"Plum Blossom" has many login times.

Strong landing intensity

Strong winds have a wide range and a long duration.

The rainfall intensity is high.

Multiple landings

Typhoon Meihua has landed on the coast of China for four times.

Meihua is the third typhoon that landed in China for four times since 1949. The previous two typhoons were Yanxi (once in Taiwan Province Province and three in Fujian Province) and Fenghuang (twice in Taiwan Province Province, once in Zhejiang Province and once on 20 16).

But the four landings were in different provinces (cities), which is the first time since 1949. In addition, Meihua is the latest typhoon to land in Shandong and Liaoning since 1949.

Strong landing intensity

Typhoon Meihua landed in Putuo, Zhoushan, Zhejiang with a strong typhoon level (14, 42m/s), which is the strongest typhoon landing in China this year. It is also the strongest typhoon that landed in the north of Xiangshan Port and Zhoushan in Zhejiang Province in September since 1949. The landing intensity of Meihua in Fengxian, Shanghai is typhoon level (12,35m/s), which is the strongest typhoon that landed in Shanghai since 1950.

Strong winds have a wide range and a long duration.

Combined with cold air, the strong wind brought by typhoon Meihua has a wide range, strong intensity and long duration. The maximum gust is 8 ~ 10 in eastern Zhejiang, Shanghai, eastern Jiangsu, Shandong Peninsula and eastern Liaoning, and 12 ~ 15 in the coastal areas of Shanghai and Zhejiang. The largest gust occurred in Xugong Island, Zhoushan, Zhejiang, with a gust of 16 (53.6 m/s). The cumulative time of gale above 12 in the coastal area of northeast Zhejiang is as long as 12 hours.

Shanghai, Zhejiang, Jiangsu and Anhui * * * increased water resources11300 million cubic meters, and the water level in Taihu Lake rose by about 0. 1 meter. In addition, the concentrations of PM2.5 and PM 10 in East China decreased significantly, and the air quality improved.

Disadvantageously, "Plum Blossom" caused large-scale cancellation of flights in Zhejiang, Shanghai, Jiangsu, Shandong and other places, and some trains stopped and maritime navigation was suspended; In some areas such as Zhejiang and Jiangsu, crops were flooded, protective agriculture was damaged, trees fell and telephone poles were broken. Affected by plum blossoms, a storm surge of 100 to 200 cm occurred from Yancheng, Jiangsu to Jiaxing, Zhejiang from noon on 14 to noon on 15. September of 13 (August of lunar calendar 18) is the astronomical tide period, and its superposition effect has a negative impact on the drainage of the above coastal cities.
