- Weather vanes are used to indicate wind direction.
- Anemometers are used to measure wind speed.
- A knot is a unit often used to measure wind speed
- Sea breezes occur because heat from the Sun takes longer to warm the sea than the land, creating a difference in air pressure.
- Wind can provide energy through the use of wind turbines.
- Sailing ships use wind to power their movement with the help of sails.
- Many sports and recreational activities make use of the wind, these include kite boarding, wind surfing, sailing and paragliding.
