Front Notes
• Front: boundary between two different air masses
The weather condition occuring at fronts is
precipitation (ex: rain, snow, sleet) and clouds.
• Cold fronts: curved boundary, heavy downpour rain, air
masses moving in opposite directions (ex: thunderstorms,
tornadoes).
• Warm Front: straight boundary, drizzle for several days,
air masses moving in same direction
• Occluded Front: collision of warm front with cold front
• Stationary Front: warm and cold air masses moving in
opposite directions at same speed; two curved
boundaries; a tug-of-war
• Cyclones: bad weather; Low, Left, inward
• Anticyclones: nice weather; high, right, outward
