Extended data

Wind scale, referred to as wind scale, is a representation of wind strength (wind power). 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 wind force is divided into 13, with a minimum of 0 and a maximum of 12.

According to the national standard "Wind Grade" issued in June of 20 12, and according to the wind speed at the height of 10 meter in the standard meteorological observation field, the wind grade is divided into 18 grade in turn. There are three commonly used units to express wind speed, namely nautical mile/hour, meter/second and kilometer/hour, and the commonly used unit for typhoon forecast in China is meter/second.

Twelve winds are jingling.

What we usually call the wind level in our daily life is the meteorological wind level, which is different from the typhoon wind level. See the following figure: meteorological wind level: wind level 0: summary: there is no wind, the land is still, and smoke goes straight to the coast. Equivalent wind speed (m/s) 0.3- 1.5 wind level 1 summary: soft wind land smoke can indicate the direction. However, the wind vane cannot turn the coastal fishing boats. Wind speed is 0.3- 1.5. Wind force 2. The wind on the land feels windy, and the leaves are slightly ringing. Ordinary wind vane can move with the wind by turning the sails of coastal fishing boats. Wind speed 1.6-3.3. Wind force 3. The leaves and twigs on the ground are shaking constantly. When the flag flutters in the wind, the coastal fishing boats gradually feel the considerable wind speed (M/s) of 3.4-5.4. The wind and land can blow up the dust and paper on the ground, and the twigs of trees shake the coastal fishing boats full of sails. The equivalent wind speed (m/s) leaning to one side m/s) 5.5-7.9. The wind level 5 is an overview of the breeze, the small trees on the land are swaying, and the equivalent wave speed (m/s) on the coastal water surface is 8.0-10.7. The wind level 6 is an overview of the strong wind, the big branches on the land are swaying, the wires are whistling, and it is difficult to hold an umbrella. The fishing boats along the coast set up double-sided sails. Attention should be paid to the dangerous equivalent wind speed (m/s) 10.8- 13.8 wind force level 7. The wind is strong, the trees on the land are shaking, and it is inconvenient for coastal fishing boats to stop at the port. The equivalent wind speed for overseas anchoring is (m/s)13.9-17./kloc- Walking in the wind feels great resistance. Ships near the coast can't stay at a considerable wind speed (m/s) 17.2-20.7, and the wind force is 9. The chimney and the roof of the flat building are damaged in the windy field (the chimney and the flat roof are shaking). Steamboats along the coast are difficult to sail. Considerable wind speed (m/s) 20.8-24.4 10 is rare on land. Trees can be pulled up and houses can be destroyed. Steamboat sailing along the coast is quite dangerous (m/s) 24.5-28.4 Wind level 1 1 Overview Storms are rare on land, and some will be seriously damaged. Coastal steamboats encounter extremely dangerous wind speed (m/s) 28.5-32.6 wind scale 12 Overview hurricanes are rare on land and have great destructive power.

Twelve-level wind bell

0-level smoke column goes straight into the sky, 1 level smoke is deflected by the wind, 2-level breeze blows the surface, 3-level leaves move red flags, 4-level branches shake paper, 5-level small trees with leaves shake, 6-level umbrellas are difficult to walk, 7-level wind is inconvenient to walk in the wind, 8-level wind breaks branches, 9-level roof tiles fly, 10-level trees pull up and fall down,1. 1. 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, most of them use the wind level. 2. The distance that the wind moves per second-the wind speed, its formula is "from all the way to nine, multiplied by two". It means: from 1 to 9 winds, multiply each level by 2, and you can roughly get the maximum wind speed.

The first to twelfth winds jingle.

First-class light smoke deviates with the wind; The second breeze blows the face; Three-level moving leaf red flag exhibition; Four-stage branch flying paper; Five-level small trees sway in the wind. Level 6 is difficult to carry an umbrella; It is inconvenient to walk in the wind in the seventh grade; Eight winds blow off branches; Nine-level roof flying tiles; Ten-level uprooting trees and toppling houses; Eleven or two grades are rare. 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, most of them use the wind level. How to determine the series of wind power? The distance that the wind moves per second-the wind speed, its formula is "from all the way to nine, 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. There are also transitional figures between different levels of wind, such as the first level wind 1-2 meters per second, the second level wind 2-4 meters per second, the third level wind 4-6 meters per second and so on. According to the need, wind power can also be converted into corresponding wind speed, that is, the distance that air flows in unit time, in meters per second. The conversion formula is for reference: two to one is one, and three levels plus one. Grades four to nine are not difficult to calculate, and the series is reduced by two times three. Ten to twelve are rare, so ten is easy to remember. Ten-level wind speed is twenty-seven, with one more level every four levels. That is, the wind speed of the primary wind is equal to 1 m/s, the wind speed of the secondary wind is equal to 2m/s, the wind level of the tertiary wind is added with 1, and its wind speed is equal to 4m/s, and the series from 4 to 9 is subtracted by 2, and then multiplied by 3 to get the corresponding wind speed. The wind speed algorithm from 10 to 12 is the same. 10 wind speed is 27m/s, and on this basis, add 4 to get 1 1 wind speed is 3 1m/s, and add 4 to get 12 wind speed is 35m/s ...
