Wind wind
Usually refers to the horizontal motion component of air, including direction and magnitude, that is, wind direction and wind speed. But for flight, it also includes vertical motion components, so-called vertical or ascending and descending airflow. Gust (also known as gust) is the wind whose wind speed changes dramatically in a short time. Meteorological wind direction refers to the direction of the wind, and navigational wind direction refers to the direction of the wind. In meteorological service, the grade of wind is often used to indicate the size of wind speed. The "Beaufort Wind Scale" drawn up by Englishman F Beaufort in 1805 divides the wind power into 13 (0 ~ 12). From 1946, the wind level increased to 18 (0 ~ 17). Wind and gust have a great influence on aircraft flight. When taking off and landing, you must choose the appropriate direction according to the wind direction and wind speed on the ground; In flight, the drift must be corrected in time according to the wind direction and speed, so as to maintain a certain course and calculate the standard flight time. When building an airport, the runway direction must be determined according to the climatic data of the wind. In addition, the wind also has a great influence on the flight performance of aircraft. For example, when the plane flies against the wind, the lift of the plane will increase. Gust has a great influence on the flight load of aircraft, so it is necessary to give a model and strength standard to describe gust in aircraft design.
Definition of wind
The movement of air relative to the ground usually refers to its horizontal component, which is expressed by wind direction, wind speed or wind force. Wind direction refers to the direction of airflow, which is often recorded in the direction of 16. Wind speed is the horizontal distance that air moves in unit time, in meters per second. The horizontal wind speed in the atmosphere is generally 1.0 ~ 10 m/s, typhoons and tornadoes can sometimes reach 102 m/s, and the wind speed in farmland can be less than 0. 1 m/s. There are two kinds of observation data of wind speed: instantaneous value and average value, and the average value is generally adopted. Wind is measured by electric anemometer, portable anemometer, Dyne anemometer and hot ball anemometer, which is used to measure the breeze in farmland. It can also be estimated according to the wind level and the signs of ground objects.
The cause of wind
The direct cause of the wind is the uneven distribution of air pressure in the horizontal direction. Wind is comprehensively influenced by different factors such as atmospheric circulation, topography and water area, and its manifestations are various, such as monsoon, local sea-land wind, valley wind and foehn wind. Simply put, wind is the movement of air molecules. To understand the causes of wind, we must first understand two key concepts: air and air pressure. The components of air include nitrogen molecules (accounting for 78% of the total air volume), oxygen molecules (accounting for about 2 1%), water vapor and other trace components. All air molecules are moving at a very fast speed, colliding with each other and anything on the horizon.
Air pressure can be defined as the pressure exerted by air molecules in a given area. Generally speaking, the more air molecules exist in an area, the greater the air pressure in this area. Accordingly, wind is the result of pressure gradient force.
However, some changes in atmospheric pressure are caused by storms, some by uneven surface heating, and some by atmospheric molecules being forced to flow from a relatively high pressure area to a low pressure area in a certain horizontal area.
Most of the high-pressure and low-pressure belts shown on the weather map only form a mild breeze that accompanies us. However, the pressure difference required to generate the breeze only accounts for 1% of the atmospheric pressure itself, and this pressure change will occur in many areas. Relatively speaking, the formation of strong storms stems from the change of larger and more concentrated pressure areas.
The influence of the wind
Wind is one of the environmental factors of agricultural production. Moderate wind speed plays an important role in improving farmland environmental conditions. The increase of wind speed accelerates or strengthens the surface heat exchange, evapotranspiration of farmland and the transportation of carbon dioxide and oxygen in the air. Wind can spread plant pollen and seeds and help plants pollinate and reproduce. Wind energy is widely distributed and inexhaustible. Monsoon prevails in China, which is beneficial to the growth of crops. The Inner Mongolia Plateau, the Northeast Plateau, the southeast coast and the inland mountainous areas are rich in wind energy resources, which can be used as energy development and utilization.
Wind will also have a negative impact on agriculture. It can spread pathogens and plant diseases. High-altitude wind is a meteorological condition for the long-distance migration of pests such as armyworm, rice planthopper, rice leaf roller and locust. Strong wind causes mechanical wear of leaves, lodging of crops, broken trees, falling flowers and fruits, which affects the yield. Strong winds can also lead to soil erosion and sand dune movement, and destroy farmland. Blindly reclaiming wasteland in arid areas, wind will lead to land desertification. Strong winds and snowstorms in pastoral areas will disperse herds and aggravate freezing damage. Some special properties of local winds often cause wind disasters. Tidal wind with high salinity, scorching wind with high temperature and low temperature, and dry-hot wind blowing from the sea have seriously affected the flowering and fruiting of fruit trees and the filling of cereal crops. In order to prevent wind damage, wind-resistant varieties with dwarfing, lodging resistance and friction resistance are usually cultivated. It is more effective to build windbreaks and set up windbreaks.
wind energy
The kinetic energy formed by air flow is extremely wind energy. Wind energy is a conversion form of solar energy.
