Explanation: Wind vanes are used to measure wind direction. The vane points into the wind. For a more accurate reading, make arrow smaller than video shows (wanted it to be easily seen)!

Atmospheric scientists have developed an algorithm that uses data from water vapor movements to measure wind. This could help predict extreme events like hurricanes. Wind speed and direction provide ...

Wind speed measurement has long been a cornerstone of meteorological observation, renewable energy assessment and aeronautical research. The performance of anemometers—devices designed to accurately ...

Martian landers have been able capture measurements of wind speeds -- some gauging the cooling rate of heated materials when winds blow over them, others using cameras to image 'tell-tales' that blow ...

If you're looking for wind energy, the sweetest breezes blow over the open sea. But gathering this energy is risky business, as the strength of offshore winds can easily overwhelm a turbine designed ...
