How big is the gale of magnitude 8?
Wind power refers to the strength of the wind blowing on an object. Generally speaking, according to various phenomena caused by wind blowing on objects on the ground or water surface, the magnitude of wind power is divided into 18, with the smallest being 0 and the largest being 17.
Wind speed is the forward speed of the wind. The greater the air pressure difference between two adjacent places, the faster the air flow, the greater the wind speed and the greater the wind force. Therefore, the magnitude of wind is usually expressed by wind power. The unit of wind speed is meters per second or kilometers per hour. When the weather forecast is released, the wind level is mostly used.
