The first grade encyclopedia knowledge typhoon 1. What is a typhoon?
Typhoon is a classification of tropical cyclones in Asia-Pacific countries or regions north of the equator and west of international date line.
In meteorology, according to the definition of the World Meteorological Organization, the sustained wind speed of tropical cyclone center reaches 12 (that is, more than 64 knots, more than 32.7 meters per second, or more than 1 18 kilometers per hour), which is called hurricane or other local synonyms. The synonym used in the Pacific Northwest is typhoon.
Both the World Meteorological Organization and the Japan Meteorological Agency regard this as the highest level of tropical cyclone, but some meteorological departments will set a higher level according to their needs, such as the strong typhoon and super typhoon at the China Central Meteorological Observatory and the Hong Kong Observatory, the strong typhoon in central weather bureau, Taiwan Province Province, and the super typhoon at the United States Typhoon Warning Center.

In the evening, the only blank in the sky slowly began to disappear, and finally it was completely swallowed up by dark clouds. As the wind comes and the rain goes, there are fewer pedestrians on the road.
At 7 o'clock, the typhoon really landed. The wind is blowing violently and unscrupulously, and for a while, it shows people its strength. With heavy rain in the wind, it collides with the objects that it can attack and land on the ground. Flowers and trees sway in the wind and rain, the trees bow their heads helplessly, the grass bends down sadly, and the delicate flowers endure the devastation of the wind and rain painfully. People are even more afraid to hide at home and open their eyes in fear to look at everything outside the window.
The wind is roaring and the rain is roaring. They seem to announce to people that the wind and rain will stay in the world forever and the bright sunshine will never return. But that's impossible. Finally, the wind is tired and the rain is tired. Their strength is gradually weakening. Slowly, slowly, they exhausted their extra physical strength and retired.
The next day, the sky cleared up, some trees held their heads high, but some trees were staggered, which was the price of overcoming the wind and rain. Similarly, some grass is deformed and some flowers are bent, but I think they are willing. In order to win, they have to sacrifice.
Looking at the clear sky and breathing the fresh air, I feel that I am also integrated into the vitality after the rain.
3. Typhoon knowledge
Typhoons and hurricanes are both strong tropical cyclones generated on the surface of tropical oceans, but they are called differently. Tropical cyclones that occur in the western part of the North Pacific Ocean and west of the international international date line, including the South China Sea, are called typhoons. Tropical cyclones in the Atlantic Ocean or the eastern North Pacific Ocean are called hurricanes, which means hurricanes in the United States and typhoons in the Philippines, China, Japan and East Asia. It is called a whirlwind in the southern hemisphere.
Typhoons are often accompanied by strong winds and heavy rains. The wind rotates counterclockwise.
Isobars and isotherms are approximately a set of concentric circles. The central air pressure is the lowest and the temperature is the highest.
(1) refers to the cyclone in the Asia-Pacific sea area. Example: the typhoon described in Joseph Conrad's novels; (2) Tropical cyclones in Philippine or China waters; (3) [Stage Manner of the Opera Actor]: The manner of the opera actor on the stage; The formation of the typhoon [edit this paragraph] The cause of the typhoon is uncertain, but it is known that it developed from the disturbance in the tropical atmosphere.
In the tropical ocean, the sea surface is exposed to direct sunlight, which makes the temperature of seawater rise, and the seawater is easy to evaporate into water vapor and spread in the air. Therefore, the air in the tropical ocean has high temperature and high humidity, and this air expands due to high temperature, resulting in the decrease of density and weight. The wind near the equator is weak, easy to rise, and convection occurs. At the same time, the surrounding cold air flows in to replenish and then rises again. This cycle will eventually make the temperature of the whole air column higher and the mass lower. Air flows from high pressure to low pressure, just as water flows from high pressure to low pressure, air with higher ambient pressure will flow to low pressure, thus forming "wind".
In summer, due to the direct sunlight moving from the equator to the north, the southeast trade winds in the southern hemisphere cross the equator and become southwest monsoon to invade the northern hemisphere. When they meet the northeast trade wind in the northern hemisphere, the air is forced to rise, thus increasing the convection. Due to the different directions of southwest monsoon and northeast trade wind, when they meet, they often cause fluctuations and vortices. The convergence caused by the southwest monsoon and the northeast trade wind and the continuation of the original convection make the vortex with low pressure continue to deepen, that is, the air around it accelerates to flow to the center of the vortex, and the faster the flow, the greater the wind speed; When the maximum wind speed near the ground reaches or exceeds17.2m per second, we call it a typhoon.
Judging from the typhoon structure, such a behemoth must have unique conditions. First of all, there must be a vast atmosphere with high temperature and high humidity.
