Wind & Climate Wind – the horizontal movement of air. Low pressure – warm air rising. High pressure – cold air falling. Winds always blow from high pressure.

Winds What causes winds?.

Global Winds. Air Movement Wind is the movement of air caused by differences in air pressure Wind is the movement of air caused by differences in air.

Warm air near the Earth’s surface rises and then cools as it goes back up. Convection happens on a global scale in the atmosphere and causes global winds,

Presentation transcript:

Chapter 5 – Earth’s Weather Lesson 2 – Air Currents and Wind

Why are temperatures different? Sunlight hits the Earth at different angles. 180° 135° 90° equator

Why are temperatures different? Direct beams of light (90°) create more heat than slanted beams. 180° 135° 90° equator

Why are temperatures different? Places near the equator get more direct sunlight, so they are warmer than places to the north or south. 180° 135° 90° equator

How is air pressure different over land and water? sea breeze: air moves from high pressure (over water) to low pressure (over land). land breeze: air moves from high pressure (over land) to low pressure (over water).

What are global winds? As temperature goes up, air pressure goes down. As temperature goes down, air pressure goes up.

What are global winds? Air always moves from areas of high pressure to areas of low pressure. Just think of rolling a ball on a slope – it goes from high to low! High Low

What are global winds? convection: the rising and falling of gas or liquid in a continuous cycle When convection happens in air, it forms winds. global winds: winds that blow in predictable directions over long distances
