| wind | The horizontal flow of air. (pg. D38) |
| convection cell | A pattern of rising air, sinking air, and winds. (pg. D38) |
| sea breeze | A motion caused by the air over land rising and then the air over the water moves in to replace the rising air on land. (pg. D39) |
| land breeze | A motion caused by the air over land cooling more quickly at night than the air over water; then the wind blows from the land toward the water. (pg. D39) |
| Coriolis effect | As Earth spins (rotates), winds in the Northern Hemisphere seem to curve toward the right as they blow toward the south. In the Southern Hemisphere, the curving action is in the opposite direction. (pg. D40) |
| isobars | A series of lines on a weather map that indicate high pressure and low pressure areas. These lines connect places of equal air pressure. (pg. D42) |
| weather vane | A tool that indicates the direction of wind movement. The tip points in the direction the wind is blowing from. (pg. D44) |
| anemometer | A tool that measures wind speed. (pg. D44) |
