Historical typhoon track map

1. What do the six lines of the typhoon path represent? The six different lines in the typhoon track map indicate that there are multiple weather stations predicting the path, and the path predicted by each weather station is marked with lines of different colors.

Typhoon originated in tropical ocean, where the temperature is high and a large amount of seawater is evaporated into the air, forming a low pressure center. With the change of air pressure and the movement of the earth itself, the inflow of air also rotates, forming a counterclockwise air vortex, which is a tropical cyclone. As long as the temperature does not drop, this tropical cyclone will get stronger and stronger, and finally a typhoon will form.

Safety precautions during typhoon 1. Close the window. Take the things hanging outside into the house. If you are outdoors, find a tall building to avoid being blown away by a powerful typhoon. Don't stand in dangerous places, such as near thin objects. Try not to go out and stay calm. 6. Be sure to travel. It is recommended to take the train. 7. Please stay as far away from the construction site as possible. 8. Keep the news flowing. Pay attention to the weather forecast on the radio or TV. 9. Prepare candles and flashlights. Store food, drinking water, batteries and first aid supplies.

Typhoon warning standards are expressed in blue, yellow, orange and red respectively.

1. The blue warning signal indicates that it may or has been affected by tropical cyclones within 24 hours, and the average coastal or land wind force is above 6, or the gust is above 8 and may continue.

2. The yellow warning signal indicates that it may or has been affected by tropical cyclones within 24 hours, and the average wind force along the coast or land is above 8, or the gust is above 10 and may continue.

3. The orange warning signal indicates that it may or has been affected by tropical cyclones within 12 hours, and the average coastal or land wind force is above 10, or the gust is above 12 and may continue.

4. red warning signal indicated that it may be or has been affected by tropical cyclones within 6 hours, with the average coastal or land wind reaching more than 12, or the gust reaching more than 14 and possibly continuing.

Factors affecting typhoon movement The motive force of typhoon movement can be divided into internal force and external force. The internal force of typhoon is mainly caused by the geostrophic deflection force accompanied by the rotation, airflow convergence and upward movement of typhoon itself. The internal force of typhoon is directly proportional to the radius of typhoon, the convergence and upward movement of air in vortex and tangential wind, and inversely proportional to the latitude of typhoon center. Under the action of simple internal force, the moving track of typhoon center is a complex cycloid composed of sine wave and cosine wave with different amplitudes and the same period. The external force of typhoon mainly includes pressure gradient force, geostrophic deflection force and friction of environment (average airflow).

2. Classification of typhoon paths Typhoon paths can be roughly divided into three categories: ① Westward typhoons move from the east to the west of the Philippines, cross the South China Sea, and finally land in Hainan Island or northern Vietnam.

(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.

The two typhoons "90 15" and "97 1 1" which have had the greatest impact on Jiangsu in recent years belong to this type. (3) Parabolic type: The typhoon moves to the northwest first, then turns to the northeast when approaching the eastern coast of China, and turns to the vicinity of Japan, with a parabolic path.

Typhoon disaster. Typhoon is a very destructive and disastrous weather system, but sometimes it can also play a beneficial role in eliminating drought.

Its harmfulness mainly includes three aspects: ① strong wind. The maximum wind force near the typhoon center is generally above 8.

② Heavy rain. Typhoon is one of the strongest rainstorm weather systems. Generally, it can produce rainfall of 150mm~300mm in the area where typhoons pass, and a few typhoons can produce heavy rain above1000 mm.

The rainstorm caused by Typhoon Kloc-0/975 in the upper reaches of Huaihe River created the extreme rainstorm in Chinese mainland and caused the "75.8" flood in Henan. ③ Storm surge.

Generally, typhoons will increase water in coastal waters, and the maximum water increase in coastal areas of Jiangsu Province can reach 3m. Typhoons "9608" and "97 1 1" increased the water, which made Jiangsu's coastal areas along the Yangtze River appear unprecedented.

Looking down from space, the typhoon looks like a spinning top, and the trajectory of the spire of this virtual top is the typhoon path. Throughout the history of typhoons, the paths of typhoons are various, and there has never been a typhoon with the same path.

There are many reasons for the typhoon path, mainly because the typhoon is affected by complex atmospheric environment and other factors in the process of atmospheric movement. If the atmospheric environment is a big palette, then the newly generated typhoon is like a canvas. When it is painted with different colors by the atmosphere in motion, it will produce different paths.

At present, typhoons affecting China are mainly "born" in the western Pacific, and their common paths are as follows:

4. Throughout history, what are the main paths of typhoons? There are several main paths for typhoons, which are written into textbooks. The path of typhoon is mainly influenced by subtropical high and long wave in westerlies (double typhoon effect is not common). Usually, after typhoons are generated in the South China Sea or the Western Pacific at middle and low latitudes, they will move westward first.

