About Wind Speed
Wind speed measures how fast air is moving through the atmosphere. It is typically measured using an anemometer and can be expressed in miles per hour, kilometers per hour, meters per second, or knots.
Understanding wind speed helps interpret weather conditions, from calm air to storms. The Beaufort scale provides a simple way to describe wind strength based on observed conditions.
