How many winds are blowing at sea? Can't a ship go out to sea?

Generally, cargo ships can't go when the wind force is around 7. Some boats in Qiongzhou Strait can sail when the wind is level 8, and some boats can sail when the wind is level 6.

The ship inspection certificate of each ship will have the wind resistance rating of the ship, and each ship must sail in strict accordance with this wind resistance rating. If the wind level of the sea area it passes through is higher than the wind resistance level, it will stop sailing.

According to the phenomenon caused by the wind to the ground objects, the magnitude of the wind force is divided into 13, and the expression of "Dongfeng Level 3" that people usually hear in weather forecast is "Beaufort Wind Level".

Extended data:

Due to the difference of wind speed, wind direction and humidity, many types of wind will be produced. Blast, gale, gale, gale, storm and hurricane, these common wind types, Beaufort wind force are seven, eight, nine, ten, eleven and twelve respectively.

Gust: When the air speed is high and low, the wind will be high and low, and there will be waves of feeling when blowing on people. This is a recognized gust of life.

Meteorology, wind speed usually refers to the average situation within 2 minutes, with high or low wind speed, and gust usually refers to the maximum instantaneous wind speed during this period. If the weather forecast, today's wind is 4-5, and the gust is 6, which means that today's average wind is 4-5, and the maximum instantaneous wind can reach 6.
