1. Aim: How can we explain weather fronts?

2. Weather Fronts Where two air masses of different characteristics meet
Most storms form near fronts
Front symbols point in the direction of travel

4. In our area, weather fronts and systems travel NORTHEAST

5. Cold Front
Boundary between advancing cold air mass and a warm air mass
Thunderstorm-type clouds
Intense precipitation at front edge
Passes quickly

9. Warm Front
Boundary between advancing warm air mass and retreating wedge of cold air mass
Precipitation ahead of the front
Takes a longer time to pass

13. Stationary Front
Two air masses of different characteristics remain in the same position
Noticeable temperature change and/or shift in wind direction is observed when crossing front

15. Occluded Front Boundary between opposing cold air masses
Formed when cold front overtakes warm front and pushes warm air completely off the ground
Large areas of rainy weather
