Measuring Up
The is the total amount of moisture that the air can hold.
Absolute humidity
The measure of amount of water vapor in the air at this time is called:
relative humidity
This type of air holds more water vapor.
What is warm air and this is why areas near the equator are warmer.
This type of front is made up of cold and warm air masses where neither one is strong enough to push the other out of the way.
stationary front
What information can you get from a weather map?
location of fronts, high low pressure areas, precipitation amounts
This tool measures wind speed
anemometer
This type of air is more dense, therefore, will sink.
What is cold air.
This is how wind is related to air temperature and air pressure
differences in air pressure are often caused by differences in air temperature
Which type of front has fast moving warm air overtaking slow moving cold air and the warm air moves over the cold and generally brings warmer nice weather?
warm front
What causes changes in weather?
air masses moving and meeting
This is what happens to the liquid inside of a thermometer when it warms up.
it expands which will make it rise up the tube
Average weather conditions in a given place over longer periods of time are referred to as
climate
Which of the following air masses has warm, wet air.
a) Maritime tropical
b) Continental tropical
c) Maritime polar
d) Continental polar
What is Maritime tropical (maritime means water and tropical means warm near the equator).
What type of front typically brings thunderstorms?
Cold front

meteorologist
Air pressure will do this as you increase in altitude and this is the reason why.
It will decrease. Most pressure is the troposphere because 80% of gases are in this sphere.
This is how climiate differs from weather.
Climate is long term and weather is daily
This is the weather that can be expected after an occluded front comes through.
Heavy rain
What type of weather is associated with high pressure?
fair weather
What is used on a weather map to indicate a low pressure system (this is the symbol and color)?
L (blue)
This is the average amount of energy of motion of each particle of a substance.
What is temperature?
What is the primary source of energy that drives all weather events?
sun
Which layer of the atmosphere is where all weather takes place?
troposphere
Bands of high speed winds that are hundreds of kilometers wide but only a few kilometers deep are known as _________________.
Jet streams
Why does the equator have about the same temperature year round?
The sun's rays strike the equator at about the same angle all year
