Understanding Global Wind Patterns and the Coriolis Effect

Explore the relationship between the Coriolis effect and global wind patterns, learning how the Earth's rotation influences wind direction and the formation of major wind systems like Polar Easterlies, Prevailing Westerlies, Trade Winds, Horse Latitudes, and Doldrums. Understand the role of convection cells, high and low pressure areas, and the impact of geographic features.

Presentation Transcript

1. Objective between the Coriolis effect and global wind patterns DO Objective: : Describe the global wind patterns & explain the relationship DO NOW NOW Update T.O.C. Take out H.W. (Markup of land/sea & mtn/valley breezes sheets) Update Agenda: HW worksheet. In your notes, add heading: Wind patterns Respond to the following: Imagine you re near an ocean in the daytime. You want to go swimming but don t know how get there. How might a local wind help you find the ocean? Review notes on Local Winds. HW: Complete the global and local winds

2. DEMO: Coriolis effect on a whiteboard!

3. The Coriolis effect is is the apparent curving of the moving from an straight path to rotation. . Coriolis The effect apparent of moving from straight to rotation the curving path of object an otherwise path due the the path of a a object otherwise due the Earth s Earth s Coriolis Effect Animation

6. Coriolis Effect Animation

7. Global winds convection cells and Flow primarily from 1 direction over long distances High to Low pressure Not influenced by local geographic features to determine direction Global winds are caused by a combination of the convection cells and the Coriolis effect. are caused by a combination of the Coriolis effect. The 3 major global wind systems include: Polar Easterlies Prevailing Westerlies Trade Winds The Horse Latitudes The Doldrums

8. Warm, less dense air rising Warm air creates low pressure area Cold, dense air sinking Cold air creates high pressure area

9. The Earth spins this way
