In August, typhoons piled up and attacked. The data revealed when and where China was most vulnerable to typhoons.

　　China Weather Network News After the "empty platform" in July, there have been many typhoons recently. Since August, four typhoons have been generated in the northwest Pacific Ocean and the South China Sea, among which Typhoon Hagupit No.4 and Typhoon Mikla No.6 have successively landed in the coastal areas of Yueqing, Zhejiang and Zhangpu, Fujian. So, is there a time rule for typhoon activities? When is the craziest? Where does it prefer to land? China Weather Network specially studied the big data from 1949 to 2019, and analyzed various "preferences" of typhoons.

　　China is prone to typhoons from July to September.

　　From the time of typhoon activity, typhoons may occur in the northwest Pacific and the South China Sea all year round. In China, the time range of typhoon landing is also very wide. Except for January to March, typhoons land in other months. According to the distribution of landfall in each month, the time of typhoon landing in China is mainly concentrated in summer and autumn, and the most concentrated period is from July to September.

　　According to meteorological big data, from 1949 to 2019, there were 130 typhoons landing in China in July and August, and the number of landings in September was 122, accounting for 78% of the year.

　　Typhoon "favors" Guangdong most.

　　According to meteorological big data, from 1949 to 2019, a total of 491 typhoons landed in China. From the landing place of typhoons, they can be "captured" from Sanya in Hainan in the south and Yingkou in Liaoning in the north. However, the landing sites for typhoons are Guangdong, Taiwan Province, Fujian and Hainan, among which Guangdong is the most popular.

　　Statistics show that in the past 71 years, a total of 189 typhoons landed in Guangdong. Because some typhoons landed many times, these 189 typhoons landed in Guangdong for 194 times, and the number and times of typhoons landing in Guangdong were the first in the country. The typhoon landed in Taiwan Province, Fujian and Hainan for more than 100 times.

　　In addition, there are typhoons "landing" in northern China. According to the statistical data from 1949 to 2019, there were 14 typhoons landing on the coast of Shandong and 6 typhoons landing on the coast of Liaoning. Among them, the 11th typhoon "Winnie" in 1997 landed in Yingkou, Liaoning on August 21st, 1997, which was the northernmost typhoon landing in China.

　　Hebei, Beijing, Jilin, Heilongjiang and other places have all been affected by the low pressure after typhoon weakening, the cloud system around the typhoon or the temperate cyclone after typhoon denaturation, and even typhoons have passed through.

　　Hualien, Taiwan is the most vulnerable county and city to typhoon in China.

　　From the specific landing point, Hualien, Taiwan is the county and city most vulnerable to typhoons in China. According to meteorological big data, there were as many as 37 typhoons landing in Hualien from 1949 to 2019. Wenchang and Wanning in Hainan, Taitung and Yilan in Taiwan, Xuwen and Yangjiang in Guangdong are also "typhoon-attracting" areas, and the number of typhoons landing has reached or exceeded 20.

　　Shao Peng, a meteorologist of China Weather Network, explained that although Guangdong is the most vulnerable province to typhoons, its coastline is long and there are many coastal counties and cities, while there are only a few counties and cities along the eastern coast of Taiwan Province and Hainan. On average, the number of typhoon landings in each county and city along the Guangdong coast will be relatively less, but the counties and cities along the eastern coast of Taiwan Province and Hainan are more frequently attacked by typhoons.

　　Among the counties and cities along the eastern coast of Taiwan Province, Hualien is the most vulnerable to typhoons, which is also closely related to its geographical location. Because the overall path of typhoons landing in Taiwan Province is northerly, Hualien, which is located in the north and occupies a long coastline, has thus become the most vulnerable area to typhoons.

　　The typhoons landing in China vary greatly from year to year.

　　According to meteorological big data, from 1949 to 2019, there were 1918 typhoons generated in the Pacific Northwest and the South China Sea, with an average of 27 typhoons generated each year, with an average of 6.9 typhoons landing in China each year. However, the generation and landing of typhoons do not follow the average law every year, but show great interannual changes.

　　In the year with many typhoons, 40 typhoons were generated in 1967; In 1998 and 2010, there were only 14 typhoons.

　　Judging from the number of landings each year, there are also great differences between years. The year when typhoons landed in China was 1971, and 12 typhoons landed in China. The years when typhoons landed in China were the least in 1950 and 1951, and only three typhoons landed.

　　The proportion of typhoons and strong tropical storms landing in China is the highest.

　　In terms of intensity, the typhoon landing in China is the strongest tropical storm, accounting for 31.2%; The proportion of typhoons and tropical storms is not small, accounting for 30.3% and 21.4% respectively; The number of strong typhoon and super typhoon landing in China is 63 and 21 respectively, accounting for 12.8% and 4.3% respectively.

　　Strong typhoons and super typhoons prefer to land in August-September, especially in September. According to meteorological big data, from 1949 to 2019, there were 122 typhoons that landed in China in September, of which 25 were strong typhoons and 7 were super typhoons, accounting for 26.2%. The proportion of strong typhoons and above when landing was the highest in each month.

　　Rammasun is the strongest typhoon that landed in China since 1949.

　　In the past 71 years, there were 21 typhoons landing in China with super typhoon level. Among them, when the No.9 typhoon "rammasun" landed in Wenchang, Hainan in 2014, the maximum wind force near the center reached 70 m/s, which was the strongest typhoon landing in China since 1949. Moreover, after landing in Hainan, rammasun continued to land in Guangdong and Guangxi, causing 7.423 million people and 4.685 million hectares of crops in 59 counties and cities in Hainan, Guangdong and Guangxi to be affected. The direct economic loss was about 26.55 billion yuan, and Nanning and other cities were waterlogged and seriously damaged.

　　In addition, when the No.8 typhoon "Opal" in 1962, No.12 typhoon "Wanda" in 1956, No.8 typhoon "Sang Mei" in 2006 and No.14 typhoon "Marge" in 1973 landed in China, the maximum winds near the center all reached 60 m/s and above. Together with "rammasun", these four typhoons became the top five in the typhoon power list.

　　Typhoons always come with wind and rain, which is extremely destructive. Before the arrival of typhoons, coastal residents should pay attention to defending against typhoons, especially strengthening their awareness of self-protection.

　　When a typhoon strikes, be sure to pay close attention to the typhoon dynamics and avoid going to the typhoon-affected areas; If the residential area is already in the typhoon-affected area, it is necessary to pay attention to cleaning the flowerpots on the external windows, the hanging objects on the balcony, etc., and reinforce the doors and windows in advance to avoid going out when the typhoon comes; When you have to go out, you should also pay attention to stay away from dangerous areas, such as near billboards, dangerous old houses and low-lying areas in mountainous areas.
