1
Winds Difference in air pressure Horizontal movement of air
High pressure moves to low pressure Unequal heating off air Warmer expands = less dense = less air pressure Cooler expands = more dense = higher air pressure What causes winds? What changes air pressure?
3
How is wind measured? What is the wind-chill factor? Direction – wind vane Named for where they come from. Ex. Blows south comes from north Measured with anemometer Wind turns cups Cooling effect from wind Stronger wind = cooler the feeling
4
What are local winds? Unequal heating of air in small area Often occurs where land is by large body of water.
5
Land Breeze – Nighttime Draw this picture then take notes
Land cools faster than water – cools air above cool air move out to sea pushes warm air up 2. Water stays warmer than land – air stays warmer warm air rises
6
Sea Breeze – Daytime Draw this picture then take notes
Water is warms slower than land – cooler air above cool air moves towards land pushes warm air up. 2. Land warms faster than water – warm air rises pushes warm air up
7
Just a different picture for you to look at!! NOTICE!!
Sea Breeze Wind comes from the sea Land Breeze from the land
8
Other Local Winds Draw pictures then take notes
Daytime Air warms rises breeze up the mt. Nighttime Air cools sinks breeze down the mountain
9
What is a monsoon? South and Southeast Asia A large Sea Breeze in the summer

Literacy Do Now: 3/21 1. Open a Science Text Book to page 758. Today
~ Read pages 754 out loud in class ~ Complete the Observation and Inference worksheet – will be collected today. When you finish the worksheet you may read quietly or work on homework. HW: I did not leave the quiz – it will be Monday so, study the scientific method, observation and inference definitions
