Winds Learning Objectives  Explain how scientists describe and explain winds.  Distinguish between local winds and global winds and identify major.

Convection Currents  An area of Earth’s surface is heated by the sun’s rays.  Air over heated surface expands and becomes less dense and the air pressure.

Winds Chapter 16 Section 3

What is wind? Horizontal movement of air from an area of high pressure to an area of lower pressure Caused by differences in air pressure Most differences are caused by unequal heating in the atmosphere

What is wind? Air over a heated surface becomes less dense and air pressure decreases Dense air from a nearby cooler area with higher pressure will move in and force warm air to rise

Measuring Wind Described by speed and direction A wind vane indicates direction An anemometer indicates speed

Wind Chill Factor How cold it feels due to the wind Wind removes body heat thus feeling colder

Local Winds Winds caused by unequal heating in a small area Sea Breeze – blows from a lake or ocean Land breeze – flows from land to a lake or ocean
