Fronts
What is a front?
A boundary between two air masses with different temperatures
What directions do jet streams flow?
They flow from West to East
What causes convection currents?
Differences in air temperatures and pressure
What is a land breeze?
Winds that blow from the land to the ocean.
What is wind?
Wind is moving air in the atmosphere.
What happens when a cold air mass pushes into a warm air mass?
The cold air mass pushes under the warm air mass, causing precipitation.
How does the jet stream affect weather in the US?
It moves weather systems from West to East and can block cold air from the poles
What is an air mass?
A large body of air with uniform temperatures and humidity
What is a sea breeze?
Winds that blow from the ocean to the land
What is a tornado?
Destructive rotating column of air that can cause significant damage
What is a stationary front?
A front where neither air mass is strong enough to push the other out, resulting in unchanging weather
What effect does the jet stream have on storms?
The jet stream can move storms and other weather systems
What is the role of temperature in convection currents?
Temperature differences causes warm air to rise and cool air to sink.
How do land breezes form?
Land breezes form when the land cools faster than the ocean at night
How does wind affect the weather?
Wind moves air and helps stabilize temperatures
What is the difference between a cold front and a warm front?
A cold front pushes under warm air, while a warm front moves over cold air
What is the typical speed of jet streams?
Jet streams flow at speed up to 200 mph
Why does warm air rise?
Warm air rises because it is less dense than cool air
Why are sea breezes cooler during the summer?
Sea breezes are cooler because the air over the land heats up faster than the land over the ocean
How does wind keep temperatures stable
Wind helps distribute temperatures and moving air from one location to another
Describe the weather associated with a stationary front
Weather associated with a stationary front typically includes several das of unchanging weather
What role does jet streams play in blocking air masses?
It can block cold air from moving down from the poles or warm air from the equator
They can lead to challenging local weather patters such as breeze formation
Compare and Contrast Land & Sea Breezes
Land Breezes blow from the cool land to the warm water; while Sea Breezes blow from the cool water to the warm land
