• SC.5.E.7.3 Recognize how air temperature, barometric pressure, humidity, wind speed and direction, and precipitation determine the weather in a particular place and time.
• SC.5.E.7.7 Design a family preparedness plan for natural disasters and identify reasons for having such a plan.

Windy Weather

• Air is made of matter. It has mass and volume.
• Air pressure is the weight of the atmosphere on Earth’s surface.
• The sun does not heat all parts of Earth evenly. This causes changes in air pressure.

Windy Weather

• Wind is moving air.
• Differences in air pressure cause the air to move.
• Wind blows from areas of high pressure to areas of low pressure.
Local Winds
• Land heats up more quickly than water does during the day.
• A sea breeze forms during the day when warm air over land rises and cool air over water moves inland to replace it.

Local Winds
• Land loses heat faster than water at night.
• A land breeze forms when cool air over land moves out to sea to replace the warm air rising from the water.

• An air mass is a large body of air that has the same temperature and moisture properties throughout.
• An air mass that forms over warm land will be warm and dry.
• An air mass that forms over cold water will be cold and wet.

• The boundary where two different air masses meet is called a front.
• A cold front forms where a cold air mass moves under a warm air mass.
• A warm front forms where a warm air mass moves over a cold air mass.

• Meteorologists get data from weather tools located at weather stations.
• A weather station is a structure that has tools for measuring and recording weather data at a given location.
• Satellites and Doppler weather radar are also used to gather weather data.

When Disaster Strikes
Copyright © Houghton Mifflin Harcourt Publishing Company
• Tornadoes, hurricanes, and blizzards are types of severe weather.
• A tornado has a funnel shape and can form from violent thunderstorms.
• A hurricane is a strong low-pressure storm that forms over warm water.
