Approaching Weather
100
This is a measurement of the energy in the atmospheres gas molecules (Nitrogen, Oxygen, and the rest)
What is temperature?
100
it rises because of this
What is a warm air mass?
100
What happens to water in the air when clouds form
What is condensation of water vapor?
100
These clouds are big, fluffy-looking aCUMULations of water vapor, often against a blue sky
What are Cumulus Clouds?
100
What to expect when high pressure is coming our way
What is Sunny skies?
200
This is a measure of the weight of the air on the Earth's surface
What is Atmospheric pressure?
200
air rushes into these at ground level in a counter-clockwise direction
What is a Low Pressure center?
200
This precipitation starts as ice crystals in the clouds and stays completely frozen all the way down to the ground
What is Snow?
200
These feathery, very-high clouds are made of ice crystals
What are Cirrus Clouds?
200
What happens when a cold, high-pressure air mass coming from the west slams into a warm, moist air mass
What are Thunderstorms?
300
This is a measure of how fast the air is moving past us
What is Wind Speed?
300
These air masses are associated with sunshine-y weather
What is High Pressure?
300
This precipitation starts as ice crystals, partially melts in warmer air on the way down, and then freezes again before it hits the ground
What is sleet?
300
These clouds form a continuous, low altitude blanket, giving us grey skies
What are Stratus Clouds?
300
This type of front could give us cloudy, wet weather for several days in a row
What is a Stationary Front?
400
The unit of measurement used to measure the weight of the air on the surface of the Earth
What is Millibars?
400
The warmer it is, the more of this it can hold
What is Water Vapor?
400
This precipitation starts as ice crystals, completely melts in warmer air on the way down, and then freezes when it hits the ground
What is Freezing Rain?
400
These are the clouds of developing thunderstorms that keep getting taller and taller in the sky
What are Cumulonimbus Clouds?
400
Weather in North America generally moves from this direction to that direction
What is West to East?
500
The temperature at which the water vapor condenses out of the air
What is the Dewpoint?
500
How air temperature changes as it rises?
What is cooling?
500
The word used to described very tiny water droplets that can remain liquid down to -40 Celsius
What is "Super-cooled"?
500
This is one of the blanket-type clouds that forms at the Earth's surface
What is Fog?
500
What this symbol means
What is a cold front?
