Wind The horizontal movement of air from areas of high air pressure to low

Wind The horizontal movement of air from areas of high air pressure to low air pressure Difference in air pressure due to unequal heat from the sun

H Cold Air High Pressure More Dense L Warm Air Low Pressure Less Dense

H Cold Air High Pressure More Dense L Warm Air Low Pressure Less Dense Molecules like to move from a crowded area to a less crowded area

Isobars mark areas with the same air pressure

 Naming Wind The name of the wind tells you where the wind is

Naming Wind The name of the wind tells you where the wind is coming from. Ex: North wind comes from North (to South) H L N W E S Ex: West wind blows from the West to the East.

 Local Winds that blow over short distances Caused by unequal heating of Earth’s

Local Winds that blow over short distances Caused by unequal heating of Earth’s surface within a small area. Ex: land breeze and sea breeze

Sea Breeze Land air around land warm up faster than water Wind blows toward

Sea Breeze Land air around land warm up faster than water Wind blows toward land from the water

Land Breeze Land also cools faster than water At night, a wind blows toward

Land Breeze Land also cools faster than water At night, a wind blows toward the water from the land

Global Winds that blow over long distances due to unequal heating of Earth’s surface

Global Winds that blow over long distances due to unequal heating of Earth’s surface (more heat at equator)