The temperature and humidity of the bottom atmosphere on the tropical ocean surface are mainly determined by the sea surface temperature, and typhoons can only form on the warm ocean surface where the sea surface temperature is higher than 26℃-27℃ and the sea surface temperature is higher than 26℃-27℃ within 60 meters. Second, there should be an initial disturbance that the lower atmosphere converges to the center and the upper atmosphere diffuses outward. Moreover, the divergence of the upper layer must exceed the convergence of the lower layer in order to maintain enough updraft and continuously strengthen the disturbance of the lower layer; 3. The difference of vertical wind speed should not be too big, and the relative motion of the upper and lower air is very small, so that the latent heat released by water vapor condensation in the initial disturbance can be stored in the air column in the typhoon eye area, forming and strengthening the typhoon warm center structure; Fourth, there must be enough geostrophic deflection, and the earth's rotation is conducive to the formation of cyclonic vortices.
The geostrophic deflection force is close to zero near the equator and increases at the north and south poles. Typhoons basically occur on the ocean surface about 5 latitudes from the equator. Typhoon classification [edit this paragraph] Super typhoon: the maximum average wind speed near the center of the ground layer is ≥ 5 1.0m/s, that is, 16 or above.
Strong typhoon (STY): The maximum average wind speed near the bottom center is 41.5-50.9m/s, which is 14- 15. Typhoon (TY): the maximum average wind speed near the center of the ground floor is 32.7-4 1.4m/s, which is 12- 13.
Severe tropical storm (STS): the maximum average wind speed near the bottom center is 24.5-32.6m/s, that is, wind10-1. Tropical storm (TS): the maximum average wind speed near the bottom center 17.2-24.4m/s, that is, the wind force is 8-9.
Tropical depression (TD): the maximum average wind speed near the bottom center 10.8- 17. 1 m/s, that is, the wind force is 6-7. The path of typhoon [edit this paragraph] The direction and speed of typhoon movement depend on the force acting on the typhoon.
Power is divided into internal force and external force. The internal force is the resultant force from north to west caused by the different geostrophic skewness caused by the latitude difference between north and south within the typhoon range. The larger the typhoon range, the stronger the wind speed and the greater the internal force.
The external force is the force of the external environment flow field on the typhoon vortex, that is, the guiding force of the easterly belt of the basic airflow on the south side of the subtropical high in the northern hemisphere. Internal force mainly plays a role in the initial generation of typhoon, while external force is the leading force to manipulate the movement of typhoon, so typhoon basically moves from east to west.
Due to the influence of the shape, position and intensity of subtropical high, the typhoon's moving path is not uniform and becomes diverse. Take the typhoon moving path in the western North Pacific as an example, there are generally three moving paths: ① The westward typhoon moves from the east of the Philippines to the west, crosses the South China Sea, and finally lands in Hainan Island or northern Vietnam. This route mostly occurs in 10- 1 1 month, and 2006 is a typical example; (2) Landing type: The typhoon moved to the northwest, crossed the Taiwan Province Strait, landed in the coastal areas of Guangdong, Fujian and Zhejiang, and gradually weakened into a low pressure.
This typhoon has the greatest impact on China. In recent years, the two typhoons "90 15" and "97 1 1" which have the greatest impact on Jiangsu belong to this type, and the paths from July to August are basically the same; (3) Parabolic type: the typhoon moves to the northwest first. When approaching the eastern coast of China, turn to the northeast without landing and bypass Japan. The path is parabolic, mostly occurring in May-June and 9- 165438+ 10.
After the typhoon is formed, it will generally move out of the source and experience the evolution process of development, weakening and extinction. A mature typhoon has a circular vortex radius of 5000km ~ 1000km and a height of 15km~20km. Typhoon consists of three parts: peripheral area, maximum wind speed area and typhoon eye.
The wind speed in the peripheral area increases from outside to inside, with spiral clouds and precipitation; The strongest precipitation occurs in the maximum wind speed area, with an average width of 8km~ 19km, and there is a circular cloud wall between it and the typhoon eye; The eye of typhoon is located in the center of typhoon, the most common typhoon.

The reason why sorbet bubbles is because there is a lot of invisible water vapor in the outside air. When it comes to cold sorbet, it will liquefy into droplets when it is cold. It seems that the sorbet is bubbling.
5. Why do sunflowers always face the sun?
Sunflower stems contain a wonderful auxin. This auxin is very afraid of light. When it is illuminated, it will go to the backlight side, and the cells on the backlight side will multiply rapidly. Therefore, the backlit side will grow faster than the bright side, which will bend the sunflower to light.
5. Geographical knowledge about typhoons
Typhoon formation: born on the ocean surface about 5 latitudes above the equator.
