Apparent wind information

Apparent wind is the wind experienced by a moving object. The apparent wind is the wind experienced by an observer in motion and is the relative velocity...

An apparent wind indicator, as found on sailboat, is a small weather vane or arrow that gives an indication of the current apparent wind direction. This...

sail contributes to the "apparent wind"—the wind speed and direction as measured on the moving craft. The apparent wind on the sail creates a total aerodynamic...

Apparent magnitude (m) is a measure of the brightness of a star or other astronomical object. An object's apparent magnitude depends on its intrinsic luminosity...
