Air Masses & Fronts
Brings cold stormy weather
What is a cold front
Shows a state of weather over a large body of land
What is a weather map
stream like movements of water
What is a surface current
These are stream like movements far below the surface
what is a deep current
A transition zone between two different air masses
What is a front
Shows up on a weather map with red triangles
What is a warm front
causes surface currents to move in curved paths rather than in straight lines
What is Earth's rotation
controlled by water density
What is a deep current
It has temperature and moisture and is in the atmosphere
What is an air mass
Has blue triangles over a body of land
What is a cold front
They are controlled by global winds, Coriolis effect, and continental deflections
What is a surface current
This happens to the ocean when it gets saltier and colder
What is denser
Slow moving and is warm
What is a warm front
The letter H over a part of land
What is high pressure
this transports 25 times more water than any of the worlds other rivers
What is the gulf stream
Surface currents carry this from the equator to the poles
What is warmer, less dense water
Will stay until a stronger mass pushes it out
What is a stationary front
Has blue triangles on one side and red half circles on the other and can be shown on a weather map
What is a Stationary front
occurs when surface currents collide with land and deflect or change direction
What is a continental land deflection
This happens at the depth of about 200 meters
what is colder
