Fronts
This is a boundary between two air masses
What is a front?
These air masses originate over water
What are maritime air masses?
This is caused by the weight of the air above an area
What is air pressure?
This measures temperature in Fahrenheit and Celsius
What is a thermometer?
The H representing high pressure on a weather map is to show air that is cooling so it is this color
What is blue?
A warm air mass glides over the cooler air mass producing light drizzle or snow.
What are warm fronts?
This air mass is warm and humid.
What is maritime tropical?
This type of pressure causes clouds and rain or storms.
What is Low Pressure?
This helps determine direction when reading weather maps.
What is a Compass Rose?
This is the color and symbol for Low Pressure.
What is L (red).
Cold air rushes under the warm air forcing it to rise.
What are cold fronts?
This air mass is formed over Canada.
What is Continental Polar?
This makes sunny clear skies with calm winds that spiral clockwise
What are high pressure systems?
Air pressure is measured with this
What is the barometer?
This word means- less to more
What is increasing?
Showers and thunderstorms form around the leading edges of these fronts
What are cold fronts?
This is a large body of air with relatively similar temperature and humidity
What are air masses?
This is how Low Pressure air moves.
What is Counter-clockwise?
This measures wind speed in mph
What is the anemometer?
This word means--- going from more to less.
What is Decreasing?
These cause light rain over several days. Warm and cold air masses face each other but do not move.
What are stationary fronts?
These air mass is warm and dry.
What is Continental Tropical?
These are lines connecting points of equal atmospheric pressure
What are isobars?
This carries instruments to high altitudes
What is a weather balloon?
This means conditions of the atmosphere at a given time.