Judging from the typhoon structure, such a behemoth must have unique conditions. First of all, there must be a vast atmosphere with high temperature and high humidity. The temperature and humidity of the bottom atmosphere on the tropical ocean surface are mainly determined by the sea surface temperature, and typhoons can only form on the warm ocean surface where the sea surface temperature is higher than 26℃-27℃ and the sea surface temperature is higher than 26℃-27℃ within 60 meters. Second, there should be an initial disturbance that the lower atmosphere converges to the center and the upper atmosphere spreads outward. Moreover, the divergence of the upper layer must exceed the convergence of the lower layer in order to maintain enough updraft and continuously strengthen the disturbance of the lower layer; Third, the vertical wind speed cannot be too different, and the relative motion between the upper and lower air is very small, so that the latent heat released by water vapor condensation in the initial disturbance can be stored in the air column in the typhoon eye area, forming and strengthening the typhoon warm center structure; Fourth, there must be enough geostrophic deflection, and the earth's rotation is conducive to the formation of cyclonic vortices. The geostrophic deflection force is close to zero near the equator and increases at the north and south poles. The typhoon occurred on the ocean surface about 5 latitudes from the equator.
How is a typhoon named?
Typhoon is a kind of tropical cyclone. Meteorologically, a typhoon refers to a tropical cyclone that occurs in the western part of the North Pacific Ocean (west of the international international date line, including the South China Sea), and the maximum sustained wind speed near the center reaches 12 and above (that is, more than 32.6 meters per second). As for tropical cyclones that occur in the Atlantic Ocean or the eastern North Pacific Ocean and reach the same intensity, they are called hurricanes. (For example, the United States is a hurricane) According to the regulations of the International Meteorological Organization, tropical cyclones occurring in the western North Pacific and the South China Sea are divided into five categories. The grades and names published in different places are sometimes slightly different.
6. Who has a summary of typhoon knowledge?
Typhoons and hurricanes are both strong tropical cyclones generated on the surface of tropical oceans, but they are called differently. Tropical cyclones that occur in the western part of the North Pacific Ocean and west of the international international date line, including the South China Sea, are called typhoons. Tropical cyclones in the Atlantic Ocean or the eastern North Pacific Ocean are called hurricanes, which means hurricanes in the United States and typhoons in the Philippines, China, Japan and East Asia. It is called a whirlwind in the southern hemisphere.
Typhoons are often accompanied by strong winds and heavy rains. The wind rotates counterclockwise.
Isobars and isotherms are approximately a set of concentric circles. The central air pressure is the highest and the temperature is the lowest.
(1) refers to the cyclone in the Asia-Pacific sea area. Example: the typhoon described in Joseph Conrad's novels; (2) Tropical cyclones in Philippine or China waters; Typhoon is formed because the tropical sea surface is directly exposed to the sun, which makes the sea water temperature rise, the sea water evaporates into steam, and the surrounding cold air flows in to replenish it, and then rises again. This cycle will eventually expand the whole airflow and form a "wind".
Due to the vastness of the ocean, the diameter of air circulation is increasing, even several kilometers. Due to the high-speed rotation of the earth from west to east, there is friction between the air column and the surface. The closer to the equator, the greater the friction, which makes the steering column rotate counterclockwise. (The southern hemisphere rotates clockwise. ) Because the earth rotates fast, the air column can't keep up with the speed of the earth's rotation, so it forms a westward sense, which also forms the typhoon and typhoon path we are talking about now.
The center of the typhoon is in the position where the wind direction is T-shaped. It is not difficult to judge the distance and direction of the wind center according to the wind direction and wind speed. Based on my 40-year observation of the trend of clouds before typhoon Lei, it is basically accurate to judge whether the typhoon passes through the local area.
The accuracy has been predicted to local areas many times. When the maximum wind speed near the ground reaches or exceeds17.2m per second, we call it a typhoon.
(The following does not represent my editor) Judging from the typhoon structure, such a huge behemoth must have unique conditions. First of all, there must be a vast atmosphere with high temperature and high humidity.
The temperature and humidity of the bottom atmosphere on the tropical ocean surface are mainly determined by the sea surface temperature, and typhoons can only form on the warm ocean surface where the sea surface temperature is higher than 26℃-27℃ and the sea surface temperature is higher than 26℃-27℃ within 60 meters. Second, there should be an initial disturbance in which the lower atmosphere converges to the center and the upper atmosphere spreads outward. Moreover, the divergence of the upper layer must exceed the convergence of the lower layer in order to maintain enough updraft and continuously strengthen the disturbance of the lower layer; 3.

The geostrophic deflection force is close to zero near the equator and increases at the north and south poles. Typhoons basically occur on the ocean surface about 5 latitudes from the equator. [Edit this paragraph] The source of the typhoon is distributed on the vast ocean surface of the northwest Pacific at low latitude.
The tropical disturbance in the northwest Pacific intensified and developed to the initial position of typhoon, with a relatively concentrated zone in latitude and longitude. East-west, tropical disturbances developed into typhoons, which were relatively concentrated in four sea areas.