If the subtropical high is strong, it will always move westward, affecting Guangdong, Guangxi, Yunnan and Vietnam in China;

The subtropical high is weak, and the long wave in the westerly belt is weak, then it turns north at the edge of the subtropical high 588 line, affecting Fujian and Zhejiang, and even entering the inland areas;

If the subtropical high is weak and the westerly belt is strong, it will turn to the north and then to the northeast, which may affect Japan as far as possible.

Mainly these three paths.

6.20 17 2 1 Typhoon road map /2 1 What's the name of typhoon? According to the analysis of the latest news roadmap of Typhoon No.217, with the arrival of an active period of the Pacific typhoon season, this year's typhoon will usher in another * * *.

With the formation of typhoons one after another, typhoons in the ocean will overwhelm us, not to mention the double wind dance, and there may not be a triple wind dance in the near future. The appearance of typhoons is very random.

Then, among the typhoons generated in the future, what is the name of Typhoon No.21? Now let's take a look at the latest news of typhoon 2 1. What was the name of Typhoon No.21in 20 17? Tropical Storm Lane (English: Tropical Storm Lan, international code: 172 1) is the first typhoon season in the Pacific Ocean in 20 17.

"Ryan" is the first time to use it, and it is the replacement name of 20 12 typhoon Vicente. The name is provided by the United States, and the name means storm. Naming of Typhoon Lanne: Tropical storms in the northwest Pacific are generally named by the Japan Meteorological Agency (Typhoon Center in Tokyo, Japan) with the international code of 17XX, while the tropical depression in this area is numbered with the letter W in the United States Joint Typhoon Warning Center.

The Philippine Atmospheric Geophysical and Astronomical Administration (PAGASA) will assign a Philippine name to all tropical depressions entering the Philippines or generated within the scope of Philippine storms for local early warning purposes. In addition, because Chinese mainland, Hong Kong and Macau (Chinese mainland, China, Hong Kong, China and Macau, China) use the same translation name, the translation name of Taiwan Province Province may be different, so the same storm may have two different Chinese names, and sometimes two different English names (international name and Philippine name). In August of 20 12, there was a name conflict between typhoon Vicente and the list of hurricanes in the northeast Pacific. Therefore, at the annual meeting of Typhoon Committee in 20 13, it was decided to delete Vicente from the list, and the replacement name was determined as Ryan the following year. This is a very rare case, because the name of the typhoon itself was deleted.

20 17 Pacific typhoon season 20 17 Pacific typhoon season: 20 17 February, which is in the severe winter season, is not suitable for the development of tropical cyclones. However, due to the weak subtropical high, the sea surface temperature east of the Philippines is obviously high, and the vertical wind shear is small, eventually forming two tropical depressions. In March, the subtropical high returned to Southeast Asia, the vertical wind shear increased again, and the phenomenon of empty platform appeared in the northwest Pacific. In the first half of April, the conditions gradually improved, the humidity of the low latitude ocean increased greatly, and the subtropical high temporarily withdrew from the tropical ocean stage. However, due to the large vertical wind shear, the development of tropical cyclones was greatly inhibited, so a tropical disturbance occurred in the low latitude ocean. Although the numerical forecast supported it to reach the intensity of tropical storm and above, in the end, its convection sometimes merged and sometimes fell apart, and it failed to become the first typhoon of 20 17. In late April, with the further reduction of vertical wind shear, typhoon Meihua, the first tropical storm of this year, appeared in the northwest Pacific. It is a weak tropical cyclone, and it is far from the land without any loss; In May, the southwest monsoon of the South China Sea broke out, but at the same time, the intensity of subtropical high reached its peak. Although there were many typhoon embryos, they all died in the end, resulting in no tropical storm in May.

7. Is the annual typhoon path basically a historical path? number

Typhoon refers to a tropical cyclone formed on the vast sea surface above 26℃ in tropical or subtropical areas. According to the definition of the World Meteorological Organization, tropical cyclones with sustained central wind speed of 12 to 13 (i.e. 32.7~4 1.4m/s) are typhoons or hurricanes.

According to the definition of Japan Meteorological Agency, the central sustained wind speed118 ~156 km/h (32.8 ~ 43.3 m/s) is called typhoon. The western part of the North Pacific (north of the equator, west of international date line, east of east longitude 100 degrees) is usually called a typhoon, while the North Atlantic and the East Pacific are generally called hurricanes.

Every summer and autumn, there are many violent storms called typhoons in the Pacific Northwest adjacent to China. Some dissipate at sea, while others land on land, bringing storms, which is a natural disaster.
