1. Air Fronts

2. Fronts: Cold Warm Stationary Occluded Boundary between two air masses
Characterized by shift in weather
Cold
Warm
Stationary
Occluded

3. Fronts and their symbols

4. 5 Characteristics of a Front
Sharp temperature changes over a relatively short distance.
Changes in air moisture content
Shifts in wind direction
Pressure changes
Clouds and precipitation

5. Cold Front Warm Front Both Heavy Rain Fair Cool weather follows
Steeper Slope
High pressure
Move east to west
Slow steady Rain
Hot humid weather
Steeper Slope
Low Pressure
Both can
bring rain

6. 5 Characteristics of a Front
Sharp temperature changes over a relatively short distance.
Changes in air moisture content
Shifts in wind direction
Pressure changes
Clouds and precipitation

7. Fronts: Boundary between two air masses
Characterized by shift in weather

8. Cold Front
Moves in this direction
Rain/Thunderstorms

9. Cold Front Heavy Rain Fair Cool weather follows Steeper Slope
High pressure
Typically move faster than warm front

10. Warm Front

11. Warm Front Slow steady Rain Hot humid weather Steeper Slope
Low Pressure

12. Occluded Front

13. Stationary Front

14. Stationary Fronts Temperature – stagnent
Pressure – slightly fluctuates
Clouds – altocumulus
Precipitation – none
Winds – variable and light
Can last for days weeks

15. Occluded Front

16. Occluded Fronts Temperature – Pressure – Clouds – cumulus
Warm – gets milder
Cold – gets colder
Pressure –
Warm - slight drop
Cold – slight rise
Clouds – cumulus
Precipitation – steady and light
Winds – variable and light
