local winds

global calm areas

The westerlies and polar easterlies
is a very large collection of air that has uniform temperature, humidity, and air pressure

air mass
the boundary where air masses meet

front
bodies of air that have different tempatures also have different

densities and air preasure
faster moving warm air collides with a body of cold air and causes the warm air to rise above the cold air

cold front
what are lines that that show areas with similar air pressure

isobars
a wind that changes direction with the change of seasons and which usally brings heavy rain fall

monsoon
are classified by their temperature and humidity

air masses
