Pre-Starter Complete your red, amber or green starter activity in your book. Remember which task you are doing depends on how you did on this topic in your baseline test. 5

Global atmospheric circulation Red - To be able to define what atmospheric circulation is and describe surface wind and pressure belt patterns. Amber - To be able to explain how the atmospheric circulation model drives the world’s weather. Green - To be able to compare different weather and climate patterns in different global regions and explain their variation due to global atmospheric circulation.

Starter - Context In pairs, think about: Where would you have rather been yesterday? What causes 3 different places to have entirely different temperatures and weather on the same day?

3 Global atmospheric circulation - Core basics Global - The earth Atmosphere - The air above our heads - mass of swirling gases, liquids and solids such as carbon dioxide and oxygen, water vapour and droplets and ash. Circulation - Circular air movements called cells. These cells all join together to form the overall circulation of the earths atmosphere. Task (All) - Write your own definition for ‘Global atmospheric circulation’ in no more than 20 words. 3

High pressure = Air that is sinking towards the ground The Earth's atmosphere exerts a pressure on the surface. Pressure is measured in hectoPascals (hPa), also called millibars. High pressure = Air that is sinking towards the ground Low pressure = Air that is rising from the grounds surface

10 Task 1 - RAG Using the diagram and information, complete the quick question task (RAG) By the end of this task you should be able to: Say what the diagram shows. Explain what patterns are shown.

Task 2 - RAG - exam application Explain how the global atmospheric system affects the weather and climate of the UK using key terminology. (6 marks) Explain how the global atmospheric system affects the weather and climate of the UK giving evidence from the climate graph and using key terminology. (6 marks) Compare the weather and climate of hot deserts and equatorial areas. Explain how the atmospheric circulation system affects these climates, giving evidence from the climate graphs. (8 marks) 15

Compare your exam answer with a model How does your response compare? What can you add or do differently? 10 Improvement options : Add to/re-write your exam answer using the model. Write instructions for somebody to use if they were to complete your question. Do this as a step- by-step guide including what improvements you would need to make. Choose the next up question if you are happy with your first response.

Plenary Complete the green starter questions from the beginning of todays lesson. What progress have you made? Weather hazards R A G 1. General atmospheric circulation model; pressure belts and surface winds. X 2. Global distribution of tropical storms (hurricanes, cyclones and typhoons) 3. The relationship between tropical storms and general atmospheric circulation 4. Causes of tropical storms and the sequence of their formation and development 5. The structure and features of a tropical storm. 6. How climate change might affect the distribution, frequency and intensity of tropical storms. 7. Primary and secondary effects of tropical storms with a named example. 8. Immediate and long-term responses to tropical storms with a named example. 9. How monitoring, prediction, protection and planning can reduce the effects of tropical storms. 10. Types of weather hazard experienced in the UK. 11.1 Causes of a recent extreme weather event in the UK. 11.2 Social, economic and environmental impacts of a recent UK weather event (same) 11.3 How management strategies can reduce the risk of extreme weather events in the UK. 12. Evidence that weather is becoming more extreme in the UK. PLC update
