What is the symbol of strong wind?

The symbol of the strong wind sign is four bars of F, and the sign of the wind is as follows:

Wind direction: expressed by vector pole, indicating the direction of wind. The direction of the wind direction is based on the longitude and latitude lines on the map. That is to say, if a person gets a weather map, he will make the latitude horizontal, up north and down south. After observing the wind vane, the vertical direction of F refers to the direction that the wind blows away, which is expressed by the wind vector and consists of wind stems and wind plumes.

Extended data:

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 releasing the weather forecast, the formula is "from all the way to nine, all levels are multiplied by two." It means: from 1 to 9 winds, multiply each level by 2, and you can roughly get the maximum wind speed. For example, the maximum speed of the first wind is 2 meters per second, the second wind is 4 meters per second, the third wind is 6 meters per second, and so on.
