Weather & Climate 2

Air pressure

• the force of air pressing down on a given area
• instrument that determines wind direction
• It is the horizontal movement of air from an area of high pressure to an area of low pressure
• condition of earth's atmosphere at a particular time and place (constantly changing)

Altitude

• distance above sea level
• the force of air pressing down on a given area
• instrument that determines wind direction
• It is the horizontal movement of air from an area of high pressure to an area of low pressure

Anemometer

• instrument used to measure wind speed
• distance above sea level
• the force of air pressing down on a given area
• instrument that determines wind direction

Atmosphere

• the layer of gases that surround a planet
• instrument used to measure wind speed
• distance above sea level
• the force of air pressing down on a given area

Barometer

• instrument used to measure changes in air pressure
• the layer of gases that surround a planet
• instrument used to measure wind speed
• distance above sea level

Cirrus

• wispy, feathery clouds made of ice crystals. They form high in the troposphere and don't usually produce precipitation
• instrument used to measure changes in air pressure
• the layer of gases that surround a planet
• instrument used to measure wind speed

Climate

• based on observations of weather that have been collected over many years (long term weather patterns)
• wispy, feathery clouds made of ice crystals. They form high in the troposphere and don't usually produce precipitation
• instrument used to measure changes in air pressure
• the layer of gases that surround a planet

Clouds

• tiny water or icy particles that are grouped together in the atmosphere when water vapor condenses
• based on observations of weather that have been collected over many years (long term weather patterns)
• wispy, feathery clouds made of ice crystals. They form high in the troposphere and don't usually produce precipitation
• instrument used to measure changes in air pressure

Cold Front

• A front in which a cold air mass pushes a warm air mass upward
• tiny water or icy particles that are grouped together in the atmosphere when water vapor condenses
• based on observations of weather that have been collected over many years (long term weather patterns)
• wispy, feathery clouds made of ice crystals. They form high in the troposphere and don't usually produce precipitation

Composition

• what something is made up of
• A front in which a cold air mass pushes a warm air mass upward
• tiny water or icy particles that are grouped together in the atmosphere when water vapor condenses
• based on observations of weather that have been collected over many years (long term weather patterns)
