| An instrument used to measure wind speed. |
|
|
Term
|
Definition
| ...Differences in air pressure caused by the uneven heating of Earth's surface by the Sun. |
|
|
Term
|
Definition
| Caused because water heats more slowly than land, causing a low pressure area on land. Sea Breezes blow towards the land from the sea. |
|
|
Term
|
Definition
| Caused by gravity pushing down on the atmosphere. Is greater at sea level than at higher altitudes. Also can be called barometric pressure. |
|
|
Term
|
Definition
| A device which indicates the direction of the wind. |
|
|
Term
|
Definition
| Rates winds based on wind speed on a scale from zero to twelve, zero being no wind and 12 being a hurricane. |
|

Term
|
Definition
| Moving energy; in motion. Kinetic energy by wind can be used to generate electricity. |
|
|
Term
|
Definition
| A wind that blows predominantly from a single general direction. For example, the trade winds of the tropics, which blow from the east throughout the year, are prevailing winds. |
|
|
Term
|
Definition
| Areas near the equator where there is little to no wind because warm air rises straight up. |
|
|
Term
|
Definition
| Winds that blow from the northeast in the northern hemisphere and from the southeast in the southern hemisphere. Traders relied on these winds to carry their ships to their destination. |
|
|
Term
|
Definition
| Winds that blow from the poles towards the equator that are turned towards the west because of the Coriolis Effect. |
|
|
Term
|
Definition
| Winds that blow between 30 and 60 degrees N and S. They are turned towards the east because of the Coriolis Effect. |
|
|
Term
|
Definition
| Located at about 30 degrees N and S latitude. Cold air sinks here and there is little to no wind, similar to the doldrums. |
|
|
Term
|
Definition
| Bands of high-speed winds about 10 km above Earth's surface. Blow from west to east at speeds of 200-400 km/hr. |
|
|
Term
|
Definition
| Contribute to the forming of global winds. At ground level, dense, cold air from the poles moves towards the equator where there is lower pressure. Higher up, air moves towards the poles. |
|
|
Term
|
Definition
| A current moving contrary to the direction of the main current, especially in a circular motion. |
|
|
Term
|
Definition
| Any wind that changes directions with the seasons. |
|
|
Term
|
Definition
| A wind with a speed greater than 64 knots (74 miles per hour; 119 kilometers per hour), according to the Beaufort scale. |
|
|
Term
|
Definition
| An atmospheric system characterized by the rapid inward circulation of air masses about a low-pressure center, usually accompanied by stormy, often destructive weather. Cyclones circulate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. |
|
|
Term
|
Definition
| A tropical cyclone or hurricane of the western Pacific area and the China seas. |
|
|
Term
|
Definition
| A rotating column of air ranging in width from a few yards to more than a mile and whirling at destructively high speeds, usually accompanied by a funnel-shaped downward extension of a cumulonimbus cloud. |
