Air Masses and Fronts
What is an air mass?
A large body of air that has the same temperature and moisture level throughout.
What's a weather map?
A map showing the state of the weather over a large area.
How many types of ocean currents are there?
2 types
What is a Deep current?
are streamlike movements of ocean water far below the ocean surface.
What is a front?
The boundary where two air mass's meet and weather occurs.
What direction does the weather move?
West to East
What is a surface current?
Stream-like movements of water that occur near the surface of the ocean.
When does the water start to get colder in deep ocean currents?
200 meters
How many different types of air masses are there?
4
What type of weather does California have?
Sunny weather
What type of weather does surface currents carry?
Warmer, less dense weather.
What are deep currents controlled by?
Changes in water density
What's a cold and dry air mass
Continental polar
What type of weather does Denver have?
Cold snowy weather
What does the warm water from surface currents replace?
Cold denser water
Is the East Australian current fast?
Yes
What is the relationship between air masses and fronts?
A weather front is a transition zone between two different air masses at the Earth's surface
Why is California always warm?
Because warm fronts move slowly due to low energy
What do surface currents cause?
changes in the atmosphere that disrupt the climate in many parts of the world.
Where does the deep current carry the cold and dense water too?
From the poles to the equator.
