What is a front?
boundary separating bands of thunderstorms and severe weather
100
What are jet streams.
Fast flowing air currents

What does a weather map do?
A weather map and its symbols gather a lot of weather information quickly and without using a lot of words. Just as equations are the language of mathematics, weather symbols are the language of weather.

What are the 2 characteristics air masses are named after?
Humidity and temperature
100
When does a weather pattern occur?
A weather pattern occurs when the weather stays the same for days or weeks at a time.
200
Where does a warm front form?
Warm fronts often form on the east side of low-pressure systems where warmer air from the south is pushed north.

What are the different types of air masses
Continental polar marine, time polar, continental tropical marine, time tropical

What do fronts and air masses have in common
the warmer air rises above the colder In the northern hemisphere, most fronts travel from west to east carrying clouds and rain.

What is the heat source that causes convection currents?
The sun
400
How does a cold front form?
Fast moving cold air mass over takes a warm air mass
400
What is a similarity between temperatures of areas on the Globe and hurricanes?
Hurricanes form over warm oceans, where the surface temp is warmer

Why do we need to understand the symbols on a weather map?
A weather map and its symbols are meant to convey a lot of weather information quickly and without using a lot of words. Just as equations are the language of mathematics, weather symbols are the language of weather, so that anyone looking at a map should be able to decipher the same exact information from it.

What are the four types of air masses and where does each form?
Polar forms over cold areas, tropical forms over warm areas, continental forms over land, and maritime forms over the oceans.
400
At the _________ hot air rises creating _______ _______
Equator, Low pressure

How does an occluded front affect weather?
Occluded fronts usually form around areas of low atmospheric pressure. There is often precipitation along an occluded front. Wind changes direction as the front passes and the temperature either warms or cools.

3 things a hurricane needs to form
Warm ocean water
winds coming
winds outward
humid air rising
light winds outside hurricane

How do they affect weather patterns
By creating fronts and jetstreams.

What causes weather patterns to change?
Daily? Seasonally?
winds and storms. Seasonal changes are due to the Earth revolving around the sun.