(1) the sea surface in the north-central South China Sea (2) the sea surface east of the Philippine Islands and near the Ryukyu Islands (3) the sea surface near the Mariana Islands (4) the sea surface near the Marshall Islands [edit this paragraph] The classification of typhoons generates and develops a low-pressure system on the tropical ocean surface, which is called a tropical cyclone. Internationally, the intensity is determined by the maximum wind force near its center, which is classified as follows: 1. SuperTY typhoon: the maximum average wind speed near the bottom center is ≥ 5 1.0m/s, that is, 16 or more.
Strong typhoon (STY): The maximum average wind speed near the bottom center is 41.5-50.9m/s, which is 14- 15. Typhoon (TY): the maximum average wind speed near the center of the ground floor is 32.7-4 1.4m/s, which is 12- 13.
2. Weak typhoon and severe tropical storm (STS): the maximum average wind speed near the bottom center is 24.5-32.6m/s, that is, wind10-1. Tropical storm (TS): the maximum average wind speed near the bottom center 17.2-24.4m/s, that is, the wind force is 8-9.
Tropical depression (TD): the maximum average wind speed near the bottom center 10.8- 17. 1 m/s, that is, the wind force is 6-7. [Edit this paragraph] The path of typhoon The direction and speed of typhoon movement depend on the force acting on the typhoon.
Power is divided into internal force and external force. The internal force is the resultant force from north to west caused by the different geostrophic skewness caused by the latitude difference between north and south within the typhoon range.

8. Who has the knowledge of typhoon prevention?
● To prevent lightning strike, quickly cut off the power supply of various electrical appliances.
Close doors and windows to avoid being blown open by strong winds. Check and fasten windows and other objects that are easily blown open by the wind. If the glass is loose or broken, please stick adhesive tape on the glass to prevent the fragments from being blown away.
Don't stay near glass doors and windows. ● When encountering a typhoon, take refuge in a hut or cave. If there is no such place, choose a safe place where there is no danger of landslide or flood, such as highland, rock or forest.
When you have to move forward, you should also bend down and don't get caught in the rain. Wet clothes will take away your body temperature and cause imbalance. In case of strong wind, try to lie on the ground and flee to a wooded place, and don't hide under dead trees.
● Close the doors and windows and go out less. When the typhoon came, there was a strong wind and heavy rain.
Families should take preventive measures in advance, such as closing doors and windows to prevent rain, moving flower pots on windowsills or balconies to prevent falling, and so on. At the same time, when the typhoon comes, it is easy for some large billboards to fall down, trees to be blown down, and telephone poles to fall to the ground ... So citizens had better not go out when the typhoon comes, in case they are smashed, crushed and electrified.
● If the glass is damaged after typhoon and strong wind, please replace it in time. Typhoons and strong winds may cause water and electricity cuts, so we should make timely preparations for our daily life.
Typhoon prevention knowledge: avoid personal injury caused by typhoon disaster. Typhoon may cause casualties: 1. Strong winds may blow down buildings and high-altitude facilities, easily causing casualties. For example, all kinds of dilapidated houses, factories, sheds, temporary buildings (such as fences), projects under construction, municipal public facilities (such as street lamps), amusement facilities, cranes, construction elevators, scaffolding, telephone poles, trees, billboards and iron towers collapsed, causing injuries.
Therefore, before the arrival of the typhoon, it is necessary to move to a safe place in time to avoid the above-mentioned places where casualties are likely to occur, and never take shelter from the wind and rain in the above-mentioned places. 2. Strong wind will blow down high-altitude objects, which will easily cause casualties.
For example, flowerpots on balconies and roofs, outdoor air conditioners, awnings, solar water heaters, sundries on roofs, articles, tools and building materials scattered on construction sites are easily blown off by the wind, causing casualties. Therefore, please fix flowerpots and other items in time, and the construction enterprise will arrange and pile up the construction equipment, tools and sporadic materials to ensure safety.
3. Other circumstances in which strong winds may cause casualties. Such as: door and window glass, curtain wall glass, etc. Blown by strong wind, glass splashes and kills people; Pedestrians are blown down or fall into the water on roads, bridges and watersides, resulting in death, injury or drowning; The wire is blown off by the wind, causing pedestrians to get an electric shock; Ships at sea (inland) were overturned and sank by wind and waves, and vehicles driving on expressways, especially expressways, overturned, causing casualties.
Therefore, before the typhoon comes, please ask the masses to take shelter from the wind and rain in a safe place in time and try to avoid walking on dams and bridges near rivers, lakes and seas. As long as the ship returns to Hong Kong in time to take shelter from the wind and anchor, the personnel on board must go ashore to take shelter from the wind, and vehicles should try to avoid driving in the area affected by strong winds. ● To prevent lightning strike, quickly cut off the power supply of various electrical appliances.
