a huge body of air that has similar temperature, humidity, and air pressure at any given height
a swirling center of low air pressure
A high-pressure center of dry air
the boundary where unlike air masses meet but do not mix
bands of high speed winds above 10 kilometers above Earth's surface
cut off, as in a front where a warm air mass is caught between two cooler air masses
Warm air masses that form in tropics and have low air pressure
cold, high pressure air masses that form north of 50〫north latitude or south of 50〫latitude
humid air masses that form over oceans
drier air masses that form over land
Prevailing westerlies and jet streams
move air masses from west to east
West to east
Direction of air masses
A warm air mass overtakes a cold air mass
a cold air mass overtakes a warm air mass
a warm air mass is caught between two cooler masses
warm air mass and cold air mass meet "head on"
thunderstorms, shift in wind, lower temperature
