1. Explain the importance of the jet stream to weather conditions experienced in the Midwest (5)

2. Draw a diagram to show the relationship between convergence, divergence, cyclone and anticyclone (3)

3. Explain the relationship between stability and cloud development. Why is atmospheric lifting significant in cloud development (5)

4. Explain the controls on global temperature patterns (4)

5. Winds are generated by a balance of forces. Demonstrate with two examples.(4)

6. Explain how ocean currents may influence humidity over land (3)

7. Cyclones by definition are low pressure storms which occur at a range of scales. Give three examples and indicate their relative spatial size. (3)
