Fronts and Air Mass Modeling Make Up Assignment

Warm-Up There are 5 definitions on the first paper of the demo. Draw a model of what is being described in each definition. Front Cold Front Warm Front Occluded Front Stationary Front

DEMO 1 The first front that was modeled was one that forms when: A cold or warm front stops moving The air masses are not powerful enough to move or overpower the other This front stays stationary for an extended time. Complete DEMO 1

DEMO 2 prediction We will release the barrier between the red (warm water or “air”) and the blue (cold water or “air”) In your notebook: Predict what you will see after 5-10 seconds.

DEMO 2 – cold and warm fronts Notice that we are modeling 2 different fronts here (the black line is the marker dividing the two types). ABOVE THE LINE: warm “air” is replacing cold “air” BELOW THE LINE: Cold “air” is replacing warm “air” In your notebook: Draw the model at ~25 seconds

DEMO 2 – complete questions 1-4 Warm front #2. Draw what is below the black line (both air masses represented. Include arrows to show movement. #3. Draw what is above the black line (with both air masses represented). Include arrows to show movement. cold front
