Hurricanes: Science and Society: Hurricane Movement
Global winds drive the ocean's surface currents as well as the direction of hurricane propagation. The persistent easterly trade winds in the tropics (~0 to 30°N and ~0 to 30°S) and the Westerlies in the mid-latitudes are the Earth's major wind fields that impact hurricane movement.

Given the complexity of the building, it was
Wind Energy Basics | NREL
Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more above ground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind's energy with their propeller-like blades. Usually, two or …

How a Wind Turbine Works - Text Version | Department of Energy
How a Wind Turbine Works. A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates ...

Self-study notes - GAUSSIAN PLUMES
It may be seen that the turbulence intensities, especially the vertical wind speed fluctuations, increase as atmospheric conditions become more unstable. One other factor that needs to be considered in practice is the plume rise (∆h). This is the path or trajectory of the plume centre-line after it leaves the source.

Windmill - Wikipedia
The horizontal-axis or vertical windmill (so called due to the plane of the movement of its sails) is a development of the 12th century, first used in northwestern Europe, in the triangle of northern France, eastern England and Flanders. It is unclear whether the vertical windmill was influenced by the introduction of the horizontal windmill to Southern Europe in the preceding century.

How do wind turbines work? | Good Energy
Wind turbine blades rotate when hit by the wind. And this doesn't have to be a strong wind, either: the blades of most turbines will start turning at a wind speed of 3-5 meters per second, which is a gentle breeze. It's this spinning motion that turns a shaft in the nacelle – which is the box-like structure at the top of a wind turbine.

How Do Wind Turbines Work? | Department of Energy
Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity. Wind is a form of solar energy caused by a combination of three concurrent events:
