This air mass forms over warm oceans and is hot and humid
What is maritime tropical?
High-pressure systems usually bring this type of weather.
What is clear and sunny?
This front forms when a warm air mass moves over a cold air mass.
What is a warm front?
A large blue "H" on a weather map stands for this.
What is high pressure?
This type of pressure system is responsible for forming thunderstorms.
What is a low pressure system?
This air mass is cold and dry, forming over Canada and the Arctic
What is continental polar?
Low-pressure systems are associated with this type of weather
What is cloudy and stormy?
This type of front can bring thunderstorms when cold air forces warm air to rise quickly
What is a cold front?
A red line with semi-circles on a weather map represents this type of front.
What is a warm front?
The boundary between two air masses where storms often develop is called this.
What is a front?
This warm and dry air mass originates over deserts
What is continental tropical?
Winds in a low-pressure system move in this direction in the Northern Hemisphere
What is counterclockwise?
This front happens when two air masses push against each other but don’t move much
What is a stationary front?
Red and blue are used for this type of weather condition to indicate temperature
What are fronts?
When cold air meets warm air, the cold air sinks below the warmer air due to a difference of this property of air
What is density?
This air mass brings cool, humid conditions from the northern Pacific or Atlantic Ocean
What is maritime polar?
This weather pressure system causes air to move inward & upward
What is a low pressure system?
This front occurs when a cold front overtakes a warm front.
What is an occluded front?
On a weather map, a blue line with triangles represents this type of front.
What is a cold front?
The cold or warm air mass is always located in this position when examining a front line on a weather map
What is behind the air front line?
Which air mass is most responsible for hurricanes forming in the Atlantic Ocean?
What is maritime tropical?
High-pressure systems typically cause air to do this
What is sink?
Which front usually brings steady rain followed by warm, humid weather?
What is a warm front?
The position or orientation of the triangles and semi-cirlces on a weather map provides this type of information
What is the direction the front is moving?
Identifying the difference between a stationary front and an occluded front on a weather map is simple, as in a stationary front the semi-circles and triangles are pointing in this direction
What is opposite directions?
