Weather Instruments
Measures air temperature
What is a thermometer?
The boundary where two unlike air masses meet.
What is a front?
A local wind that during the day blows from sea to land.
What is a sea breeze?
An air mass that can be described as cold and moist.
What is maritime polar?
A huge body of air that has similar temperature, humidity, and air pressure at any given height.
What is an air mass?
Measures wind direction
What is a wind vane?
Swirling center of low pressure air often associated with storms and precipitation.
What is a cyclone?
A local wind that blows at night from land to sea.
What is a land breeze?
An air mass that can be described as warm and dry.
What is continental tropical?
A cold air mass takes over a warm air mass, bringing strong thunderstorms and heavy rains.
What is a cold front?
Measures wind speed
What is an anemometer?
Sudden, violent floods that occur shortly after a storm.
What is a flash flood?
Winds that blow steadily from a specific location over long distances.
What are global winds?
What is maritime tropical?
Occurs when a warm air mass takes over a cold air mass. Brings a few days of gentle rain.
What is a warm front?
Measures air pressure
What is a barometer?
A high pressure center of dry air (usually dry and clear)
What is an anticyclone?
The effect of Earth’s rotation on the direction of winds and currents.
What is the Coriolis Effect?
An air mass that is cool and dry.
What is continental polar?
A stalled front that may bring many days of clouds and precipitation.
What is a stationary front?
Measures relative humidity
What is a hygrometer/psychrometer?
A long period of scarce rainfall or dry weather.
What is a drought?
Blow from the west to east away from horse latitudes. Between 30° and 60° N and S.
What are the Prevailing Westerlies?
An air mass that forms over Arizona and New Mexico.
What is continental tropical?
A cold air mass catches up to a warm front, lifting the warm air mass off the ground.
What is an occluded front?