The radiation of the sun causes uneven heating of the earth's surface, uneven distribution of atmospheric pressure, and the air moves along the horizontal direction to form wind. The formation of wind is the result of air flow. The formation of wind energy utilization is mainly to convert the kinetic energy of atmospheric movement into other forms of energy.
In the equatorial and low latitudes, the solar altitude angle is large, the sunshine time is long, the solar radiation intensity is strong, the ground and atmosphere receive more heat and the temperature is high; At higher latitudes, the solar altitude angle is small, the sunshine time is short, the heat received by the ground and the atmosphere is less, and the temperature is low. This temperature difference between high latitude and low latitude forms a north-south pressure gradient, which makes the air move horizontally and the wind blows along the direction of the horizontal pressure gradient, that is, the vertical and isobars blow from high pressure to low pressure. The earth is spinning, and the force that deflects the horizontal movement of air is called geostrophic deflection force, which deflects the airflow in the northern hemisphere to the right and the airflow in the southern hemisphere to the right, so the atmospheric movement of the earth is not only affected by the pressure gradient force, but also by geostrophic deflection. The real motion of the atmosphere is the result of the comprehensive influence of these two forces.
In fact, the sea surface wind is not only dominated by these two forces, but also influenced by the ocean and topography to a great extent. Mountain passes and straits can change the direction of airflow and increase the wind speed, while the friction between hills and mountains reduces the wind speed, while isolated peaks increase the wind speed because of high altitude. Therefore, the temporal and spatial distribution of wind direction and wind speed is more complicated.
In winter, the mainland is colder than the ocean, and the pressure on the mainland is higher than the ocean. The wind blows from the mainland to the sea. In summer, on the other hand, the mainland is hotter than the ocean, and the wind blows inland from the ocean. This seasonal wind is called monsoon. The so-called land-sea breeze is that during the day, the air flow on the mainland is heated and expanded, rises to high altitude and flows to the ocean, and then cools and sinks over the ocean. The air flow near the surface of the ocean blows to the mainland to compensate for the rising air flow from the mainland. The low-level wind blows from the ocean to the mainland, which is called sea breeze. At night (winter), on the other hand, the low-level wind blows from the mainland to the ocean, which is called land wind. In mountainous areas, due to thermal reasons, it blows from the valley to the plain or hillside during the day and from the plain or hillside at night. The former is called valley wind and the latter is called mountain wind. This is because the hillside heats up quickly during the day, and the temperature is higher than the air temperature at the same height above the valley. The warm air on the hillside flows from the hillside to the valley, and the air in the valley supplements the air lost along the hillside. At this time, the wind blowing from the valley to the hillside is called valley wind. At night, the hillside is cooled by radiation, which is faster than the air at the same height. Cold air flows into the valley along the hillside, which is called mountain wind. When solar radiation can pass through the earth's atmosphere, the energy absorbed by the atmosphere is about 2 * 10 16W, and a small part of it is converted into kinetic energy of air. Because the tropics absorb more solar radiation energy than the polar regions, the atmospheric pressure difference leads to airflow and "wind". As for local areas, such as high mountains and deep valleys, the air at the top of the mountain is heated up by sunlight during the day, and the cold air in the deep valleys takes its place, so the wind blows from the deep valleys to the mountains; At night, the air on the mountain dissipates quickly, so the wind blows from the mountain to the deep valley. For another example, in coastal areas, due to the temperature difference between land and ocean during the day, sea breeze blows to land; On the contrary, the land wind blows to the sea at night.
Classification of wind
According to the phenomenon caused by the wind to the ground objects, the wind force is divided into 13 grades, which are called wind grades, and recorded by numbers of 0 ~ 12 grades.

3. Medical interpretation
The concept of TCM etiology, also known as wind evil. Wind evil has external and internal causes. External wind is a kind of climate or environmental state formed by air flow in nature. It is the main gas in spring and belongs to one of the six qi (see Qi). However, this kind of climate or environmental state will make people who are weak in vital qi or susceptible to constitution get sick. For these people, external wind becomes a pathogenic factor and belongs to one of the six evils. Internal wind refers to the pathological state caused by excessive yang in the body caused by various reasons, which is closely related to the pathological changes of the liver. Although there are differences between external wind and internal wind, they all have the characteristics of rapid onset and diverse changes in clinic.
