Our Atmosphere
The layer of the atmosphere that contains ozone
This large body of air has the same characteristics throughout it
What is an air mass?
A comparison of the actual amount of moisture in the air to the greatest amount possible at that temperature and pressure
What is relative humidity?
What is an anemometer?
cumulonimbus clouds
low pressure
cold front meets warm front
What is a thunderstorm (or tornado)?
The layer of the atmosphere that has the most water vapor and weather activity
What is the troposphere?
When a cold air mass meets up with a warm air mass, the warm air moves in this direction
What is upwards?
Rain, snow, hail, sleet
What is precipitation?
Instrument used to measure temperature
What is a thermometer?
Stationary front
Temperature 50 degrees
What is rain?
The layer of the atmosphere where auroras occur
What is the thermosphere?
This kind of front is formed when a warm air mass is pushed up between two cold air masses
What is an occluded front?
What are the westerlies?
Instrument used to measure air pressure
What is a barometer?
Cirrus clouds
Warm front
High pressure
What is a clear (mild) day?
These two gases are most abundant in the atmosphere
What are nitrogen and oxygen?
The front that forms when warm and cold air masses collide and stop moving
What is a stationary front?
What is a meteorologist?
Found in space, these instruments allow meteorologists to see storms before they happen.
What are satellites?
Low pressure
Very High Winds
Tropical location
Heavy rain
What is a hurricane?
The layer of the atmosphere where jets fly to avoid storms
What is the stratosphere?
This type of weather typically occurs at a cold front
What is precipitation or storms?
The type of cloud that appears soft, like cotton, and usually brings fair weather or light precipitation
What are cumulus clouds?
This instrument is used to measure the wind direction
What is a weather vane?
Layer of cold air above warm air
Low pressure
Cumulonimbus clouds
Very high winds with rotation
What is a tornado?
