 2

Lesson Stats

• SC.6.E.7.3 Describe how global weather patterns such as the jet stream and ocean currents influence local weather in measurable terms such as temperature, air pressure, wind direction and speed, and humidity and precipitation

• GOAL: Differentiate between the weather fronts and the weather associated with them

• ESSENTIAL QUESTION: What effect does each front have on local weather conditions?

Multiple Choice

Wind moves from areas of .............. to areas of ...............?

• high pressure to low pressure

• low pressure to high pressure

Multiple Choice

Weather is a ............. condition of a certain place during a certain time.

• long term

• short term

• water cycle

• none of the above

Pressure Systems

• High Pressure Systems: high pressure in the center (dry weather, clear skies)

• Low Pressure Systems: low pressure in the center (clouds and precipitation).

Air Masses

• large bodies of air that have the same temperature, humidity, and pressure.

• Formed when high pressure systems lingers over an area.

Multiple Choice

What happens when a high pressure system comes in contact with Earth?

• it gets hot

• it gets cold

• shows the temperature and humidity of the area below it

• a hurricane forms

Multiple Choice

How are air masses formed?

• when low pressure systems linger over an area

• when the air is cold

• when the air is hot

• when high pressure systems linger over an area

Types of Air Masses

• Maritime Polar (cold and humid)

• Continental Polar (cold winters, cool summers)

• Arctic (bitterly cold, dry air)

Types of Air Masses

• Maritime Tropical (hot and humid summers, snowfall in winter)

• Continental Tropical (clear skies, high temperatures

Multiple Choice

What type of air masses forms over oceans?

• arctic

• continental

• maritime

• tropical

Multiple Select

What type of air masses form over land?

• arctic

• maritime

• continental

• tropical

Fronts

a boundary between two air masses

Warm Front

Forms when warm air moves toward cool air (steady precipitation)

Cold Front

cold air pushes underneath warm air (showers and thunderstorms)

Multiple Choice

If it is drizzling rain outside, what type of front has occured?

• Warm Front

• Cold Front

• Maritime

• Polar

Multiple Choice

Uh Oh! Severe Thunderstorm is happening. What type of front has occurred?

• Cold Front

• Warm Front

• Tropical

• Continental
