  • The internationally recognized Beaufort Wind Force Scale classifies wind into 13 levels (0-12), later extended to 17 for hurricanes:

    Force 0 (Calm): <0.3 m/s, smoke rises vertically1.

    Force 1-3 (Light/Breeze): 0.3-5.4 m/s, leaves rustle2.

    Force 4 (Moderate Breeze): 5.5-7.9 m/s, dust lifted.

    Force 5 (Fresh Breeze): 8.0-10.7 m/s, small trees sway.

    Force 6 (Strong Breeze): 10.8-13.8 m/s, wires hum.

    Force 7 (Near Gale): 13.9-17.1 m/s, walking hindered.

    Force 8-9 (Gale/Strong Gale): 17.2-24.4 m/s, branches break.

    Force 10-11 (Storm/Violent Storm): 24.5-32.6 m/s, trees uprooted3.

    Force 12 (Hurricane): ≥32.7 m/s, severe devastation4.

    Force 13-17: Reserved for typhoons (>37 m/s).

    Note: Modern meteorology uses precise speed measurements (m/s, km/h, or knots), but the Beaufort Scale remains5 a key reference for descriptive wind classification.

    蒲福风级将风力分为13级(0-12级),后扩展至17级(用于台风等超强风力):

    0级(无风):风速<0.3米/秒,烟直上。

    1-3级(轻风/微风):风速0.3-5.4米/秒,树叶微动。

    4级(和风):5.5-7.9米/秒,吹起尘土。

    5级(清风):8.0-10.7米/秒,小树摇摆。

    6级(强风):10.8-13.8米/秒,电线有声。

    7级(疾风):13.9-17.1米/秒,步行困难。

    8-9级(大风/烈风):17.2-24.4米/秒,折毁树枝。

    10-11级(狂风/暴风):24.5-32.6米/秒,拔起树木。

    12级(飓风):≥32.7米/秒,毁灭性破坏。

    13-17级:专指超强台风(>37米/秒)。
