What is Wind Speed?
Wind speed refers to the rate of movement of air over a specified period of time. It is measured in meters per second (m/s), kilometers per hour (km/h), or knots (kt).
Wind speed can deflect the flight angle of the rocket. Therefore, it is an important factor in calculating the rocket’s flight profile.
Methods for Measuring Wind Speed:
- Anemometer: A device used to directly measure wind speed. Various types include:
- Cup Anemometer: Measures speed through rotating cups driven by the wind.
- Ultrasonic Anemometer: Calculates speed by measuring the time taken for sound waves to be carried by the wind.
- Doppler Radar: Measures speed using the Doppler effect of the wind.
- Pitot Tube: Calculates speed by measuring dynamic and static pressures of the air.
Factors Affecting Wind Speed:
Atmospheric pressure leads to pressure differences, causing the formation of wind. Terrain features such as mountains, valleys, and coastlines can influence wind direction and speed by directing the movement of air. Temperature variations affect air density, which can influence wind speed. The Earth’s rotation also influences wind formation; the Coriolis effect affects wind direction, causing it to curve in a certain tendency. The combination of these factors creates a complex interaction of atmospheric movements, determining the development of meteorological events overall.
