Wind direction and wind speed

Everyone knows the rough concept of wind direction and wind speed. From small to large, we are all speaking or listening to some descriptions about the wind: today the wind is great; the southeast wind is 4-5 and so on. Among the 4-5 winds in the southeast wind, the wind direction and wind speed have already been covered. In the academic definition, the wind direction is the direction of the wind. If the wind blows from the south, it is called the south wind; when blowing from the north, it is called the north wind; and when the wind vacillates from time to time, we can add the word “bias”, such as the northerly wind. There are many ways to represent the wind direction. The common ones are the orientation and angle. On land, we usually use 16 bearings to indicate wind direction, but at sea, we have more, generally 36 bearings. The angle is for the direction of high winds. We divide the circle into 360 degrees, the north wind (N) is 0 degrees (that is, 360 degrees), the east wind (E) is 90 degrees, and so on. The concept of wind direction was introduced in detail earlier. Let's take a look at the concept of wind speed. The wind speed, as the name suggests, is the speed of the wind, in meters/second. In nature, we generally divide the wind speed into 13 levels, from 0 to 12 levels. Level 0 is the solitary scene depicted in the poem “The solitary desert in the desert, the sunset over the long river,” without a slight breeze. The 12th level is the highest level when we divide the wind speed, but in reality there are still more winds than the 12th level. Since we can't appear on the mainland, we avoid talking about it. At this point, we should be very clear about the concept of wind direction and wind speed.

There are many ways to measure the wind direction. The most common ones are flags and wind vanes. When we use the flag to indicate the direction of the wind, the opposite direction of the direction in which the flag flies is the direction of the wind, and the direction of the wind vane is just the opposite. The direction of the wind direction is precisely the direction of the wind. Many people will be confused about this. However, with the progress and development of society, scientific instruments have long been a powerful tool for solving many practical problems. The measurement of wind direction and wind speed mentioned above can be achieved by an instrument. This is the portable wind anemometer developed and produced by Topp in Zhejiang (see http://). This instrument incorporates many high-end technologies, such as touch buttons, LCD display, 60,000 data storage capabilities, manual, automatic, and computer-locked modes, 32-channel simultaneous detection capability, and the ability to connect to computers at the same time to complete data transmission. This powerful feature makes this instrument easy to use and lightweight to carry.

Wind direction and wind speed have a significant role in agricultural production. Measuring the wind speed can guide the growth of crops and produce better yields. Therefore, as an agricultural worker, it is necessary to have a wind anemometer.