Although wind is the main gas in spring, it exists in four seasons, so the diseases caused by external wind are not seasonal; Pathogens such as cold, dampness, dryness, and heat (fire) often attach to the wind and invade the human body, or the wind and phlegm-dampness in the body combine to cause disease. Such as exogenous wind-cold, wind-heat, rheumatism, wind-cold-dampness arthralgia, etc. Therefore, exogenous wind is often the forerunner of exogenous pathogenic factors and the main pathogenic factor of six evils, so there is a saying that "wind is the beginning of all diseases" and "wind is the length of all diseases". Exterior wind belongs to yang evil, which is light in nature and has the characteristics of ascending, ascending and external. Therefore, it often hurts the upper part of the human body (head and face), yang meridian and muscle surface, making the fur loose, causing headache, sweating and bad wind. External wind also has the characteristics of good behavior, so the disease site moves around after illness, and there is no fixed activity place. For example, wind arthralgia (walking arthralgia) is manifested as wandering joint pain; Rubella comes quickly and itches painfully, but sometimes it goes quickly and often leaves no trace after fading. There are many diseases and syndromes caused by exogenous wind, so it is necessary to determine the invaded human body parts and other pathogens (or properties) according to their symptoms and signs. Clinically, the most common disease is that exogenous wind-cold or heat-toxic wind invades human lung health, resulting in fever, headache, aversion to cold, cough and other symptoms, commonly known as colds. The syndrome and treatment of exogenous wind evil is always based on expelling wind, and other evil spirits are also treated, such as wind-cold cold with pungent temperature and wind-heat with pungent cold.
Internal wind is mostly caused by liver dysfunction, so it is also called liver wind moving internally. Different from the syndromes caused by external wind, the pathological state caused by internal wind can appear dizziness, convulsion, spasm, trembling, peristalsis, mouth and eyes in clinic. Oblique, even the symptoms of abnormal limb movements such as varus angle arch and stiff neck were compared by the ancients. There are many reasons for endogenous wind syndrome, including liver-yang transforming into wind, extreme heat generating wind, yin deficiency generating wind and blood deficiency generating wind, which leads to hyperactivity of yang in the body. Liver yang turns to wind, mostly due to emotional exhaustion, improper diet, excessive drinking and so on. , leading to liver depression into fire, or water containing no wood, liver yang hyperactivity, yin not controlling yang, liver yang hyperactivity into wind, rising to the top or pulse, resulting in death, unconsciousness, also known as "stroke" (roughly the same as cerebrovascular disease in western medicine), extremely hot wind mostly occurs in the extreme period of acute fever. Due to excessive heat pathogen, burning liver meridian and excessive yang heat, dizziness, convulsion and other symptoms appear. Wind movement due to yin deficiency is more common in the late stage of fever, or after severe sweating, vomiting and diarrhea. At this time, the vaginal fluid is exhausted, and the liver-governing meridians are not nourished, and muscle contracture can be seen clinically. Diseases such as hand and foot peristalsis. Blood deficiency leads to wind, which is mostly caused by insufficient hematopoiesis or excessive blood loss, insufficient blood stored in liver, dystrophy of tendons and veins, and internal movement of deficiency wind. Clinically, symptoms such as numbness of limbs, muscle twitching and even limb contracture can be seen. The diagnosis of endogenous wind syndrome should be based on their respective clinical symptoms and signs. Treatment should focus on their respective causes, such as calming the liver and calming the wind for those with liver yang, clearing away heat and calming the wind for those with extreme heat, nourishing yin and calming the wind for those with wind due to yin deficiency, and nourishing blood and calming the wind for those with wind due to blood deficiency.

wind
① Etiological terminology. It is one of the six evils. Also called ethos. Belonging to yang pathogen, it is the forerunner of exogenous diseases. Therefore, exogenous pathogens often have wind syndrome, which is often combined with other pathogens to cause diseases, such as wind cold, wind heat and wind dryness. "On Su Wenfeng": "Therefore, the wind is sick, and its change is due to its impermanence, which naturally gives birth to a good atmosphere." Its pathogenesis is often manifested as aversion to wind and cold, fever and migration variability. "On Su Wenfeng": "The wind is good and changeable, it is cold when it is open, and hot and stuffy when it is closed."
