1. Warm-up Wednesday, February 13 Based on the weather outside, answer the questions: 1.What type of pressure system is it? (Low or High) 2.Is it a cold or warm front? 3.What would the isobars on a weather map look like for this type of weather? Cold

2. MYP Unit Question: What should I wear today? Area of Interaction: Environment Learner Profile: Communicator Standard: Understand how the distribution of land and oceans affect climate and weather.

3. Learning Target: Today I’m learning how the temperature of the atmosphere affects weather because it impacts my environment. Opening: Beach Video – which way is the wind blowing? Work Session: Review conclusions of heat lab Video: Global Winds Notes over land and sea breezes Closing: What’s the weather like in

4. Let’s review the lab from yesterday. 1.What type of heating was occurring over the “land” and “ocean?” ( radiation, convection, or conduction) 2.Which one heated up the fastest? 3.Which one cooled the fastest? Land Water

5. In your notebook, page ____ draw this image. Title the page “Land and Sea Breezes.”

6. Under the Land and Sea Breeze image write the following information:  Weather is caused by unequal heating of earth’s surface.  Air moves from areas of high to low areas of concentration (high to low pressure)

7. During the day, the land warms up quicker than the water.  What happens to the warm air above the land?  What replaces the warm air?  Where does the cool air come from? This is called a SEA BREEZE

8. So what do I write down? Sea Breeze  Occurs in the day time  Warm air from land rises up (low pressure)  Cool air from the water replaces it

9.  Why is it cooler on the beach at night than it is during the day?  Where is the warmer air located?  Where is the breeze coming from? This is called a LAND BREEZE

10. Land Breeze  Occurs at night  Warm air from ocean rises (low pressure)  Cool air from the land replaces it

12. Inches to Mill bars (mb) 1029 mb = 30.39 inches 1002 mb = 29.6 inches 1000 mb = 29.53 inches 960 mb = 28.34 inches To convert inches of mercury to millibars, multiply the inches value by 33.8637526
