Coastal Winds
- Sea Breeze - day time as air warms faster over land, rises, cooler air moves from water towards land
- Land Breeze - night time as air rises over still-warm water, cooler air moves from land to water
Orogenic (mountain winds)
- Rising Winds- day time, air moves up slope as it warms
- Falling winds- night time, air moves down slope as it cools
Rainshadow - deserts form on leeward side of mountains that are receive moist winds. Air rises, cools and condenses to release moisture on windward side, dry air descends other side
Objectives and Vocabulary: #content
Lesson: Wind
- Relate the force of high and low pressure to the movement of air.
- What are the three major zones of wind that are found on a global scale?
- 2 regions of little or no winds exist- Names? Locations? Explanations of lack of wind?
- Describe the general location and pattern of motion of the jet streams.
- What/how does the Beaufort Scale measure?
- Coastal areas (and areas near steep terrain) experience different wind patterns at day and at night. Explain/diagram this.
- Describe/diagram the “rainshadow.”

Activity - Beaufort Scale - students illustrate their own version to show the range of winds and their effects
- variations include showing the examples and video in the slideshow and add a definition to the lecture notes
Beaufort scale - originally used by sailors to describe winds at sea, it ranges from 0 "calm" to 12 "hurricane force"
Diagrams - Regional Winds - create simple diagrams for the students to draw in their notes to illustrate the concepts
