Air Masses
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.
What are 3 types of information you can find on a weather map?
Air temperature (in degrees Fahrenheit) Dewpoint temperature (degrees Fahrenheit) Current weather
What causes most surface currents?
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the Sun.
How deep are ocean currents found?
below 300 meters (984 feet)
What are the 4 types of air masses?
arctic, tropical, polar and equatorial.
What would you find on a weather map?
weather conditions for a certain area
What affects the currents on the surface of the ocean?
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the Sun.
What controls deep ocean currents?
temperature (thermo) and salinity (haline).
Which of the following is most likely to be true of a continental polar (cP) air mass?
A. It is cold and humid
B. It was formed over the Rocky Mountains
C. It developed in a cold, very rainy region
D. It is cold and dry
E. It is not able to move as far south as the U.S.
A. It is cold and humid
How do you read weather front maps?
A stationary front is depicted by an alternating red and blue line with a triangle on the blue portion and half-moon on the opposite side of the red portion of the line. A cold front (or warm front) that stops moving becomes a stationary front.
In general, how do currents that flow along the West coasts of continents compare with currents that flow along the east coasts of the continents?
they are much more intense
What causes most deep ocean currents?
What is a "fast moving warm air mass that overtakes a slowly moving cold air mass"?
Warm Front
What does H mean on a weather map?
High. A region of high pressure, marked as a blue "H" on a weather map. A high is usually associated with fair weather. See anticyclone.
Which two currents together circle the North Atlantic Ocean?
The Gulf Stream, paired with the eastern boundary Canary Current
Which is the deepest ocean?
western Pacific Ocean
Which direction does the east Australian current travel
South
What do colors on weather map mean?
The greens indicate light or moderate rainfall. Yellow, orange, and red indicate moderate to heavy rainfall and can also indicate hail. Whites or blues mean snowfall and pink indicates freezing rain, sleet, or a wintry mix.
What is the strongest surface ocean current?
The Antarctic Circumpolar Current
How deep are ocean currents found?
below 300 meters (984 feet)
