100
Air always moves from areas of ___ pressure to areas of ___ pressure.
high, low
100
What type of air mass would have the greatest effect on Alaska?
maritime polar
100
Which stage of a thunderstorms life is the most severe?
mature stage
200
What is the definition of weather?
atmospheric conditions, along with short-term changes, of a certain place at a certain time
200
What type of air mass has the greatest effect on Florida?
maritime tropical
200
What does a cold front bring to an area?
cool air, thunderstorms
200
What tool is air pressure measured with?
barometer
300
the pressure a column of air exerts on the air or surface below it?
air pressure
300
When updrafts within a thunderstorm begin to rotate, what might form?
tornado
300
This tool is attached to a ballon and gathers an upper-air report
radiosonde
300
What type of weather report is measured from the ground? What type of radar is used?
surface report, Doppler radar
400
Draw a diagram of a cold front. Include the direction of air pressures and precipitation
see diagram from textbook p162
400
The amount of water vapor in the air relative to the air temperature?
relative humidity
400
The temperature when air is fully saturated with water vapor?
Dew point
400
Cooler air can hold (more or less) humidity then warmer air? Why?
Less, warmer air is less dense then cooler air and can hold more water vapor
500
How does the water cycle pertain to weather?
Without evaporation, you would not have water vapor in the air to condense and form clouds. Without clouds, you would not have precipitation, precipitation is a weather variable.

What is the difference between a stationary and an occluded front?
Stationary is a cold front and a warm front pushing on one another and not moving. An occluded front is when a warm front is moving through an area but another cold front, being denser, begins to push it upwards, sandwiching the warm air between two cold fronts.

What is the difference between isobars and isotherms.
isobar- area of same pressure
isotherm- area of same temperature
