Air Masses + Fronts
What air mass temperature is low pressure?
Hot
What does the blue “H” mean on a weather map?
High pressure
What is the main cause for surface currents?
Winds
What causes deep currents?
Density
What air mass temperature is high pressure?
Cold
What does the red curve with triangles mean on a weather map?
Warm front
Does the Atmosphere have to do with surface currents?
Yes, winds cause surface currents to move, and winds need the atmosphere.
Lower temperatures means this is higher.
Density
What pressure does a cyclone have?
Low pressure
How can you predict the weather of an area over the next couple of days?
Pay attention to the way the wind travels to predict.
What causes the Coriolis Effect?
More of this in ocean water causes a higher density.
Salt
What front in the U.S. would come from Canada?
Tropical polar
What temperature is low pressure on a weather map?
Warm temperature
What does the Coriolis Effect do to surface currents?
It makes the paths all curvy.
True or false: deep currents start 300 feet underwater.
False
Which areas of pressure do the wind coming out of an anticyclone move to?
Low pressure areas
What does the curve on the map with triangles and half circles on it mean on a weather map?
Stationary front
What does continental deflection do to surface currents?
They change direction.
What unit of measure is density usually measured in?
g/cm3
