Air Masses and Fronts
A large body of air
What is an air mass?
On a weather map, when it shows green in your area in means:
What is light precipitation?
Stream like movements of water that occur at or near the surface of the ocean
What are surface currents?
Streamlike movements of ocean water far below the ocean surface
What are deep currents?
Brings cold, stormy weather
What is a cold front?
When a weather map shows an area having lower pressure, it means the weather will be:
What is snowy, colder weather?
The two types of currents
What are deep and surface currents?
The measure of saltiness in the water
What is salinity?
There's 4 kinds of these. Warm, cold, occluded, and stationary
What is a front?
When a weather map shows an area having high pressure, it means the weather will be:
What is warmer, sunny weather?
Transports 25 times more water than all of the rivers in the world combined
What is the Gulf Stream?
This happens when the water becomes saltier and colder
The type of mass front that brings less intense precipitation
What is a warm front?
A type of front shown on a weather map with blue triangles on a map
What is a cold front?
When these blow across earths surface, surface currents are created
What are global winds?
Deep currents are caused by changes in this. It's affected by salinity and temperature.
What is density?
A boundary between a cold front and a warm front. Brings fair weather
What is a stationary front?
A type of front shown on a weather map with red semi-circles
What is a warm front?
Occurs when surface currents collide with land and change direction
What is continental land deflection?
This gets colder as depth increases
What is water?
