Question
Answer
front   boundary between the two air masses  
cold front   formed when the leading edge of cold dense air pushes under warm, light air  
warm front   occurs when warm, light air rises over a cold air mass  
stationary front   form when two air masses meet but are unable to overcome with another  
occluded front   when a cold air mass, a cold air mass, and a warm air mass meet  
cirrus   high altitude, very thin, made mostly of ice crystals  
stratus   low altitude clouds, layered, spread out cloulds, made of water droplets, but can hold ice or even snow if the temperature is cold enough  
cumulus   tall, vertical clouds, fluffy, cotton ball  
Coriolis effect   the deflection of air and oceans because of the Earth's rotation  
Polar Easterlies   coming from the east, rise  
Prevailing Westerlies   coming from the west, rise at 60º N/S and sink at 30º N/S  
Northeast/Southeast Tradewinds   rise at the equator and sink at 30º N/S turning west as they go  
Doldrums   the weather rarely changes at the equator because of the constantly rising air  
alto   mid altitude, thicker than cirrus clouds, slightly spread out, made mostly of water droplets but can have ice crystals if the temperature is cold enough
